 # Building Smack
 ## Linux
 Building Smack is as simple as
 ```
 git clone git@github.com:igniterealtime/Smack.git
 cd Smack
 gradle assemble
 ```
 ## Mac
 Smack requires a case-sensitive file system in order to build. Unfortunately, the macOS operating system is case-insensitive by default.
 To get around this, you can create a case-sensitive disk image to work from.
 1. Launch Disk Utility (Applications > Utilities)
 2. Click the +, or go to Edit > Add APFS Volume
 3. Give it a name, e.g. "Smack"
 4. Change the format to "APFS (Case-sensitive)"
 5. Click Add
 It'll auto-mount into /Volumes, e.g. /Volumes/Smack
 ```bash
 cd /Volumes/Smack
 git clone git@github.com:igniterealtime/Smack.git
 cd Smack
 gradle assemble
 ```
 ## Windows
 Smack requires a case-sensitive file system in order to build. Unfortunately, Windows NTFS is case-insensitive by default.
 To get around this, you can set specific folders as case-sensitive (requires Windows 10 v1803 or higher).
 In an Administrator console:
 ```batch
 fsutil.exe file SetCaseSensitiveInfo C:\git\Smack enable
 cd \git\Smack
 git clone git@github.com:igniterealtime/Smack.git
 cd Smack
 gradle assemble
 ```
 # IDE Config
 ### Eclipse
 Import IDE settings from `./resources/eclipse/` to configure proper ordering of imports and correct formatting that should pass the CheckStyle rules.
 ### IntelliJ IDEA
 Import Java Code Style settings from `./resources/intellij/smack_formatter.xml` to configure import optimisation and code formatting to pass the CheckStyle rules when building or submitting PRs.
 _We've noticed, at time of writing, that IntelliJ often requires a restart when applying new rules - no amount of OK/Apply will do the trick._
 # Smack Providers
 Providers are responsible for parsing the XMPP XML stream into new Java objects.
 ## Provider Design
 Assume you want to parse the following stanza extension element
 ```xml
 <myExtension attrFoo='fourthyTwo'>
  <myElement>Foo is greater then Bar</myElement>
  <myInfo alpha='true' delta='-1337'/>
 </myExtension>
 ```
 then the related provider would look like this
 ```java
 public MyExtension parse(XmlPullParser parser, int initialDepth) {
  MyElement myElement = null;
  MyInfo myInfo = null;
  String attrFoo = parser.getAttributeValue("", "attrFoo");
  // Main parsing loop, use a loop label instead of "boolean done"
  outerloop: while(true) {
    // Make sure to have already parse all attributes of the outermost element,
    // i.e. 'attrFoo' of 'myExtension' in this example. Then advance the parser
    XmlPullParser.Event event = parser.next();
    // Use switch/case of int instead of a if/else-if cascade
    switch (event) {
    case START_ELEMENT:
      // Determine the name of the element which start tag we are seeing
      String name = parser.getName();
      // We can use switch/case of Strings since Java7, make use of its advantages
      // and collect the values of the sub elements. If the sub elements are more
      // complex then those of this example, consider creating extra *private static*
      // parsing methods for them.
      switch(name) {
      case "myElement":
        // You should only use XmlPullParser.nextText() when the element is
        // required to have a text.
        myElement = new MyElement(parser.nextText());
        break;
      case "myInfo";
        // Use ParserUtils to parse Java primitives
        boolenan alpha = ParserUtils.getBooleanAttribute(parser, "alpha");
        int delta = ParserUtils.getIntegerAttribute(parser, "delta");
        myInfo = new MyInfo(alpha, delta);
        break;
      }
      break;
    case END_ELEMENT:
      // The abort condition with the break labeled loop statement
      if (parser.getDepth() == initialDepth) {
        break outerloop;
      }
      break;
    default:
      // Catch all for incomplete switch (MissingCasesInEnumSwitch) statement.
      break;
    }
  }
  // Create the actual class at the very end, design the classes as immutable as possible
  return new MyExtension(attrFoo, myElement, myInfo);
 }
 ```
 ## Common Pitfalls
 Use a `long` instead of `int` when the XML schema says `xs:unsignedInt`, because Java's `int` range is to small for this XML numeric data type.
 # Stanzas
 ## General Rules
 All classes which subclass `TopLevelStreamElement` and `ExtensionElement` must either
 1. be immutable (and ideally provide a Builder)
 2. implement `TypedCloneable`
 and must be `Serializable`.
 The reason that it must be either 1. or 2. is that it makes no sense to clone an inmutable instance.
 The preferred option is 1.
 Note that there is legacy code in Smack which does not follow these rules. Patches are welcome.
 ## ExtensionElement
 Extension elements are XML elements that are used in various parts and levels of stanzas.
 ## The static `from(Stanza)` Method
 Every ExtensionElement class must have a static `from()` method that retrieves that extension for a given Stanza (if any).
 Sample Code
 ```java
 public static RSMSet from(Stanza) {
  return packet.getExtension(ELEMENT, NAMESPACE);
 }
 ```
 Sometimes certain ExtensionElement's are only found in one stanza type, in that case, specify the parameter type. For example `public static CarbonExtension getFrom(Message)`.

 Smack's Modular Connection Architecture
 ======================================
 [Back](index.md)
 **Note: Everything related to the modular connection architecture is currently considered experimental and should not be used in production. Use the mature `XMPPTCPConnection` if you do not feel adventurous.
 Smack's modular connection architecture allows to extend a XMPP c2s (client-to-server) connection with additional functionality by adding modules.
 Those modules extend the Finite State Machine (FSM) within the `ModularXmppClientToServerConnection` with new states.
 Connection modules can either be
 - Transports
 - Extensions
 Transports bind the XMPP XML stream to an underlying transport like TCP, WebSockets, BOSH, and allow for the different particularities of transports like DirectTLS ([XEP-0368](https://xmpp.org/extensions/xep-0368.html)).
 This eventually means that a single transport module can implement multiple transport mechanisms.
 For example the TCP transport module implements the RFC6120 TCP and the XEP-0368 direct TLS TCP transport bindings.
 Extensions allow for a richer functionality of the connection. Those include
 - Compression
  - zlib ([XEP-0138](https://xmpp.org/extensions/xep-0138.html))
  - [Efficient XML Interchange (EXI)](https://www.w3.org/TR/exi/)
 - Instant Stream Resumption ([XEP-0397](https://xmpp.org/extensions/xep-0397.html)
 - Bind2
 - Stream Management
 Note that not all extensions work with every transport.
 For example compression only works with TCP-based transport bindings.
 Connection modules are plugged into the the modular connection via their constructor. and they usually declare backwards edges to some common, generic connection state of the FSM.
 Modules and states always have an accompanying *descriptor* type.
 `ModuleDescriptor` and `StateDescriptor` exist without an connection instance.
 They describe the module and state metadata, while their modules and states are instanciated once a modular connection is instanciated.

 Smack: XMPPConnection Management
 ================================
 [Back](index.md)
 Creating a Connection
 ---------------------
 The `org.jivesoftware.smack.XMPPConnection` interface manages your connection to
 an XMPP server. The default implementation is the
 `org.jivesoftware.smack.tcp.XMPPTCPConnection` class. The class contains three constructors. The simplest, `XMPPTCPConnection(CharSequence, String, String)` takes the username, password, and server name you'd like
 to connect to as arguments. All default connection settings will be used:
  * A DNS SRV lookup will be performed to find the exact address and port (typically 5222) that the server resides at.
  * The maximum security possible will be negotiated with the server, including TLS encryption, but the connection will fall back to lower security settings if necessary.
  * The XMPP resource name "Smack" will be used for the connection.
 Alternatively, you can use the `XMPPTCPConnection(ConnectionConfiguration)`
 constructor to specify advanced connection settings. Some of these settings
 include:
  * Manually specify the server address and port of the server rather than using a DNS SRV lookup.
  * Enable connection compression.
  * Customize security settings, such as flagging the connection to require TLS encryption in order to connect.
  * Specify a custom connection resource name such as "Work" or "Home". Every connection by a user to a server must have a unique resource name. For the user "jsmith@example.com", the full address with resource might be "jsmith@example.com/Smack". With unique resource names, a user can be logged into the server from multiple locations at once, or using multiple devices. The presence priority value used with each resource will determine which particular connection receives messages to the bare address ("jsmith@example.com" in our example).
 Connect and Disconnect
 ----------------------
 ```
 // Create the configuration for this new connection
 XMPPTCPConnectionConfiguration.Builder configBuilder = XMPPTCPConnectionConfiguration.builder();
 configBuilder.setUsernameAndPassword("username", "password");
 configBuilder.setResource("SomeResource");
 configBuilder.setXmppDomain("jabber.org");
 AbstractXMPPConnection connection = new XMPPTCPConnection(configBuilder.build());
 // Connect to the server
 connection.connect();
 // Log into the server
 connection.login();
 ...
 // Disconnect from the server
 connection.disconnect();
 ```
 By default Smack will try to reconnect the connection in case it was abruptly
 disconnected. The reconnection manager will try to immediately
 reconnect to the server and increase the delay between attempts as successive
 reconnections keep failing._
 In case you want to force a reconnection while the reconnection manager is
 waiting for the next reconnection, you can just use _AbstractXMPPConnection#connect()_
 and a new attempt will be made. If the manual attempt also failed then the
 reconnection manager will still continue the reconnection job.

 Debugging with Smack
 ====================
 [Back](index.md)
 Smack includes two built-in debugging consoles that will let you track
 all XML traffic between the client and server. A lite debugger and an
 enhanced debugger contained in `smack-debug.jar`, and a console debugger in `smack-core.jar`.
 Debugging mode can be enabled in two different ways:
  1. Add the following line of code **before** creating new connections:
 `SmackConfiguration.DEBUG = true;`
  2. Set the Java system property `smack.debugEnabled` to true. The system property can be set on the command line such as:
 `java -Dsmack.debugEnabled=true SomeApp `
 If you wish to explicitly disable debug mode in your application, including
 using the command-line parameter, add the following line to your application
 before opening new connections:
 `SmackConfiguration.DEBUG = false;`
 Smack uses the following logic to decide the debugger console to use:
  1. It will first try use the debugger class specified in the Java system property `smack.debuggerClass`. If you need to develop your own debugger, implement the `SmackDebugger` interface and then set the system property on the command line such as:
 `java -Dsmack.debuggerClass=my.company.com.MyDebugger SomeApp `
  2. If step 1 fails then Smack will try to use the enhanced debugger. The file `smack-debug.jar` contains the enhanced debugger. Therefore you will need to place the jar file in the classpath. For situations where space is an issue you may want to only deploy `smack-core.jar` in which case the enhanced and lite debugger won't be available, but only the console debugger.
  3. The last option if the previous two steps fail is to use the console debugger. The console debugger is a very good option for situations where you need to have low memory footprint.
 Enhanced Debugger
 -----------------
 ![Full Debug Window](images/enhanceddebugger.png) When debugging mode is
 enabled, a debug window will appear containing tabs for each new created
 connection. The window will contain the following information:
  * XMPPConnection tabs -- each tab shows debugging information related to the connection.
  * Smack info tab -- shows information about Smack (e.g. Smack version, installed components, etc.).  The connection tab will contain the following information:
  * All Stanzas -- shows sent and received packets information parsed by Smack.
  * Raw Sent Stanzas -- raw XML traffic generated by Smack and sent to the server.
  * Raw Received Stanzas -- raw XML traffic sent by the server to the client.
  * Ad-hoc message -- allows to send ad-hoc packets of any type.
  * Information -- shows connection state and statistics.
 Lite Debugger
 -------------
 ![Lite Debug Window](images/debugwindow.gif) When debugging mode is enabled, a
 debug window will appear when each new connection is created. The window will
 contain the following information:
  * Client Traffic (red text) -- raw XML traffic generated by Smack and sent to the server.
  * Server Traffic (blue text) -- raw XML traffic sent by the server to the client.
  * Interpreted Stanzas (green text) -- shows XML packets from the server as parsed by Smack.  Right click on any of the panes to bring up a menu with the choices to copy of the contents to the system clipboard or to clear the contents of the pane.

 Smack's Integration Test Framework
 ==================================
 Introduction
 ------------
 Smack's Integration Test Framework is used to run a set of tests against a real XMPP service.
 The framework discovers on start-up the available tests by reflection.
 Quickstart
 ----------
 You can run the framework against an XMPP service with
 ```bash
 $ gradle integrationTest -Dsinttest.service=my.xmppservice.org
 ```
 Note that the service needs to have In-Band Registration (IBR) enabled.
 A better alternative to IBR is using XEP-0133: Service Administration
 to create the throw away accounts used by the integration test
 framework. Simply use
 ```bash
 $ gradle integrationTest -Dsinttest.service=my.xmppservice.org \
                         -Dsinttest.adminAccountUsername=admin \
 						 -Dsinttest.adminAccountPassword=aeR0Wuub
 ```
 to run Smack's integration test framework against `my.xmppservice.org`
 with an admin account named `admin` and `aeR0Wuub` as password.
 Configuration
 -------------
 The framework is configured with a standard Java properties file.
 This file simply contains key/value pairs, which are separated by an equals sign ("=").
 The most important configuration value is the `service` value, it's also the only required setting.
 The file properties can be overridden with Java system properties.
 The name of a system property that is used by the framework needs to be prefixed with `sinttest.` (*S*mack *Int*egration *Test* Framework).
 For example the `service` property becomes `sinttest.service`.
 ### Minimal example **properties** file
 ```bash
 service=example.org
 ```
 ### Another example **properties** file
 ```bash
 service=example.org
 serviceTlsPin=CERTSHA256:2F:92:C9:4D:30:58:E1:05:21:9A:57:59:5F:6E:25:9A:0F:BF:FF:64:1A:C3:4B:EC:06:7D:4A:6F:0A:D5:21:85

 | dnsResolver          | One of 'minidns', 'javax' or 'dnsjava'. Defaults to 'minidns'.              |
 ### Where to place the properties file
 The framework will first load the properties file from `~/.config/smack-integration-test/properties`
 ### Running selected tests only
 Using `enabledTests` is is possible to run only selected tests. The
 tests can be selected on a per class base or by specifying concrete
 test methods. In the latter case, the methods must be qualified by a
 (simple) class name.
 For example:
 ```bash
 $ gradle integrationTest -Dsinttest.enabledTests=SoftwareInfoIntegrationTest.test
 ```
 will only run the `test()` method of `SoftwareInfoIntegrationTest`, whereas
 ```bash
 $ gradle integrationTest -Dsinttest.enabledTests=SoftwareInfoIntegrationTest
 ```
 would run all tests defined in the `SoftwareInfoIntegrationTest` class.
 Overview of the components
 --------------------------
 Package `org.igniterealtime.smack.inttest`
 ### `SmackIntegrationTestFramework`
 Contains `public static void main` method, i.e. the entry point for the framework.
 Here the available integration tests are discovered by means of reflection, the configuration is read and a `IntegrationTestEnvironment` instance created, which includes the XMPPConnections.
 ### `AbstractSmackIntegrationTest`
 The base class that integration tests need to subclass.
 ### `AbstractSmackLowLevelIntegrationTest`
 Allows low level integration test, i.e. every test method will have its own exclusive XMPPTCPConnection instances.
 ### `AbstractSmackSpecificLowLevelIntegrationTest`
 Operates, like `AbstractSmackLowLevelIntegrationTest` on its own `XMPPConnection` instances, but is limited to a particular type of `XMPPConnection`.
 ### `IntegrationTestEnvironment`
 The environment, e.g. the `XMPPConnections` provided to the integration tests by the framework. Note that for convenience `AbstractSmackIntegrationTest` contains some of those as protected members.
 ### `SmackIntegrationTest`
 An annotation that needs to be added to all methods that represent a single integration test.
 Annotated integration test methods must not take any arguments (i.e. their parameter count is 0), and should return void as it's not evaluated in any way.
 The methods are supposed to throw an exception if their integration test fails.
 ### `TestNotPossibleException`
 Can be thrown by test methods or constructors to signal that their test is not possible, e.g. because the service does not support the required feature.
 Running the integration tests
 -----------------------------
 Smack's Gradle build system is configured with a special task called `integrationTest`, which means you can run the tests simply with
 ```bash
 $ gradle integrationTest -Dsinttest.service=my.xmppservice.org
 ```
 If one of `accountOneUsername`, `accountOnePassword`, `accountTwoUsername` or `accountTwoPassword` is not configured, then the framework will automatically create the accounts on the service. Of course this requires account registration (IBR) to be enabled.
 If the accounts got created automatically by the framework, then they will also be deleted at the end of the test.
 Implementing Integration Tests
 ------------------------------
 Create a new class which extends `AbstractSmackIntegrationTest`.
 Every non-static method, including the constructor, of this class will have two XMPPConnections available to perform the integration tests with: `conOne` and `conTwo`.
 You can use the constructor to check if the XMPP service does provide the required XMPP feature.
 If it does not, simply throw a `TestNotPossibleException`.
 Test methods must be `public`, take zero arguments i.e. declare no parameters and be annoated with `@SmackIntegrationTest`.
 If the test method is not able to perform a test then it should throw a `TestNotPossibleException`.
 ### Rules for integration tests
 Tests should not leave any traces on the service if they are finished, i.e. the service state at the end of the test must be equal to the state of the beginning.
 It must be possible to run the tests in parallel.
 ### Why are there two mechanisms to signal that the test is not possible?
 Because the XMPP service may provide a component that is required to perform a certain integration test, but that component may not support all features.
 For example, the XMPP service may provides a PubSub (XEP-0060) component, but this component may not support all features of XEP-0060.
 ### Low-Level Integration Tests
 Classes that implement low-level integration tests need to sublcass `AbstractSmackLowLevelIntegrationTest`.
 The test methods can declare as many parameters as they need to, but every parameter must be of type `XMPPTCPConnection`.
 The framework will automatically create, register and login the connections.
 After the test is finished, the connections will be unregistered with the XMPP service and terminated.
 Debugging Integration Tests
 ------------------------------
 A test, like any other code, may not be perfect on the first attempt, and you may require more information in order to ascertain quite what's wrong.
 ### Smack Debugger options
 As listed in the main Smack [Debugging](../debugging.md) doc, there are two built-in debuggers that could surface you more information. Using the 'enhanced' debugger config option listed above, you'll get the Smack Debug Window launching when your tests launch, and you'll get a stanza-by-stanza account of what happened on each connection, hopefully enough to diagnose what went wrong.
 ### Debugging in the IDE
 If the output isn't enough, you may need to debug and inspect running code within the IDE. Depending on the IDE, in order to get execution to pause at your breakpoints, you may need to switch your configuration. Instead of running `gradle integrationTest`, instead run the `SmackIntegrationTestFramework` class directly with the same command-line options.
 Running your own integration tests
 ----------------------------------
 The framework can be used to run your own tests residing outside of the framework's default package scope.
 Simply set the `testPackages` property to a comma separated list of package names where the framework should look for integration tests.
 Example:
 ```bash
 $ gradle integrationTest -Dsinttest.service=my.xmppserivce.org -Dsinttest.testPackages=org.mypackage,org.otherpackage
 ```

 Smack Providers
 ===============
 Providers are responsible for parsing the XMPP XML stream into new Java objects.
 Provider Design
 ---------------
 Assume you want to parse the following stanza extension element
 ```xml
 <myExtension attrFoo='fourthyTwo'>
  <myElement>Foo is greater then Bar</myElement>
  <myInfo alpha='true' delta='-1337'/>
 </myExtension>
 ```
 then the related provider would look like this
 ```java
 public MyExtension parse(XmlPullParser parser, int initialDepth) {
  MyElement myElement = null;
  MyInfo myInfo = null;
  String attrFoo = parser.getAttributeValue("", "attrFoo");
  // Main parsing loop, use a loop label instead of "boolean done"
  outerloop: while(true) {
    // Make sure to have already parse all attributes of the outermost element,
    // i.e. 'attrFoo' of 'myExtension' in this example. Then advance the parser
    XmlPullParser.Event event = parser.next();
    // Use switch/case of int instead of a if/else-if cascade
    switch (event) {
    case START_ELEMENT:
      // Determine the name of the element which start tag we are seeing
      String name = parser.getName();
      // We can use switch/case of Strings since Java7, make use of its advantages
      // and collect the values of the sub elements. If the sub elements are more
      // complex then those of this example, consider creating extra *private static*
      // parsing methods for them.
      switch(name) {
      case "myElement":
        // You should only use XmlPullParser.nextText() when the element is
        // required to have a text.
        myElement = new MyElement(parser.nextText());
        break;
      case "myInfo";
        // Use ParserUtils to parse Java primitives
        boolenan alpha = ParserUtils.getBooleanAttribute(parser, "alpha");
        int delta = ParserUtils.getIntegerAttribute(parser, "delta");
        myInfo = new MyInfo(alpha, delta);
        break;
      }
      break;
    case END_ELEMENT:
      // The abort condition with the break labeled loop statement
      if (parser.getDepth() == initialDepth) {
        break outerloop;
      }
      break;
    default:
      // Catch all for incomplete switch (MissingCasesInEnumSwitch) statement.
      break;
    }
  }
  // Create the actual class at the very end, design the classes as immutable as possible
  return new MyExtension(attrFoo, myElement, myInfo);
 }
 ```
 Common Pitfalls
 ---------------
 Use a `long` instead of `int` when the XML schema says `xs:unsignedInt`, because Java's `int` range is to small for this XML numeric data type.

 General Rules
 =============
 All classes which subclass `TopLevelStreamElement` and `ExtensionElement` must either
 1. be immutable (and ideally provide a Builder)
 2. implement `TypedCloneable`
 and must be `Serializable`.
 The reason that it must be either 1. or 2. is that it makes no sense to clone an inmutable instance.
 The preferred option is 1.
 Note that there is legacy code in Smack which does not follow these rules. Patches are welcome.
 ExtensionElement
 ================
 Extension elements are XML elements that are used in various parts and levels of stanzas.
 The static `from(Stanza)` Method
 --------------------------------
 Every ExtensionElement class must have a static `from()` method that retrieves that extension for a given Stanza (if any).
 Sample Code
 ```java
 public static RSMSet from(Stanza) {
  return packet.getExtension(ELEMENT, NAMESPACE);
 }
 ```
 Sometimes certain ExtensionElement's are only found in one stanza type, in that case, specify the parameter type. For example `public static CarbonExtension getFrom(Message)`.

 DNSSEC and DANE
 ===============
 [Back](index.md)
 **DNSSEC and DANE support in Smack and MiniDNS is still in its
 infancy. It should be considered experimental and not ready for
 production use at this time.** We would like to see more thorough
 testing and review by the security community. If you can help, then
 please do not hesitate to contact us.
 About
 -----
 DNSSEC ([RFC 4033](https://tools.ietf.org/html/rfc4033) and others)
 authenticates DNS answers, positive and negative ones. This means that
 if a DNS response secured by DNSSEC turns out to be authentic, then
 you can be sure that the domain either exists, and that the returned
 resource records (RRs) are the ones the domain owner authorized, or
 that the domain does not exists and that nobody tried to fake its non
 existence.
 The tricky part is that an application using DNSSEC can not determine
 whether a domain uses DNSSEC, does not use DNSSEC or if someone
 downgraded your DNS query using DNSSEC to a response without DNSSEC.
 [DANE](https://tools.ietf.org/html/rfc6698) allows the verification of
 a TLS certificate with information stored in the DNS system and
 secured by DNSSEC. Thus DANE requires DNSSEC.
 Prerequisites
 -------------
 From the three DNS resolver providers (MiniDNS, javax, dnsjava)
 supported by Smack only [MiniDNS](https://github.com/rtreffer/minidns)
 currently supports DNSSEC. MiniDNS is the default resolver when
 smack-android is used. For other configurations, make sure to add
 smack-resolver-minidns to your dependencies and call
 `MiniDnsResolver.setup()` prior using Smack (e.g. in a `static {}`
 code block).
 DNSSEC API
 ----------
 Smack's DNSSEC API is very simple: Just use
 `ConnectionConfiguration.Builder..setDnssecMode(DnssecMode)` to enable
 DNSSEC. `DnssecMode` can be one of
 - `disabled`
 - `needsDnssec`
 - `needsDnssecAndDane`
 The default is `disabled`.
 If `needsDnssec` is used, then Smack will only connect if the DNS
 results required to determine a host for the XMPP domain could be
 verified using DNSSEC.
 If `needsDnssecAndDane` then DANE will be used to verify the XMPP
 service's TLS certificate if STARTTLS is used. Note that you may want
 to configure
 `ConnectionConfiguration.Builder.setSecurityMode(SecurityMode.required)`
 if you use this DNSSEC mode setting.
 Best practices
 --------------
 We recommend that applications using Smack's DNSSEC API do not ask the
 user if DNSSEC is avaialble. Instead they should check for DNSSEC
 suport on every connection attempt. Once DNSSEC support has been
 discovered, the application should use the `needsDnssec` mode for all
 future connection attempts. The same scheme can be applied when using
 DANE. This approach is similar to the scheme established by
 to
 ["HTTP Strict Transport Security" (HSTS, RFC 6797)](https://tools.ietf.org/html/rfc6797).

 Entity Capabilities
 ===================
 [Back](index.md)
 This section details the usage of Smacks implementation of Entity
 Capabilities.
 **XEP related:** [XEP-0115: Entity Capabilities](http://xmpp.org/extensions/xep-0115.html)
 **Description**
 Entity Capabilities is an XMPP Protocol extension, which, in order to minimize
 network impact, caches the capabilities of XMPP entities. Those capabilities
 are determined with the help of the Service Discovery Protocol
 ([XEP-0030](http://xmpp.org/extensions/xep-0030.html)).
 **Usage**
 Entity Capabilities work silently in the background when enabled. If the remote
 XMPP entity does not support XEP-0115 but XEP-0030 then XEP-0030 mechanisms
 are transparently used. You can enable or disable Entity Capabilities by using
 _**EntityCapsManager**_.
 The cache used by Smack for Entity Capabilities is non-persistent as default.
 That is, the cache only uses memory. But it is also possible to set a
 persistent Entity Capabilities cache, which is recommended.
 **Examples**
 Enable Entity Capabilities
 ```
 // Get an instance of entity caps manager for the specified connection
 EntityCapsManager mgr = EntityCapsManager.getInstanceFor(connection);
 // Enable entity capabilities
 mgr.enableEntityCaps();
 ```
 Configure a persistent cache for Entity Capabilities
 ```
 // Get an instance of entity caps manager for the specified connection
 EntityCapsManager mgr = EntityCapsManager.getInstanceFor(connection);
 // Create an cache, see smackx.entitycaps.cache for pre-defined cache implementations
 EntityCapsPersistentCache cache = new SimpleDirectoryPersistentCache(new File("/foo/cachedir"));
 // Set the cache
 mgr.setPersistentCache(cache);

 Consistent Colors
 =================
 [Back](index.md)
 Since XMPP can be used on multiple platforms at the same time,
 it might be a good idea to render given Strings like nicknames in the same
 color on all platforms to provide a consistent user experience.
 The utility class `ConsistentColor` allows the generation of colors to a given
 string following the specification of [XEP-0392](https://xmpp.org/extensions/xep-0392.html).
 ## Usage
 To generate a consistent color for a given string, call
 ```
 float[] rgb = ConsistentColor.RGBFrom(input);
 ```
 The resulting float array contains values for RGB in the range of 0 to 1.
 ## Color Deficiency Corrections
 Some users might suffer from color vision deficiencies. To compensate those deficiencies,
 the API allows for color correction. The color correction mode is a static value, which can be changed at any time.
 To correct colors for users with red-green color deficiency use the following code:
 ```
 ConsistentColor.activateRedGreenBlindnessCorrection();
 ```
 For color correction for users with blue-blindness, call
 ```
 ConsistentColor.activateBlueBlindnessCorrection();
 ```
 To deactivate color vision deficiency correction, call
 ```
 ConsistentColor.deactivateDeficiencyCorrection();

 Data Forms
 ==========
 [Back](index.md)
 Allows the exchange of structured data between users and applications for common
 tasks such as registration and searching using Forms.
  * Create a Form to fill out
  * Answer a Form
 **XEP related:** [XEP-4](http://www.xmpp.org/extensions/xep-0004.html)
 Create a Form to fill out
 -------------------------
 **Description**
 An XMPP entity may need to gather data from another XMPP entity. Therefore,
 the data-gathering entity will need to create a new Form, specify the fields
 that will conform to the Form and finally send the Form to the data-providing
 entity.
 **Usage**
 In order to create a Form to fill out use the _**Form**_'s constructor passing
 the constant **DataForm.type.form** as the parameter. The next step is to create
 the form fields and add them to the form. In order to create and customize a
 _**FormField**_ use the _**FormField**_'s constructor specifying the variable
 name of the field as the parameter. Then use **setType(FormField.Type type)** to set
 the field's type (e.g. FormField.Type.hidden, FormField.Type.text_single).
 Once we have the _**Form**_ instance and the _**FormFields**_, the last step is
 to send **addField(FormField field)** for each field that we want to add to
 the form.
 Once the form to fill out is finished we will want to send it in a message.
 Send **getDataFormToSend()** to the form and add the answer as an extension to
 the message to send.
 **Examples**
 In this example we can see how to create and send a form to fill out:
 ```
 // Create a new form to gather data
 Form formToSend = new Form(DataForm.Type.form);
 formToSend.setInstructions("Fill out this form to report your case.\nThe case will be created automatically.");
 formToSend.setTitle("Case configurations");
 // Add a hidden variable to the form
 FormField field = new FormField("hidden_var");
 field.setType(FormField.Type.hidden);
 field.addValue("Some value for the hidden variable");
 formToSend.addField(field);
 // Add a fixed variable to the form
 field = new FormField();
 field.addValue("Section 1: Case description");
 formToSend.addField(field);
 // Add a text-single variable to the form
 field = new FormField("name");
 field.setLabel("Enter a name for the case");
 field.setType(FormField.Type.text_single);
 formToSend.addField(field);
 // Add a text-multi variable to the form
 field = new FormField("description");
 field.setLabel("Enter a description");
 field.setType(FormField.Type.text_multi);
 formToSend.addField(field);
 // Create a chat with "user2@host.com"
 Chat chat = ChatManager.getInstanceFor(conn1).chatWith("user2@host.com" );
 Message msg = new Message();
 msg.setBody("To enter a case please fill out this form and send it back");
 // Add the form to fill out to the message to send
 msg.addExtension(formToSend.getDataFormToSend());
 // Send the message with the form to fill out
 chat.send(msg);
 ```
 Answer a Form
 -------------
 **Description**
 Under many situations an XMPP entity could receive a form to fill out. For
 example, some hosts may require to fill out a form in order to register new
 users. Smack lets the data-providing entity to complete the form in an easy
 way and send it back to the data-gathering entity.
 **Usage**
 The form to fill out contains useful information that could be used for
 rendering the form. But it cannot be used to actually complete it. Instead
 it's necessary to create a new form based on the original form whose purpose
 is to hold all the answers.
 In order to create a new _**Form**_ to complete based on the original
 _**Form**_ just send **createAnswerForm()** to the original _**Form**_. Once
 you have a valid form that can be completed, all you have to do is
 send **setAnswer(String variable, String value)** to the form where variable
 is the variable of the _**FormField**_ that you want to answer and value is
 the String representation of the answer. If the answer consists of several
 values you could then use **setAnswer(String variable, List values)** where
 values is a List of Strings.
 Once the form has been completed we will want to send it back in a message.
 Send **getDataFormToSend()** to the form and add the answer as an extension to
 the message to send back.
 **Examples**
 In this example we can see how to retrieve a form to fill out, complete the
 form and send it back:
 ```
 // Get the message with the form to fill out
 Chat chat2 = ChatManager.getInstanceFor(conn).addIncomingListener(
 	new IncomingChatMessageListener() {
 		@Override public void newIncomingMessage(EntityBareJid from, Message message, Chat chat) {
 			// Retrieve the form to fill out from the message
 			Form formToRespond = Form.getFormFrom(message);
 			// Obtain the form to send with the replies
 			Form completedForm = formToRespond.createAnswerForm();
 			// Add the answers to the form
 			completedForm.setAnswer("name", "Credit card number invalid");
 			completedForm.setAnswer("description", "The ATM says that my credit card number is invalid");
 			Message msg2 = new Message();
 			msg2.setBody("To enter a case please fill out this form and send it back");
 			// Add the completed form to the message to send back
 			msg2.addExtension(completedForm.getDataFormToSend());
 			// Send the message with the completed form
 			chat.send(msg2);		
 		}
 	});

 Service Discovery
 =================
 [Back](index.md)
 The service discovery extension allows one to discover items and information about
 XMPP entities. Follow these links to learn how to use this extension.
  * Manage XMPP entity features
  * Provide node information
  * Discover items associated with an XMPP entity
  * Discover information about an XMPP entity
  * Publish publicly available items
 **XEP related:** [XEP-30](http://www.xmpp.org/extensions/xep-0030.html)
 Manage XMPP entity features
 ---------------------------
 **Description**
 Any XMPP entity may receive a discovery request and must answer with its
 associated items or information. Therefore, your Smack client may receive a
 discovery request that must respond to (i.e., if your client supports XHTML-
 IM). This extension automatically responds to a discovery request with the
 information that you previously configured.
 **Usage**
 In order to configure the supported features by your client you should first
 obtain the ServiceDiscoveryManager associated with your XMPPConnection. To get
 your ServiceDiscoveryManager send **getInstanceFor(connection)** to the class
 _**ServiceDiscoveryManager**_ where connection is your XMPPConnection.
 Once you have your ServiceDiscoveryManager you will be able to manage the
 supported features. To register a new feature send **addFeature(feature)** to
 your _**ServiceDiscoveryManager**_ where feature is a String that represents
 the supported feature. To remove a supported feature send
 **removeFeature(feature)** to your _**ServiceDiscoveryManager**_ where feature
 is a String that represents the feature to remove.
 **Examples**
 In this example we can see how to add and remove supported features:
 ```
 // Obtain the ServiceDiscoveryManager associated with my XMPP connection
 ServiceDiscoveryManager discoManager = ServiceDiscoveryManager.getInstanceFor(connection);
 // Register that a new feature is supported by this XMPP entity
 discoManager.addFeature(namespace1);
 // Remove the specified feature from the supported features
 discoManager.removeFeature(namespace2);
 ```
 Provide node information
 ------------------------
 **Description**
 Your XMPP entity may receive a discovery request for items non-addressable as
 a JID such as the MUC rooms where you are joined. In order to answer the
 correct information it is necessary to configure the information providers
 associated to the items/nodes within the Smack client.
 **Usage**
 In order to configure the associated nodes within the Smack client you will
 need to create a NodeInformationProvider and register it with the
 _**ServiceDiscoveryManager**_. To get your ServiceDiscoveryManager send
 **getInstanceFor(connection)** to the class _**ServiceDiscoveryManager**_
 where connection is your XMPPConnection.
 Once you have your ServiceDiscoveryManager you will be able to register
 information providers for the XMPP entity's nodes. To register a new node
 information provider send **setNodeInformationProvider(String node,
 NodeInformationProvider listener)** to your _**ServiceDiscoveryManager**_
 where node is the item non-addressable as a JID and listener is the
 _**NodeInformationProvider**_ to register. To unregister a
 _**NodeInformationProvider**_ send **removeNodeInformationProvider(String
 node)** to your _**ServiceDiscoveryManager**_ where node is the item non-
 addressable as a JID whose information provider we want to unregister.
 **Examples**
 In this example we can see how to register a NodeInformationProvider with a
 ServiceDiscoveryManager that will provide information concerning a node named
 "http://jabber.org/protocol/muc#rooms":
 ```
 // Set the NodeInformationProvider that will provide information about the
 // joined rooms whenever a disco request is received
 ServiceDiscoveryManager.getInstanceFor(connection).setNodeInformationProvider(
 	"http://jabber.org/protocol/muc#rooms",
 	new NodeInformationProvider() {
 		public List<DiscoverItems.Item> getNodeItems() {
 			MultiUserChatManager mucManager = MultiUserChatManager.getInstanceFor(connection);
 			List<DiscoverItems.Item> answer = new ArrayList<>();
 			Iterator<Jid> rooms = mucManager.getJoinedRooms().iterator();
 			while (rooms.hasNext()) {
 				answer.add(new DiscoverItems.Item(rooms.next()));
 			}
 			return answer;
 		}
 		public List<String> getNodeFeatures() {...}
 		public List<DiscoverInfo.Identity> getNodeIdentities() {...}
 		public List<ExtensionElement> getNodePacketExtensions() {...}
 });
 ```
 Discover items associated with an XMPP entity
 ---------------------------------------------
 **Description**
 In order to obtain information about a specific item you have to first
 discover the items available in an XMPP entity.
 **Usage**
 Once you have your ServiceDiscoveryManager you will be able to discover items
 associated with an XMPP entity. To discover the items of a given XMPP entity
 send **discoverItems(entityID)** to your _**ServiceDiscoveryManager**_ where
 entityID is the ID of the entity. The message **discoverItems(entityID)** will
 answer an instance of _**DiscoverItems**_ that contains the discovered items.
 **Examples**
 In this example we can see how to discover the items associated with an online
 catalog service:
 ```
 // Obtain the ServiceDiscoveryManager associated with my XMPPConnection
 ServiceDiscoveryManager discoManager = ServiceDiscoveryManager.getInstanceFor(connection);
 // Get the items of a given XMPP entity
 // This example gets the items associated with online catalog service
 DiscoverItems discoItems = discoManager.discoverItems("plays.shakespeare.lit");
 // Get the discovered items of the queried XMPP entity
 Iterator it = discoItems.getItems().iterator();
 // Display the items of the remote XMPP entity
 while (it.hasNext()) {
 	DiscoverItems.Item item = (DiscoverItems.Item) it.next();
 	System.out.println(item.getEntityID());
 	System.out.println(item.getNode());
 	System.out.println(item.getName());
 }
 ```
 Discover information about an XMPP entity
 -----------------------------------------
 **Description**
 Once you have discovered the entity ID and name of an item, you may want to
 find out more about the item. The information desired generally is of two
 kinds: 1) The item's identity and 2) The features offered by the item.
 This information helps you determine what actions are possible with regard to
 this item (registration, search, join, etc.) as well as specific feature types
 of interest, if any (e.g., for the purpose of feature negotiation).
 **Usage**
 Once you have your ServiceDiscoveryManager you will be able to discover
 information associated with an XMPP entity. To discover the information of a
 given XMPP entity send **discoverInfo(entityID)** to your
 _**ServiceDiscoveryManager**_ where entityID is the ID of the entity. The
 message **discoverInfo(entityID)** will answer an instance of
 _**DiscoverInfo**_ that contains the discovered information.
 **Examples**
 In this example we can see how to discover the information of a conference
 room:
 ```
 // Obtain the ServiceDiscoveryManager associated with my XMPPConnection
 ServiceDiscoveryManager discoManager = ServiceDiscoveryManager.getInstanceFor(connection);
 // Get the information of a given XMPP entity
 // This example gets the information of a conference room
 DiscoverInfo discoInfo = discoManager.discoverInfo("balconyscene@plays.shakespeare.lit");
 // Get the discovered identities of the remote XMPP entity
 Iterator it = discoInfo.getIdentities().iterator();
 // Display the identities of the remote XMPP entity
 while (it.hasNext()) {
 	DiscoverInfo.Identity identity = (DiscoverInfo.Identity) it.next();
 	System.out.println(identity.getName());
 	System.out.println(identity.getType());
 	System.out.println(identity.getCategory());
 }
 // Check if room is password protected
 discoInfo.containsFeature("muc_passwordprotected");
 ```
 Publish publicly available items
 --------------------------------
 **Description**
 Publish your entity items to some kind of persistent storage. This enables
 other entities to query that entity using the disco#items namespace and
 receive a result even when the entity being queried is not online (or
 available).
 **Usage**
 Once you have your ServiceDiscoveryManager you will be able to publish items
 to some kind of persistent storage. To publish the items of a given XMPP
 entity you have to first create an instance of _**DiscoverItems**_ and
 configure it with the items to publish. Then you will have to send
 **publishItems(Jid entityID, DiscoverItems discoverItems)** to your
 _**ServiceDiscoveryManager**_ where entityID is the address of the XMPP entity
 that will persist the items and discoverItems contains the items to publish.
 **Examples**
 In this example we can see how to publish new items:
 ```
 // Obtain the ServiceDiscoveryManager associated with my XMPPConnection
 ServiceDiscoveryManager discoManager = ServiceDiscoveryManager.getInstanceFor(connection);
 // Create a DiscoverItems with the items to publish
 DiscoverItems itemsToPublish = new DiscoverItems();
 Jid jid = JidCreate.from("pubsub.shakespeare.lit");
 DiscoverItems.Item itemToPublish = new DiscoverItems.Item(jid);
 itemToPublish.setName("Avatar");
 itemToPublish.setNode("romeo/avatar");
 itemToPublish.setAction(DiscoverItems.Item.UPDATE_ACTION);
 itemsToPublish.addItem(itemToPublish);
 // Publish the new items by sending them to the server
 Jid jid2 = JidCreate.from("host");
 discoManager.publishItems(jid2, itemsToPublish);

 File Transfer
 =============
 [Back](index.md)
 The file transfer extension allows the user to transmit and receive files.
  * Send a file to another user
  * Receiving a file from another user
  * Monitoring the progress of a file transfer
 **XEP related:** [XEP-95](http://www.xmpp.org/extensions/xep-0095.html) [XEP-96](http://www.xmpp.org/extensions/xep-0096.html) [XEP-65](http://www.xmpp.org/extensions/xep-0065.html) [XEP-47](http://www.xmpp.org/extensions/xep-0047.html)
 Send a file to another user
 ---------------------------
 **Description**
 A user may wish to send a file to another user. The other user has the option
 of accepting, rejecting, or ignoring the users request. Smack provides a
 simple interface in order to enable the user to easily send a file.
 **Usage**
 In order to send a file you must first construct an instance of the
 **_FileTransferManager_** class. In order to instantiate the manager
 you should call _FileTransferManager.getInstanceFor(connection)_, where connection is an XMPPConnection instance.
 Once you have your **_FileTransferManager_** you will need to create an
 outgoing file transfer to send a file. The method to use on the
 **_FileTransferManager_** is the **createOutgoingFileTransfer(userID)**
 method. The userID you provide to this method is the fully-qualified jabber ID
 of the user you wish to send the file to. A fully-qualified jabber ID consists
 of a node, a domain, and a resource. The user must be connected to the
 resource in order to be able to receive the file transfer.
 Now that you have your **_OutgoingFileTransfer_** instance you will want to
 send the file. The method to send a file is **sendFile(file, description)**.
 The file you provide to this method should be a readable file on the local
 file system, and the description is a short description of the file to help
 the user decide whether or not they would like to recieve the file.
 For information on monitoring the progress of a file transfer see the
 monitoring progress section of this document.
 Other means to send a file are also provided as part of the
 **_OutgoingFileTransfer_**. Please consult the Javadoc for more information.
 **Examples**
 In this example we can see how to send a file:
 ```
 // Create the file transfer manager
 FileTransferManager manager = FileTransferManager.getInstanceFor(connection);
 // Create the outgoing file transfer
 OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer(entityFullJid);
 // Send the file
 transfer.sendFile(new File("shakespeare_complete_works.txt"), "You won't believe this!");
 ```
 Receiving a file from another user
 ----------------------------------
 **Description**
 The user may wish to receive files from another user. The process of receiving
 a file is event driven, new file transfer requests are received from other
 users via a listener registered with the file transfer manager.
 **Usage**
 In order to receive a file you must first construct an instance of the
 **_FileTransferManager_** class. This class has one static factory method with one
 parameter which is your XMPPConnection. In order to instantiate the manager
 you should call _FileTransferManager.getInstanceFor(connection)_.
 Once you have your **_FileTransferManager_** you will need to register a
 listener with it. The FileTransferListener interface has one method,
 **fileTransferRequest(request)**. When a request is received through this
 method, you can either accept or reject the request. To help you make your
 decision there are several methods in the **_FileTransferRequest_** class that
 return information about the transfer request.
 To accept the file transfer, call the **accept()** method. This method will create an
 **_IncomingFileTransfer_**. After you have the file transfer you may start to
 transfer the file by calling the **recieveFile(file)** method. The file
 provided to this method will be where the data from the file transfer is saved.
 Finally, to reject the file transfer the only method you need to call is
 **reject()** on the **_FileTransferRequest_**.
 For information on monitoring the progress of a file transfer see the
 monitoring progress section of this document.
 Other means to receive a file are also provided as part of the
 **_IncomingFileTransfer_**. Please consult the Javadoc for more information.
 **Examples**
 In this example we can see how to approve or reject a file transfer request:
 ```
 // Create the file transfer manager
 final FileTransferManager manager = FileTransferManager.getInstanceFor(connection);
 // Create the listener
 manager.addFileTransferListener(new FileTransferListener() {
 	public void fileTransferRequest(FileTransferRequest request) {
 	// Check to see if the request should be accepted
 	if (shouldAccept(request)) {
 		// Accept it
 		IncomingFileTransfer transfer = request.accept();
 		transfer.recieveFile(new File("shakespeare_complete_works.txt"));
 	} else {
 		// Reject it
 		request.reject();
 	}
 }
 });
 ```
 Monitoring the progress of a file transfer
 ------------------------------------------
 **Description**
 While a file transfer is in progress you may wish to monitor the progress of a
 file transfer.
 **Usage**
 Both the **_IncomingFileTransfer_** and the **_OutgoingFileTransfer_** extend
 the **_FileTransfer_** class which provides several methods to monitor how a
 file transfer is progressing:
  * **getStatus()** - The file transfer can be in several states, negotiating, rejected, cancelled, in progress, error, and complete. This method will return which state the file transfer is currently in. 
  * **getProgress()** - If the status of the file transfer is in progress this method will return a number between 0 and 1, 0 being the transfer has not yet started and 1 being the transfer is complete. It may also return a -1 if the transfer is not in progress. 
  * **isDone()** - Similar to getProgress() except it returns a _boolean_. If the state is rejected, canceled, error, or complete then true will be returned and false otherwise. 
  * **getError()** - If there is an error during the file transfer this method will return the type of error that occured.
  **Examples**
 In this example we can see how to monitor a file transfer:
 ```
 while(!transfer.isDone()) {
 	if (transfer.getStatus().equals(Status.error)) {
 		System.out.println("ERROR!!! " + transfer.getError());
 	} else {
 		System.out.println(transfer.getStatus());
 		System.out.println(transfer.getProgress());
 	}
 	sleep(1000);
 }

 HTTP over XMPP transport
 ========================
 [Back](index.md)
 Allows the transport of HTTP communication over XMPP peer-to-peer networks.
  * Discover HOXT support
  * IQ exchange
 Discover HOXT support
 ---------------------
 **Description**
 Before using this extension you must ensure that your counterpart supports it
 also.
 **Usage**
 Once you have your _**ServiceDiscoveryManager**_ you will be able to discover
 information associated with an XMPP entity. To discover the information of a
 given XMPP entity send **discoverInfo(entityID)** to your
 _**ServiceDiscoveryManager**_ where entityID is the ID of the entity. The
 message **discoverInfo(entityID)** will answer with an instance of
 _**DiscoverInfo**_ that contains the discovered information.
 **Examples**
 In this example we can see how to check if the counterpart supports HOXT:
 ```
 // Obtain the ServiceDiscoveryManager associated with my XMPPConnection
 ServiceDiscoveryManager discoManager = ServiceDiscoveryManager.getInstanceFor(connection);
 // Get the information of a given XMPP entity, where entityID is a Jid
 DiscoverInfo discoInfo = discoManager.discoverInfo(entityID);
 // Check if room is HOXT is supported
 boolean isSupported = discoInfo.containsFeature("urn:xmpp:http");
 ```
 IQ exchange
 -----------
 **Description**
 You can use IQ's to perform HTTP requests and responses. This is applicable to
 relatively short requests and responses (due to the limitation of XMPP message
 size).
 **Usage**
 First you need to register a _**StanzaListener**_ to be able to handle
 intended IQs.
 For the HTTP client you:
  * You create and send _**HttpOverXmppReq**_ request.
  * Then you handle the _**HttpOverXmppResp**_ response in your _**StanzaListener**_.
 For the HTTP server you:
  * You handle the _**HttpOverXmppReq**_ requests in your _**StanzaListener**_.
  * And create and send _**HttpOverXmppResp**_ responses.
 **Examples**
 In this example we are an HTTP client, so we send a request (POST) and handle the
 response:
 ```
 // create a request body
 String urlEncodedMessage = "I_love_you";
 // prepare headers
 List<Header> headers = new ArrayList<>();
 headers.add(new Header("Host", "juliet.capulet.com"));
 headers.add(new Header("Content-Type", "application/x-www-form-urlencoded"));
 headers.add(new Header("Content-Length", Integer.toString(urlEncodedMessage.length())));
 // provide body or request (not mandatory, - empty body is used for GET)
 AbstractHttpOverXmpp.Text child = new AbstractHttpOverXmpp.Text(urlEncodedMessage);
 AbstractHttpOverXmpp.Data data = new AbstractHttpOverXmpp.Data(child);
 // create request
 HttpOverXmppReq req = HttpOverXmppReq.buider()
 							.setMethod(HttpMethod.POST)
 							.setResource("/mailbox")
 							.setHeaders(headers)
 							.setVersion("1.1")
 							.setData(data)
 							.build();
 // add to, where jid is the Jid of the individual the packet is sent to
 req.setTo(jid);
 // send it
 connection.sendIqWithResponseCallback(req, new StanzaListener() {
   public void processStanza(Stanza iq) {
 		HttpOverXmppResp resp = (HttpOverXmppResp) iq;
 		// check HTTP response code
 		if (resp.getStatusCode() == 200) {
 			// get content of the response
 			NamedElement child = resp.getData().getChild();
 			// check which type of content of the response arrived
 			if (child instanceof AbstractHttpOverXmpp.Xml) {
 				// print the message and anxiously read if from the console ;)
 				System.out.println(((AbstractHttpOverXmpp.Xml) child).getText());
 			} else {
 				// process other AbstractHttpOverXmpp data child subtypes
 			}
 		}
 	}
 });

 Group Chat Invitations
 ======================
 [Back](index.md)
 The group chat invitation extension is used to invite other users to a
 group chat room.
  * Inviting Other Users
  * Listen for Invitations
 **XEP related:** N/A -- this protocol is outdated now that the Multi-User Chat (MUC) XEP is available ([XEP-45](http://www.xmpp.org/extensions/xep-0045.html)). However, most existing clients still use this older protocol. Once MUC support becomes more widespread, this API may be deprecated. 
 Inviting Other Users
 --------------------
 To use the GroupChatInvitation packet extension to invite another user to a
 group chat room, address a new message to the user and set the room name
 appropriately, as in the following code example:
 ```
 Message message = new Message("user@chat.example.com", "Join me for a group chat!");
 message.addExtension(new GroupChatInvitation("room@chat.example.com"));
 con.sendStanza(message);
 ```
 The XML generated for the invitation portion of the code above would be:
 ```
 <x xmlns="jabber:x:conference" jid="room@chat.example.com"/>
 ```
 Listening for Invitations
 -------------------------
 To listen for group chat invitations, use a StanzaExtensionFilter for the `x`
 element name and `jabber:x:conference` namespace, as in the following code
 example:
 ```
 StanzaFilter filter = new StanzaExtensionFilter("x", "jabber:x:conference");
 // Create a packet collector or packet listeners using the filter...

 Internet of Things (XEP-0323, -0324, -0325, -0347)
 ==================================================
 [Back](index.md)
 The Internet of Things (IoT) XEPs are an experimental open standard how XMPP can be used for IoT. They currently consists of
 - XEP-0323 Sensor Data
 - XEP-0324 Provisioning
 - XEP-0325 Control
 - XEP-0326 Concentrators
 - XEP-0347 Discovery
 Smack only supports a subset of the functionality described by the XEPs!
 Thing Builder
 -------------
 The `org.jivesoftware.smackx.iot.Thing` class acts as basic entity representing a single "Thing" which can be used to retrieve data from or to send control commands to. `Things` are constructed using a builder API.
 Reading data from things
 ------------------------
 For example, we can build a Thing which provides the current temperature with
 ```java
 Thing dataThing = Thing.builder().setKey(key).setSerialNumber(sn).setMomentaryReadOutRequestHandler(new ThingMomentaryReadOutRequest() {
    @Override
    public void momentaryReadOutRequest(ThingMomentaryReadOutResult callback) {
        int temp = getCurrentTemperature();
        IoTDataField.IntField field = new IntField("temperature", temp);
        callback.momentaryReadOut(Collections.singletonList(field));
    }
 }).build();
 ```
 While not strictly required, most things are identified via a key and serial number. We also build the thing with a "momentary read out request handler" which when triggered, retrieves the current temperature and reports it back to the requestor.
 After the `Thing` is built, it needs to be made available so that other entities within the federated XMPP network can use it. Right now we only install the Thing in the `IoTDataManager`, which means the thing will act on read out requests but not be managed by a provisioning server.
 ```java
 IoTDataManager iotDataManager = IoTDataManager.getInstanceFor(connection);
 iotDataManager.installThing(thing);
 ```
 The data can be read out also by using the `IoTDataManager`:
 ```java
 FullJid jid = …
 List<IoTFieldsExtension> values = iotDataManager.requestMomentaryValuesReadOut(jid);
 ```
 Now you have to unwrap the `IoTDataField` instances from the `IoTFieldsExtension`. Note that Smack currently only supports a subset of the specified data types.
 Controlling a thing
 -------------------
 Things can also be controlled, e.g. to turn on a light. Let's create a thing which can be used to turn the light on and off.
 ```java
 Thing controlThing = Thing.builder().setKey(key).setSerialNumber(sn).setControlRequestHandler(new ThingControlRequest() {
    @Override
    public void processRequest(Jid from, Collection<SetData> setData) throws XMPPErrorException {
        for (final SetData data : setData) {
            if (!data.getName().equals("light")) continue;
            if (!(data instanceof SetBoolData)) continue;
            SetBoolData boolData = (SetBoolData) data;
            setLight(boolData.getBooleanValue());
        }
    }
 }).build();
 ```
 Now we have to install this thing into the `IoTControlManager`:
 ```java
 IoTControlManager iotControlManager = IoTControlManager.getInstanceFor(connection);
 iotControlManager.installThing(thing);
 ```
 The `IoTControlManager` can also be used to control a thing:
 ```java
 FullJid jid = …
 SetData setData = new SetBoolData("light", true);
 iotControlManager.setUsingIq(jid, setData);
 ```
 Smack currently only supports a subset of the possible data types for set data.
 Discovery
 ---------
 You may have wondered how a full JIDs of things can be determined. One approach is using the discovery mechanisms specified in XEP-0347. Smack provides the `IoTDiscoveryManager` as an API for this.
 For example, instead of just installing the previous things in the `IoTDataManager` and/or `IoTControlManager`, we could also use the `IoTDiscoveryManger` to register the thing with a registry. Doing this also installs the thing in the `IoTDataManager` and the `IoTControlManager`.
 ```java
 IoTDiscoveryManager iotDiscoveryManager = IoTDiscoveryManager.getInstanceFor(connection);
 iotDiscovyerManager.registerThing(thing);
 ```
 The registry will now make the thing known to a broader audience, and available for a potential owner.
 The `IoTDiscoveryManager` can also be used to claim, disown, remove and unregister a thing.
 Provisioning
 ------------
 Things can usually only be used by other things if they are friends. Since a thing normally can't decide on its own if an incoming friendship request should be granted or not, we can delegate this decision to a provisioning service. Smack provides the `IoTProvisinoManager` to deal with friendship and provisioning.
 For example, if you want to befriend another thing:
 ```java
 BareJid jid = …
 IoTProvisioningManager iotProvisioningManager = IoTProvisioningManager.getInstanceFor(connection);
 iotProvisioningManager.sendFriendshipRequest(jid);
 ```

 Message Markup
 ==============
 [Back](index.md)
 [Message Markup (XEP-0394)](https://xmpp.org/extensions/xep-0394.html) can be used as an alternative to XHTML-IM to style messages, while keeping the body and markup information strictly separated.
 This implementation can *not* be used to render message bodies, but will offer a simple to use interface for creating ExtensionElements which encode the markup information.
 ## Usage
 The most important class is the `MarkupElement` class, which contains a Builder.
 To start creating a Message Markup Extension, call `MarkupElement.getBuilder()`.
 (Almost) all method calls documented below will be made on the builder.
 Whenever a method call receives a `start` and `end` index, `start` represents the first character, which is affected by the styling, while `end` is the character *after* the last affected character.
 ### Inline styling
 Currently there are 3 styles available:
 * *emphasis*, which should be rendered by a client as *italic*, or **bold**
 * *code*, which should be rendered in `monospace`
 * *deleted*, which should be rendered as ~~strikethrough~~.
 Those styles are available by calling `builder.setEmphasis(int start, int end)`,
 `builder.setDeleted(int start, int end)` and `builder.setCode(int start, int end)`.
 If you want to apply multiple inline styles to a section, you can do the following:
 ```
 Set<SpanElement.SpanStyle> spanStyles = new HashSet<>();
 styles.add(SpanElement.SpanStyle.emphasis);
 styles.add(SpanElement.SpanStyle.deleted);
 builder.addSpan(start, end, spanStyles);
 ```
 Note, that spans cannot overlap one another.
 ### Block Level Styling
 Available block level styles are:
 * Code blocks, which should be rendered as
 ```
 blocks
 of
 code
 ```
 * Itemized lists, which should render as
  * Lists
  * with possibly multiple
  * entries
 * Block Quotes, which should be rendered by the client
  > as quotes, which
  >> also can be nested
 To mark a section as code block, call `builder.setCodeBlock(start, end)`.
 To create a list, call `MarkupElement.Builder.ListBuilder lbuilder = builder.beginList()`, which will return a list builder.
 On this you can call `lbuilder.addEntry(start, end)` to add an entry.
 Note: If you add an entry, the start value MUST be equal to the end value of the previous added entry!
 To end the list, call `lbuilder.endList()`, which will return the MessageElement builder.
 To create a block quote, call `builder.setBlockQuote(start, end)`.
 Note that block level elements MUST NOT overlap each other boundaries, but may be fully contained (nested) within each other.

 For all examples in this document, assume that the following variables exists:
 ```java
 // Create the XMPP address (JID) of the MUC.
 EntityBareJid mucJid = JidCreate.bareFrom("myroom@conference.jabber.org");
 // Create the nickname.
 Resourcepart nickname = Resourcepart.from("testbot");
 // A other use (we may invite him to a MUC).
 FullJid otherJid = JidCreate.fullFrom("user3@host.org/Smack");
 ```
 Create a new Room
 -----------------
 **Description**
 Allowed users may create new rooms. There are two types of rooms that you can
 create. **Instant rooms** which are available for immediate access and are
 automatically created based on some default configuration and **Reserved
 rooms** which are manually configured by the room creator before anyone is
 allowed to enter.
 **Usage**
 In order to create a room you will need to first create an instance of
 _**MultiUserChat**_.
 In order to do so, get a instance of `MultiUserChatManager` and call `getMultiUserChat(String)` to retrieve a `MultiUserChat` instance.
 The next step is to send **create(String nickname)** to
 the _**MultiUserChat**_ instance where nickname is the nickname to use when
 joining the room.
 Depending on the type of room that you want to create you will have to use
 different configuration forms. In order to create an Instant room just use
 `MucCreateConfigFormHandle.makeInstant()`. But if you
 want to create a Reserved room then you should first get the room's
 configuration form, complete the form and finally send it back to the server.
 **Examples**
 In this example we can see how to create an instant room:
 ```java
 // Get the MultiUserChatManager
 MultiUserChatManager manager = MultiUserChatManager.getInstanceFor(connection);
 // Get a MultiUserChat using MultiUserChatManager
 MultiUserChat muc = manager.getMultiUserChat(mucJid);
 // Create the room and send an empty configuration form to make this an instant room
 muc.create(nickname).makeInstant();
 ```
 In this example we can see how to create a reserved room. The form is
 completed with default values:
 ```java
 // Get the MultiUserChatManager
 MultiUserChatManager manager = MultiUserChatManager.getInstanceFor(connection);
 // Create a MultiUserChat using an XMPPConnection for a room
 MultiUserChat muc = manager.getMultiUserChat(mucJid);
 // Prepare a list of owners of the new room
 Set<Jid> owners = JidUtil.jidSetFrom(new String[] { "me@example.org", "juliet@example.org" });
 // Create the room
 muc.create(nickname)
  .getConfigFormManger()
  .setRoomOwners(owners)
  .submitConfigurationForm();
 ```
 Join a room
 -----------
 **Description**
 Your usual first step in order to send messages to a room is to join the room.
 Multi User Chat allows to specify several parameter while joining a room.
 Basically you can control the amount of history to receive after joining the
 room as well as provide your nickname within the room and a password if the
 room is password protected.
 **Usage**
 In order to join a room you will need to first get an instance of
 _**MultiUserChat**_.
 In order to do so, get a instance of `MultiUserChatManager` and call `getMultiUserChat(String)` to retrieve a `MultiUserChat` instance.
 The next step is to send **join(...)** to the
 _**MultiUserChat**_ instance. But first you will have to decide which join
 message to send. If you want to just join the room without a password and
 without specifying the amount of history to receive then you could use
 **join(String nickname)** where nickname if your nickname in the room. In case
 the room requires a password in order to join you could then use **join(String
 nickname, String password)**. And finally, the most complete way to join a
 room is to send **join(String nickname, String password, DiscussionHistory
 history, long timeout)** where nickname is your nickname in the room, ,
 password is your password to join the room, history is an object that
 specifies the amount of history to receive and timeout is the milliseconds to
 wait for a response from the server.
 **Examples**
 In this example we can see how to join a room with a given nickname:
 ```java
 // Get the MultiUserChatManager
 MultiUserChatManager manager = MultiUserChatManager.getInstanceFor(connection);
 // Create a MultiUserChat using an XMPPConnection for a room
 MultiUserChat muc2 = manager.getMultiUserChat(mucJid);
 // User2 joins the new room
 // The room service will decide the amount of history to send
 muc2.join(nickname);
 ```
 In this example we can see how to join a room with a given nickname and
 password:
 ```java
 // Get the MultiUserChatManager
 MultiUserChatManager manager = MultiUserChatManager.getInstanceFor(connection);
 // Create a MultiUserChat using an XMPPConnection for a room
 MultiUserChat muc2 = manager.getMultiUserChat(mucJid);
 // User2 joins the new room using a password
 // The room service will decide the amount of history to send
 muc2.join(nickname, "password");
 ```
 In this example we can see how to join a room with a given nickname specifying
 the amount of history to receive:
 ```java
 // Get the MultiUserChatManager
 MultiUserChatManager manager = MultiUserChatManager.getInstanceFor(connection);
 // Create a MultiUserChat using an XMPPConnection for a room
 MultiUserChat muc2 = manager.getMultiUserChat(mucJid);
 // User2 joins the new room using a password and specifying
 // the amount of history to receive. In this example we are requesting the last 5 messages.
 DiscussionHistory history = new DiscussionHistory();
 history.setMaxStanzas(5);
 muc2.join(nickname, "password", history, conn1.getPacketReplyTimeout());
 ```
 Manage room invitations
 -----------------------
 **Description**
 It can be useful to invite another user to a room in which one is an occupant.
 Depending on the room's type the invitee could receive a password to use to
 join the room and/or be added to the member list if the room is of type
 members-only. Smack allows to send room invitations and let potential invitees
 to listening for room invitations and inviters to listen for invitees'
 rejections.
 **Usage**
 In order to invite another user to a room you must be already joined to the
 room. Once you are joined just send **invite(String participant, String
 reason)** to the _**MultiUserChat**_ where participant is the user to invite
 to the room (e.g. hecate@shakespeare.lit) and reason is the reason why the
 user is being invited.
 If potential invitees want to listen for room invitations then the invitee
 must add an _**InvitationListener**_ to the _**MultiUserChatManager**_ class. Since
 the _**InvitationListener**_ is an _interface_, it is necessary to create a
 class that implements this _interface_. If an inviter wants to listen for room
 invitation rejections, just add an _**InvitationRejectionListener**_ to the
 _**MultiUserChat**_. _**InvitationRejectionListener**_ is also an interface so
 you will need to create a class that implements this interface.
 **Examples**
 In this example we can see how to invite another user to the room and lister
 for possible rejections:
 ```java
 // Get the MultiUserChatManager
 MultiUserChatManager manager = MultiUserChatManager.getInstanceFor(connection);
 // Create a MultiUserChat using an XMPPConnection for a room
 MultiUserChat muc2 = manager.getMultiUserChat(mucJid);
 muc2.join(nickname);
 // User2 listens for invitation rejections
 muc2.addInvitationRejectionListener(new InvitationRejectionListener() {
 	public void invitationDeclined(String invitee, String reason) {
 		// Do whatever you need here...
 	}
 });
 // User2 invites user3 to join to the room
 muc2.invite(otherJid, "Meet me in this excellent room");
 ```
 In this example we can see how to listen for room invitations and decline
 invitations:
 ```java
 // User3 listens for MUC invitations
 MultiUserChatManager.getInstanceFor(connection).addInvitationListener(new InvitationListener() {
 	public void invitationReceived(XMPPConnection conn, String room, EntityFullJid inviter, String reason, String password) {
 		// Reject the invitation
 		MultiUserChat.decline(conn, room, inviter.asBareJid()s, "I'm busy right now");
 	}
 });
 ```
 Discover MUC support
 --------------------
 **Description**
 A user may want to discover if one of the user's contacts supports the Multi-
 User Chat protocol.
 **Usage**
 In order to discover if one of the user's contacts supports MUC just send
 **isServiceEnabled(String user)** to the
 _**MultiUserChatManager**_ class where user is a fully qualified XMPP ID, e.g.
 jdoe@example.com. You will receive a boolean indicating whether the user
 supports MUC or not.
 **Examples**
 In this example we can see how to discover support of MUC:
 ```java
 // Discover whether user3@host.org supports MUC or not
 boolean supports = MultiUserChatManager.getInstanceFor(connection).isServiceEnabled(otherJid);
 ```
 Discover joined rooms
 ---------------------
 **Description**
 A user may also want to query a contact regarding which rooms the contact is
 in.
 **Usage**
 In order to get the rooms where a user is in just send
 **getJoinedRooms(String user)** to the
 _**MultiUserChatManager**_ class where user is a fully qualified XMPP ID, e.g.
 jdoe@example.com. You will get an Iterator of Strings as an answer where each
 String represents a room name.
 **Examples**
 In this example we can see how to get the rooms where a user is in:
 ```java
 // Get the MultiUserChatManager
 MultiUserChatManager manager = MultiUserChatManager.getInstanceFor(connection);
 // Get the rooms where user3@host.org has joined
 List<String> joinedRooms = manager.getJoinedRooms("user3@host.org/Smack");
 ```
 Discover room information
 -------------------------
 **Description**
 A user may need to discover information about a room without having to
 actually join the room. The server will provide information only for public
 rooms.
 **Usage**
 In order to discover information about a room just send
 **getRoomInfo(String room)** to the
 _**MultiUserChatManager**_ class where room is the XMPP ID of the room, e.g.
 roomName@conference.myserver. You will get a RoomInfo object that contains the
 discovered room information.
 **Examples**
 In this example we can see how to discover information about a room:
 ```java
 // Get the MultiUserChatManager
 MultiUserChatManager manager = MultiUserChatManager.getInstanceFor(connection);
 // Discover information about the room roomName@conference.myserver
 RoomInfo info = manager.getRoomInfo("roomName@conference.myserver");
 System.out.println("Number of occupants:" + info.getOccupantsCount());
 System.out.println("Room Subject:" + info.getSubject());
 ```
 Start a private chat
 --------------------
 **Description**
 A room occupant may want to start a private chat with another room occupant
 even though they don't know the fully qualified XMPP ID (e.g.
 jdoe@example.com) of each other.
 **Usage**
 To create a private chat with another room occupant just send
 **createPrivateChat(String participant)** to the _**MultiUserChat**_ that you
 used to join the room. The parameter participant is the occupant unique room
 JID (e.g. 'darkcave@macbeth.shakespeare.lit/Paul'). You will receive a regular
 _**Chat**_ object that you can use to chat with the other room occupant.
 **Examples**
 In this example we can see how to start a private chat with another room
 occupant:
 ```
 // Start a private chat with another participant
 Chat chat = muc2.createPrivateChat("myroom@conference.jabber.org/johndoe");
 chat.sendMessage("Hello there");
 ```
 Manage changes on room subject
 ------------------------------
 **Description**
 A common feature of multi-user chat rooms is the ability to change the subject
 within the room. As a default, only users with a role of "moderator" are
 allowed to change the subject in a room. Although some rooms may be configured
 to allow a mere participant or even a visitor to change the subject.
 Every time the room's subject is changed you may want to be notified of the
 modification. The new subject could be used to display an in-room message.
 **Usage**
 In order to modify the room's subject just send **changeSubject(String
 subject)** to the _**MultiUserChat**_ that you used to join the room where
 subject is the new room's subject. On the other hand, if you want to be
 notified whenever the room's subject is modified you should add a
 _**SubjectUpdatedListener**_ to the _**MultiUserChat**_ by sending
 **addSubjectUpdatedListener(SubjectUpdatedListener listener)** to the
 _**MultiUserChat**_. Since the _**SubjectUpdatedListener**_ is an _interface_,
 it is necessary to create a class that implements this _interface_.
 **Examples**
 In this example we can see how to change the room's subject and react whenever
 the room's subject is modified:
 ```
 // An occupant wants to be notified every time the room's subject is changed
 muc3.addSubjectUpdatedListener(new SubjectUpdatedListener() {
 	public void subjectUpdated(String subject, String from) {
 		....
 	}
 });
 // A room's owner changes the room's subject
 muc2.changeSubject("New Subject");
 ```
 Manage role modifications
 -------------------------
 **Description**
 There are four defined roles that an occupant can have:
  1. Moderator
  2. Participant
  3. Visitor
  4. None (the absence of a role)
 These roles are temporary in that they do not persist across a user's visits
 to the room and can change during the course of an occupant's visit to the
 room.
 A moderator is the most powerful occupant within the context of the room, and
 can to some extent manage other occupants' roles in the room. A participant
 has fewer privileges than a moderator, although he or she always has the right
 to speak. A visitor is a more restricted role within the context of a
 moderated room, since visitors are not allowed to send messages to all
 occupants.
 Roles are granted, revoked, and maintained based on the occupant's room
 nickname or full JID. Whenever an occupant's role is changed Smack will
 trigger specific events.
 **Usage**
 In order to grant voice (i.e. make someone a _participant_) just send the
 message **grantVoice(String nickname)** to _**MultiUserChat**_. Use
 **revokeVoice(String nickname)** to revoke the occupant's voice (i.e. make the
 occupant a _visitor_).
 In order to grant moderator privileges to a participant or visitor just send
 the message **grantModerator(String nickname)** to _**MultiUserChat**_. Use
 **revokeModerator(String nickname)** to revoke the moderator privilege from
 the occupant thus making the occupant a participant.
 Smack allows you to listen for role modification events. If you are interested
 in listening role modification events of any occupant then use the listener
 **_ParticipantStatusListener_**. But if you are interested in listening for
 your own role modification events, use the listener **_UserStatusListener_**.
 Both listeners should be added to the _**MultiUserChat**_ by using
 **addParticipantStatusListener(ParticipantStatusListener listener)** or
 **addUserStatusListener(UserStatusListener listener)** respectively. These
 listeners include several notification events but you may be interested in
 just a few of them. Smack provides default implementations for these listeners
 avoiding you to implement all the interfaces' methods. The default
 implementations are **_DefaultUserStatusListener_** and
 **_DefaultParticipantStatusListener_**. Below you will find the sent messages
 to the listeners whenever an occupant's role has changed.
 These are the triggered events when the role has been upgraded:
 | Old | New | Events |
 |-----|-----|--------|
 | None | Visitor | -- |
 | Visitor | Participant | voiceGranted |
 | Participant | Moderator | moderatorGranted |
 | None | Participant | voiceGranted |
 | None | Moderator | voiceGranted + moderatorGranted |
 | Visitor | Moderator | voiceGranted + moderatorGranted |
 These are the triggered events when the role has been downgraded:
 | Old | New | Events |
 |-----|-----|--------|
 | Moderator | Participant | moderatorRevoked |
 | Participant | Visitor | voiceRevoked |
 | Visitor | None | kicked |
 | Moderator | Visitor | voiceRevoked + moderatorRevoked |
 | Moderator | None | kicked |
 | Participant | None | kicked |
 **Examples**
 In this example we can see how to grant voice to a visitor and listen for the
 notification events:
 ```java
 // User1 creates a room
 muc = manager.getMultiUserChat("myroom@conference.jabber.org");
 muc.create("testbot");
 // User1 (which is the room owner) configures the room as a moderated room
 Form form = muc.getConfigurationForm();
 FillableForm answerForm = configForm.getFillableForm();
 answerForm.setAnswer("muc#roomconfig_moderatedroom", "1");
 muc.sendConfigurationForm(answerForm);
 // User2 joins the new room (as a visitor)
 MultiUserChat muc2 = manager2.getMultiUserChat("myroom@conference.jabber.org");
 muc2.join("testbot2");
 // User2 will listen for his own "voice" notification events
 muc2.addUserStatusListener(new DefaultUserStatusListener() {
 	public void voiceGranted() {
 		super.voiceGranted();
 		...
 	}
 	public void voiceRevoked() {
 		super.voiceRevoked();
 		...
 	}
 });
 // User3 joins the new room (as a visitor)
 MultiUserChat muc3 = manager3.getMultiUserChat("myroom@conference.jabber.org");
 muc3.join("testbot3");
 // User3 will lister for other occupants "voice" notification events
 muc3.addParticipantStatusListener(new DefaultParticipantStatusListener() {
 	public void voiceGranted(String participant) {
 		super.voiceGranted(participant);
 		...
 	}
 	public void voiceRevoked(String participant) {
 		super.voiceRevoked(participant);
 		...
 	}
 });
 // The room's owner grants voice to user2
 muc.grantVoice("testbot2");
 ```
 Manage affiliation modifications
 --------------------------------
 **Description**
 There are five defined affiliations that a user can have in relation to a
 room:
  1. Owner
  2. Admin
  3. Member
  4. Outcast
  5. None (the absence of an affiliation)
 These affiliations are semi-permanent in that they persist across a user's
 visits to the room and are not affected by happenings in the room.
 Affiliations are granted, revoked, and maintained based on the user's bare
 JID.
 If a user without a defined affiliation enters a room, the user's affiliation
 is defined as "none"; however, this affiliation does not persist across
 visits.
 Owners and admins are by definition immune from certain actions. Specifically,
 an owner or admin cannot be kicked from a room and cannot be banned from a
 room. An admin must first lose his or her affiliation (i.e., have an
 affiliation of "none" or "member") before such actions could be performed on
 them.
 The member affiliation provides a way for a room owner or admin to specify a
 "whitelist" of users who are allowed to enter a members-only room. When a
 member enters a members-only room, his or her affiliation does not change, no
 matter what his or her role is. The member affiliation also provides a way for
 users to effectively register with an open room and thus be permanently
 associated with that room in some way (one result may be that the user's
 nickname is reserved in the room).
 An outcast is a user who has been banned from a room and who is not allowed to
 enter the room. Whenever a user's affiliation is changed Smack will trigger
 specific events.
 **Usage**
 In order to grant membership to a room, administrator privileges or owner
 priveliges just send **grantMembership(String jid)**, **grantAdmin(String
 jid)** or **grantOwnership(String jid)** to _**MultiUserChat**_ respectively.
 Use **revokeMembership(String jid)**, **revokeAdmin(String jid)** or
 **revokeOwnership(String jid)** to revoke the membership to a room,
 administrator privileges or owner priveliges respectively.
 In order to ban a user from the room just send the message **banUser(String
 jid, String reason)** to _**MultiUserChat**_.
 Smack allows you to listen for affiliation modification events. If you are
 interested in listening affiliation modification events of any user then use
 the listener **_ParticipantStatusListener_**. But if you are interested in
 listening for your own affiliation modification events, use the listener
 **_UserStatusListener_**. Both listeners should be added to the
 _**MultiUserChat**_ by using
 **addParticipantStatusListener(ParticipantStatusListener listener)** or
 **addUserStatusListener(UserStatusListener listener)** respectively. These
 listeners include several notification events but you may be interested in
 just a few of them. Smack provides default implementations for these listeners
 avoiding you to implement all the interfaces' methods. The default
 implementations are **_DefaultUserStatusListener_** and
 **_DefaultParticipantStatusListener_**. Below you will find the sent messages
 to the listeners whenever a user's affiliation has changed.
 These are the triggered events when the affiliation has been upgraded:
 | Old | New | Events |
 |-----|-----|--------|
 | None | Member | membershipGranted |
 | Member | Admin | membershipRevoked + adminGranted |
 | Admin | Owner | adminRevoked + ownershipGranted |
 | None | Admin | adminGranted |
 | None | Owner | ownershipGranted |
 | Member | Owner | membershipRevoked + ownershipGranted |
 These are the triggered events when the affiliation has been downgraded:
 | Old | New | Events |
 |-----|-----|--------|
 | Owner | Admin | ownershipRevoked + adminGranted |
 | Admin | Member | adminRevoked + membershipGranted |
 | Member | None | membershipRevoked |
 | Owner | Member | ownershipRevoked + membershipGranted |
 | Owner | None | ownershipRevoked |
 | Admin | None | adminRevoked |
 | _Anyone_ | Outcast | banned |
 **Examples**
 In this example we can see how to grant admin privileges to a user and listen
 for the notification events:
 ```java
 // User1 creates a room
 muc = manager.getMultiUserChat("myroom@conference.jabber.org");
 muc.create("testbot");
 // User1 (which is the room owner) configures the room as a moderated room
 Form form = muc.getConfigurationForm();
 FillableForm answerForm = configForm.getFillableForm();
 answerForm.setAnswer("muc#roomconfig_moderatedroom", "1");
 muc.sendConfigurationForm(answerForm);
 // User2 joins the new room (as a visitor)
 MultiUserChat muc2 = manager2.getMultiUserChat("myroom@conference.jabber.org");
 muc2.join("testbot2");
 // User2 will listen for his own admin privileges
 muc2.addUserStatusListener(new DefaultUserStatusListener() {
 	public void membershipRevoked() {
 		super.membershipRevoked();
 		...
 	}
 	public void adminGranted() {
 		super.adminGranted();
 		...
 	}
 });
 // User3 joins the new room (as a visitor)
 MultiUserChat muc3 = manager3.getMultiUserChat("myroom@conference.jabber.org");
 muc3.join("testbot3");
 // User3 will lister for other users admin privileges
 muc3.addParticipantStatusListener(new DefaultParticipantStatusListener() {
 	public void membershipRevoked(String participant) {
 		super.membershipRevoked(participant);
 		...
 	}
 	public void adminGranted(String participant) {
 		super.adminGranted(participant);
 		...
 	}
 });
 // The room's owner grants admin privileges to user2
 muc.grantAdmin("user2@jabber.org");

 Encrypting messages with OMEMO
 ==============================
 [Back](index.md)
 About OMEMO
 -----------
 OMEMO ([XEP-0384](https://xmpp.org/extensions/xep-0384.html)) is an adaption
 of the Signal protocol for XMPP. It provides an important set of
 cryptographic properties including but not restricted to
 * Confidentiality
 * Integrity
 * Authenticity
 * Forward secrecy
 * Future secrecy (break-in recovery)
 * Plausible deniability
 Contrary to OTR it is capable of multi-end-to-multi-end encryption and
 message synchronization across multiple devices. It also allows the sender
 to send a message while the recipient is offline.
 It does NOT provide a server side message archive, so that a new device could
 fetch old chat history.
 Most implementations of OMEMO use the signal-protocol libraries provided by
 OpenWhisperSystems. Unlike Smack, those libraries are licensed under the GPLv3,
 which prevents a Apache licensed OMEMO implementation using those libraries (see
 [licensing situation](https://github.com/igniterealtime/Smack/wiki/OMEMO-libsignal-Licensing-Situation)).
 The module smack-omemo therefore contains no code related to signal-protocol.
 However, almost all functionality is encapsulated in that module. If you want
 to use OMEMO in a GPLv3 licensed client, you can use the smack-omemo-signal
 Smack module, which binds the signal-protocol library to smack-omemo.
 It is also possible, to port smack-omemo to other libraries implementing the
 double ratchet algorithm.
 Understanding the Double Ratchet Algorithm
 ------------------------------------------
 In the context of OMEMO encryption, a *recipient* is a not a user, but a users *device* (a user might have
 multiple devices of course).
 Unlike in PGP, each device capable of OMEMO has its own identity key and publishes its own key bundle.
 It is not advised to migrate OMEMO identities from one device to another, as it might damage the ratchet
 if not done properly (more on that later). Sharing one identity key between multiple devices is not the purpose of
 OMEMO. If a contact has three OMEMO capable devices, you will see three different OMEMO identities and their
 fingerprints.
 OMEMO utilizes multiple layers of encryption when encrypting a message.
 The body of the message is encrypted with a symmetric message key (AES-128-GCM) producing a *payload*.
 The message key is encrypted for each recipient using the double ratchet algorithm.
 For that purpose, the sending device creates a session with the recipient device (if there was no session already).
 Upon receiving a message, the recipient selects the encrypted key addressed to them and decrypts it with their
 counterpart of the OMEMO session. The decrypted key gets then used to decrypt the message.
 One important consequence of forward secrecy is, that whenever an OMEMO message gets decrypted,
 the state of the ratchet changes and the key used to decrypt the message gets deleted.
 There is no way to recover this key a second time. The result is, that every message can be decrypted
 exactly once.
 In order to provide the best user experience, it is therefore advised to implement a client side message archive,
 since solutions like MAM cannot be used to fetch old, already once decrypted OMEMO messages.
 Server-side Requirements
 ------------------------
 In order to use OMEMO encryption, your server and the servers of your chat
 partners must support PEP ([XEP-0163](http://xmpp.org/extensions/xep-0163.html)) 
 to store and exchange key bundles.
 Optionally your server should support Message Carbons ([XEP-0280](http://xmpp.org/extensions/xep-0280.html))
 and Message Archive Management ([XEP-0313](http://xmpp.org/extensions/xep-0313.html))
 to achieve message synchronization across all (on- and offline) devices.
 Client-side Requirements
 ------------------------
 If you are want to run smack-omemo related code on the Windows platform, you might have to install the
 [Java Cryptography Extension](http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html).
 This is needed to generate cryptographically strong keys.
 Storing Keys
 ------------
 smack-omemo needs to create, store and delete some information like keys and session states during operation.
 For that purpose the `OmemoStore` class is used. There are multiple implementations with different properties.
 * The `(Signal)FileBasedOmemoStore` stores all information in individual files organized in a directory tree.
 While this is the most basic and easy to use implementation, it is not the best solution in terms of performance.
 * The `(Signal)CachingOmemoStore` is a multi-purpose store implementation. It can be used to wrap another
 `(Signal)OmemoStore` implementation to provide a caching layer (for example in order to reduce access to a database backend or
 a the file system of the `FileBasedOmemoStore`. It is therefore advised to wrap persistent `(Signal)OmemoStore`
 implementations with a `(Signal)CachingOmemoStore`.
 On the other hand it can also be used standalone as an ephemeral `OmemoStore`, which "forgets" all stored information
 once the program terminates. This comes in handy for testing purposes.
 If you are unhappy with the `(Signal)FileBasedOmemoStore`, you can implement your own store (for example with a
 SQL database) by extending the `(Signal)OmemoStore` class.
 It most certainly makes sense to store the data of the used `OmemoStore` in a secure way (for example an
 encrypted database).
 Handling Trust Decisions
 ------------------------
 In order for a cryptographic system to make sense, decisions must be made whether to *trust* an identity or not.
 For technical reasons those decisions cannot be stored within the `OmemoStore`. Instead a client must implement
 the `OmemoTrustCallback`. This interface provides methods to mark `OmemoFingerprints` as trusted or untrusted and to
 query trust decisions.
 In order to provide security, a client should communicate to the user, that it is important for them to compare
 fingerprints through an external channel (reading it out on the phone, scanning QR codes...) before starting to chat.
 While not implemented in smack-omemo, it is certainly for the client to implement different trust models like
 [Blind Trust Before Verification](https://gultsch.de/trust.html).
 Basic Setup
 -----------
 Before you can start to send and receive messages, some preconditions have to be met. These steps should be executed
 in the order as presented below. In this example we will use components from the *smack-omemo-signal* module.
 1. Register an OmemoService
   The `OmemoService` class is responsible for handling incoming messages and manages access to the Double Ratchet.
   ```
   SignalOmemoService.setup();
   ```
   The `setup()` method registers the service as a singleton. You can later access the instance
   by calling `SignalOmemoService.getInstace()`. The service can only be registered once.
   Subsequent calls will throw an `IllegalStateException`.
 2. Set an OmemoStore
   Now you have to decide, what `OmemoStore` implementation you want to use to store and access
   keys and session states. In this example we'll use the `SignalFileBasedOmemoStore` wrapped in a
   `SignalCachingOmemoStore` for better performance.
   ```
   SignalOmemoService service = SignalOmemoService.getInstace();
   service.setOmemoStoreBackend(new SignalCachingOmemoStore(new SignalFileBasedOmemoStore(new File("/path/to/store"))));
   ```
   Just like the `OmemoService` instance, the `OmemoStore` instance can only be set once.
 3. Get an instance of the OmemoManager for your connection
   For the greater part of OMEMO related actions, you'll use the `OmemoManager`. The `OmemoManager` represents
   your OMEMO device. While it is possible to have multiple `OmemoManager`s per `XMPPConnection`, you really
   only need one.
   ```
   OmemoManager manager = OmemoManager.getInstanceFor(connection);
   ```
   If for whatever reason you decide to use multiple `OmemoManager`s at once,
   it is highly advised to get them like this:
   ```
   OmemoManager first = OmemoManager.getInstanceFor(connection, firstId);
   OmemoManager second = OmemoManager.getInstanceFor(connection, secondId);
   ```
 4. Set an OmemoTrustCallback
   As stated above, the `OmemoTrustCallback` is used to query trust decisions. Set the callback like this:
   ```
   manager.setTrustCallback(trustCallback);
   ```
   If you use multiple `OmemoManager`s each `OmemoManager` MUST have its own callback.
 5. Set listeners for OMEMO messages.
   To get notified of incoming OMEMO encrypted messages, you need to register corresponding listeners.
   There are two types of listeners.
   * `OmemoMessageListener` is used to listen for incoming encrypted OMEMO single chat messages and
   KeyTransportMessages.
   * `OmemoMucMessageListener` is used to listen for encrypted OMEMO messages sent in a MultiUserChat.
   Note that an incoming message might not have a body. That might be the case for
   [KeyTransportMessages](https://xmpp.org/extensions/xep-0384.html#usecases-keysend)
   or messages sent to update the ratchet. You can check, whether a received message is such a message by calling
   `OmemoMessage.Received.isKeyTransportMessage()`, which will return true if the message has no body.
   The received message will include the senders device and fingerprint, which you can use in
   `OmemoManager.isTrustedOmemoIdentity(device, fingerprint)` to determine, if the message was sent by a trusted device.
 6. Initialize the manager(s)
   Ideally all above steps should be executed *before* `connection.login()` gets called. That way you won't miss
   any offline messages. If the connection is not yet logged in, now is the time to do so.
   ```
   connection.login();
   manager.initialize();
   ```
   Since a lot of keys are generated in this step, this might take a little longer on older devices.
   You might want to use the asynchronous call `OmemoManager.initializeAsync(initializationFinishedCallback)`
   instead to prevent the thread from blocking.
 Send Messages
 -------------
 Encrypting a message for a contact really means to encrypt the message for all trusted devices of the contact, as well
 as all trusted devices of the user itself (except the sending device). The encryption process will fail if there are
 devices for which the user has not yet made a trust decision.
 ### Make Trust Decisions
 To get a list of all devices of a contact, you can do the following:
 ```
 List<OmemoDevice> devices = manager.getDevicesOf(contactsBareJid);
 ```
 To get the OmemoFingerprint of a device, you can call
 ```
 OmemoFingerprint fingerprint = manager.getFingerprint(device);
 ```
 This fingerprint can now be displayed to the user who can decide whether to trust the device, or not.
 ```
 // Trust
 manager.trustOmemoIdentity(device, fingerprint);
 // Distrust
 manager.distrustOmemoIdentity(device, fingerprint);
 ```
 ### Encrypt a Message
 Currently only Message bodies can be encrypted.
 ```
 String secret = "Mallory is a twerp!";
 OmemoMessage.Sent encrypted = manager.encrypt(contactsBareJid, secret);
 ```
 The encrypted message will contain some information about the message. It might for example happen, that the encryption
 failed for some recipient devices. For that reason the encrypted message will contain a map of skipped devices and
 the reasons.
 ### Encrypt a Message for a MultiUserChat
 A MultiUserChat must fulfill some criteria in order to be OMEMO capable.
 The MUC must be non-anonymous. Furthermore all members of the MUC must have subscribed to one another.
 You can check for the non-anonymity like follows:
 ```
 manager.multiUserChatSupportsOmemo(muc);
 ```
 Encryption is then done analog to single message encryption:
 ```
 OmemoMessage.Sent encrypted = manager.encrypt(multiUserChat, secret);
 ```
 ### Sending an encrypted Message
 To send the message, it has to be wrapped in a `Message` object. That can conveniently be done like follows.
 ```
 Message message = encrypted.asMessage(contactsJid);
 connection.sendStanza(message):
 ```
 This will add a [Message Processing Hint](https://xmpp.org/extensions/xep-0334.html) for MAM,
 an [Explicit Message Encryption](https://xmpp.org/extensions/xep-0380.html) hint for OMEMO,
 as well as an optional cleartext hint about OMEMO to the message.
 Configuration
 -------------
 smack-omemo has some configuration options that can be changed on runtime via the `OmemoConfiguration` class:
 * setIgnoreStaleDevices when set to true, smack-omemo will stop encrypting messages for **own** devices that have not send a message for some period of time (configurable in setIgnoreStaleDevicesAfterHours)
 * setDeleteStaleDevices when set to true, smack-omemo will remove own devices from the device list, if no messages were received from them for a period of time (configurable in setDeleteStaleDevicesAfterHours)
 * setRenewOldSignedPreKeys when set to true, smack-omemo will periodically generate and publish new signed prekeys. Via setRenewOldSignedPreKeysAfterHours you can configure, after what period of time new keys are generated and setMaxNumberOfStoredSignedPreKeys allows configuration of how many signed PreKeys are kept in storage for decryption of delayed messages.
 * setAddOmemoBodyHint when set to true, a plaintext body with a hint about OMEMO encryption will be added to the message. This hint will be displayed by clients that do not support OMEMO. Note that this might not be desirable when communicating with clients that do not support EME.
 * setRepairBrokenSessionsWithPreKeyMessages when set to true, whenever a message arrives, which cannot be decrypted, smack-omemo will respond with a preKeyMessage which discards the old session and builds a fresh one.
 * setCompleteSessionWithEmptyMessage when set to true, whenever a preKeyMessage arrives, smack-omemo will respond with an empty message to complete the session.
 Integration Tests
 -----------------
 smack-omemo comes with a set of integration tests. Lets say you want to run the integration test suite for smack-omemo-signal.
 You can do so by using the following gradle task:
 ```
 gradle omemoSignalIntTest

 Migrating smack-omemo from 4.2.1 to 4.x.x
 =========================================
 The implementation of smack-omemo and smack-omemo-signal was originally started as an
 academic project under pressure of time.
 For that reason, the API was not perfect when OMEMO support was first introduced in
 Smack in version 4.2.1.
 Many issues of smack-omemo have been resolved over the course of the last year in
 a major effort, which is why smack-omemo and smack-omemo-signalwere excluded from
 the 4.2.2 release.
 During this time major parts of the implementation were redone and the API changed
 as a consequence of that. This guide will go through all notable changes in order
 to make the process of upgrading as easy and straight forward as possible.
 ## Trust
 One major change is, that the OmemoStore implementations no longer store trust decisions.
 Methods related to trust have been removed from OmemoStore implementations.
 Instead the client is now responsible to store those.
 Upon startup, the client now must pass an `OmemoTrustCallback` to the `OmemoManager`
 which is used to access and change trust decisions.
 It is recommended for the client to store trust decisions as tuples of (omemo device,
 fingerprint of identityKey, trust state).
 When querying a trust decision (aka. "Is this fingerprint trusted for that device?),
 the local fingerprint should be compared to the provided fingerprint.
 The method signatures for setting and querying trust from inside the OmemoManager are
 still the same. Internally they access the `OmemoTrustCallback` set by the client.
 ## Encryption
 Message encryption in smack-omemo 4.2.1 was ugly. Encryption for multiple devices
 could fail because session negotiation could go wrong, which resulted in an
 exception, which contained all devices with working sessions.
 That exception could then be used in 
 `OmemoManager.encryptForExistingSessions(CannotEstablishOmemoSessionException exception, String message)`,
 to encrypt the message for all devices with a session.

 Privacy Lists
 ============
 [Back](index.md)
 [XEP-0016: Privacy Lists](http://xmpp.org/extensions/xep-0016.html)
 What is it?
 -----------
 `Privacy` is a method for users to block communications from particular other
 users. In XMPP this is done by managing one's privacy lists.
 Server-side privacy lists enable successful completion of the following use
 cases:
  * Retrieving one's privacy lists.
  * Adding, removing, and editing one's privacy lists.
  * Setting, changing, or declining active lists.
  * Setting, changing, or declining the default list (i.e., the list that is active by default).
  * Allowing or blocking messages based on JID, group, or subscription type (or globally).
  * Allowing or blocking inbound presence notifications based on JID, group, or subscription type (or globally).
  * Allowing or blocking outbound presence notifications based on JID, group, or subscription type (or globally).
  * Allowing or blocking IQ stanzas based on JID, group, or subscription type (or globally).
  * Allowing or blocking all communications based on JID, group, or subscription type (or globally).
 How can I use it?
 -----------------
 The API implementation releases three main public classes:
  * `PrivacyListManager`: this is the main API class to retrieve and handle server privacy lists.
  * `PrivacyList`: witch represents one privacy list, with a name, a set of privacy items. For example, the list with visible or invisible.
  * `PrivacyItem`: block or allow one aspect of privacy. For example, to allow my friend to see my presence.
 1. Right from the start, a client MAY **get his/her privacy list** that is stored in the server:
 ```
 // Create a privacy manager for the current connection._
 PrivacyListManager privacyManager = PrivacyListManager.getInstanceFor(myConnection);
 // Retrieve server privacy lists_
 PrivacyList[] lists = privacyManager.getPrivacyLists();
 ```
 Now the client is able to show every `PrivacyItem` of the server and also for
 every list if it is active, default or none of them. The client is a listener
 of privacy changes.
 2. In order to **add a new list in the server**, the client MAY implement something like:
 ```
 // Set the name of the list_
 String listName = "newList";
 // Create the list of PrivacyItem that will allow or deny some privacy aspect_
 String user = "tybalt@example.com";
 String groupName = "enemies";
 ArrayList privacyItems = new ArrayList();
 PrivacyItem item = new PrivacyItem(PrivacyItem.Type.jid, user, true, 1);
 privacyItems.add(item);
 item = new PrivacyItem(PrivacyItem.Type.subscription, PrivacyItem.SUBSCRIPTION_BOTH, true, 2);
 privacyItems.add(item);
 item = new PrivacyItem(PrivacyItem.Type.group, groupName, false, 3);
 item.setFilterMessage(true);
 privacyItems.add(item);
 // Get the privacy manager for the current connection._
 PrivacyListManager privacyManager = PrivacyListManager.getInstanceFor(myConnection);
 // Create the new list._
 privacyManager.createPrivacyList(listName, privacyItems);
 ```
 3. To **modify an existent list**, the client code MAY be like:
 ```
 // Set the name of the list_
 String listName = "existingList";
 // Get the privacy manager for the current connection._
 PrivacyListManager privacyManager = PrivacyListManager.getInstanceFor(myConnection);
 // Sent the new list to the server._
 privacyManager.updatePrivacyList(listName, items);
 ```
 Notice `items` was defined at the example 2 and MUST contain all the elements
 in the list (not the "delta").
 4. In order to **delete an existing list**, the client MAY perform something like:
 ```
 // Set the name of the list_
 String listName = "existingList";
 // Get the privacy manager for the current connection._
 PrivacyListManager privacyManager = PrivacyListManager.getInstanceFor(myConnection);
 // Remove the list._
 privacyManager.deletePrivacyList(listName);
 ```
 5. In order to **decline the use of an active list**, the client MAY perform something like:
 ```
 // Get the privacy manager for the current connection._
 PrivacyListManager privacyManager = PrivacyListManager.getInstanceFor(myConnection);
 // Decline the use of the active list._
 privacyManager.declineActiveList();
 ```
 6. In order to **decline the use of a default list**, the client MAY perform something like:
 ```
 // Get the privacy manager for the current connection._
 PrivacyListManager privacyManager = PrivacyListManager.getInstanceFor(myConnection);
 // Decline the use of the default list._
 privacyManager.declineDefaultList();
 ```
 Listening for Privacy Changes
 In order to handle privacy changes, clients SHOULD listen manager's updates.
 When a list is changed the manager notifies every added listener. Listeners
 MUST implement the `PrivacyListListener` interface. Clients may need to react
 when a privacy list is modified. The `PrivacyListManager` lets you add
 listerners that will be notified when a list has been changed. Listeners
 should implement the `PrivacyListListener` interface.
 The most important notification is `updatedPrivacyList` that is performed when
 a privacy list changes its privacy items.
 The listener becomes notified after performing:
 ```
 // Get the privacy manager for the current connection._
 PrivacyListManager privacyManager = PrivacyListManager.getInstanceFor(myConnection);
 // Add the listener (this) to get notified_
 privacyManager.addListener(this);
 ```

 Stanza Properties
 =================
 [Back](index.md)
 Smack provides an easy mechanism for attaching arbitrary properties to
 packets. Each property has a String name, and a value that is a Java primitive
 (int, long, float, double, boolean) or any Serializable object (a Java object
 is Serializable when it implements the Serializable interface).
 Using the API
 -------------
 All major objects have property support, such as Message objects. The
 following code demonstrates how to set properties:
 ```
 Message message = chat.createMessage();
 JivePropertiesExtension jpe = new JivePropertiesExtension();
 // Add a Color object as a property._
 jpe.setProperty("favoriteColor", new Color(0, 0, 255));
 // Add an int as a property._
 jpe.setProperty("favoriteNumber", 4);
 // Add the JivePropertiesExtension to the message packet_
 message.addStanzaExtension(jpe);
 chat.sendMessage(message);
 ```
 Getting those same properties would use the following code:
 ```
 Message message = chat.nextMessage();
 // Get the JivePropertiesExtension_
 JivePropertiesExtension jpe = message.getExtension(JivePropertiesExtension.NAMESPACE);
 // Get a Color object property._
 Color favoriteColor = (Color)jpe.getProperty("favoriteColor");
 // Get an int property. Note that properties are always returned as
 // Objects, so we must cast the value to an Integer, then convert
 // it to an int._
 int favoriteNumber = ((Integer)jpe.getProperty("favoriteNumber")).intValue();
 ```
 For convenience `JivePropertiesManager` contains two helper methods namely
 `addProperty(Stanza packet, String name, Object value)` and
 `getProperty(Stanza packet, String name)`.
 Objects as Properties
 ---------------------
 Using objects as property values is a very powerful and easy way to exchange
 data. However, you should keep the following in mind:
  * When you send a Java object as a property, only clients running Java will be able to interpret the data. So, consider using a series of primitive values to transfer data instead.
  * Objects sent as property values must implement Serialiable. Additionally, both the sender and receiver must have identical versions of the class, or a serialization exception will occur when de-serializing the object.
  * Serialized objects can potentially be quite large, which will use more bandwidth and server resources.
 XML Format
 ----------
 The current XML format used to send property data is not a standard, so will
 likely not be recognized by clients not using Smack. The XML looks like the
 following (comments added for clarity):
    <!-- All properties are in a x block. -->
    <properties xmlns="http://www.jivesoftware.com/xmlns/xmpp/properties">
        <!-- First, a property named "prop1" that's an integer. -->
        <property>
            <name>prop1</name>
            <value type="integer">123</value>
        <property>
        <!-- Next, a Java object that's been serialized and then converted
             from binary data to base-64 encoded text. -->
        <property>
            <name>blah2</name>
            <value type="java-object">adf612fna9nab</value>
        <property>
    </properties>
 The currently supported types are: `integer`, `long`, `float`, `double`,
 `boolean`, `string`, and `java-object`.

 Pubsub
 ======
 [Back](index.md)
 This section details the usage of an API designed for accessing an XMPP based
 implementation of a [publish and
 subscribe](http://en.wikipedia.org/wiki/Publish/subscribe) based messaging
 system. It has functionality for creation, configuration of, subscription and
 publishing to pubsub nodes.
  * Node creation and configuration
  * Publishing to a node
  * Receiving pubsub messages
  * Retrieving persisted pubsub messages
  * Discover pubsub information
 **XEP related:** [XEP-0060](http://xmpp.org/extensions/xep-0060.html)
 Node creation and configuration
 -------------------------------
 ### Description
 Allowed users may create and configure pubsub nodes. There are two types of
 nodes that can be created, leaf nodes and collection nodes.
 * Leaf Nodes - contains only messages
 * Collection Nodes - contains only nodes (both Leaf and Collection are allowed), but no messages
 The current version of this API only supports Leaf Nodes. There are many
 configuration options available for nodes, but the two main options are
 whether the node is **persistent** or not and whether it will deliver payload
 or not.
 ### Usage
 In order to create a node you will need to first create an instance of
 _**PubSubManager**_. There are several options for node creation which range
 from creating an instant node, default configuration, or a fully configured
 node.
 ### Examples
 Create an instant node:
 ```
 // Create a pubsub manager using an existing XMPPConnection
 PubSubManager mgr = new PubSubManager(con);
 // Create the node
 LeafNode leaf = mgr.createNode();
 ```
 Create a node with default configuration and then configure it:
 ```
 // Create a pubsub manager using an existing XMPPConnection
 PubSubManager mgr = PubSubManager.getInstanceFor(con);
 // Create the node
 LeafNode leaf = mgr.createNode("testNode");
 ConfigureForm form = new ConfigureForm(FormType.submit);
 form.setAccessModel(AccessModel.open);
 form.setDeliverPayloads(false);
 form.setNotifyRetract(true);
 form.setPersistentItems(true);
 form.setPublishModel(PublishModel.open);
 leaf.sendConfigurationForm(form);
 ```
 Create and configure a node:
 ```
 // Create a pubsub manager using an existing XMPPConnection
 PubSubManager mgr = PubSubManager.getInstanceFor(con);
 // Create the node
 ConfigureForm form = new ConfigureForm(FormType.submit);
 form.setAccessModel(AccessModel.open);
 form.setDeliverPayloads(false);
 form.setNotifyRetract(true);
 form.setPersistentItems(true);
 form.setPublishModel(PublishModel.open);
 LeafNode leaf = mgr.createNode("testNode", form);
 ```
 Publishing to a node
 --------------------
 **Description**
 This section deals with the **publish** portion of pubsub. Usage of a node
 typically involves either sending or receiving data, referred to as items.
 Depending on the context of the nodes usage, the item being sent to it can
 have different properties. It can contain application data known as payload,
 or the publisher may choose to supply meaningful unique id's. Determination of
 an items acceptable properties is defined by a combination of node
 configuration and its purpose.
 **Usage**
 To publish to a node, you will have to either create or retrieve an existing
 node and then create and send items to that node. The ability for any given
 person to publish to the node will be dependent on its configuration.
 **Examples**
 In this example we publish an item to a node that does not take payload:
 ```
 // Create a pubsub manager using an existing XMPPConnection
 PubSubManager mgr = PubSubManager.getInstanceFor(con);
 // Get the node
 LeafNode node = mgr.getNode("testNode");
 // Publish an Item, let service set the id
 node.send(new Item());
 // Publish an Item with the specified id
 node.send(new Item("123abc"));
 ```
 In this example we publish an item to a node that does take payload:
 ```
 // Create a pubsub manager using an existing XMPPConnection
 PubSubManager mgr = PubSubManager.getInstanceFor(con);
 // Get the node
 LeafNode node = mgr.getNode("testNode");
 // Publish an Item with payload
 node.send(new PayloadItem("test" + System.currentTimeMillis(),
 new SimplePayload("book", "pubsub:test:book", "Two Towers")));
 ```
 Receiving pubsub messages
 -------------------------
 **Description**
 This section deals with the **subscribe** portion of pubsub. As mentioned in
 the last section, usage of a node typically involves either sending or
 receiving items. Subscribers are interested in being notified when items are
 published to the pubsub node. These items may or may not have application
 specific data (payload), as that is dependent on the context in which the node
 is being used.
 **Usage**
 To get messages asynchronously when items are published to a node, you will
 have to
 * Get a node.
 * Create and register a listener.
 * Subscribe to the node.
 Please note that you should register the listener before subscribing so that
 all messages sent after subscribing are received. If done in the reverse
 order, messages that are sent after subscribing but before registering a
 listener may not be processed as expected.
 **Examples**
 In this example we can see how to create a listener and register it and then
 subscribe for messages.
 ```
 // Create a pubsub manager using an existing XMPPConnection
 PubSubManager mgr = PubSubManager.getInstanceFor(con);
 // Get the node
 LeafNode node = mgr.getNode("testNode");
 node.addItemEventListener(new ItemEventCoordinator&ltItem;>());
 node.subscribe(myJid);
 ```
 Where the listener is defined like so:
 ```
 class ItemEventCoordinator  implements ItemEventListener {
 	@Override
 	public void handlePublishedItems(ItemPublishEvent items) {
 		System.out.println("Item count: " + System.out.println(items);
 	}
 }
 ```
 In addition to receiving published items, there are notifications for several
 other events that occur on a node as well.
 * Deleting items or purging all items from a node
 * Changing the node configuration
 In this example we can see how to create a listener, register it and then
 subscribe for item deletion messages.
 ```
 // Create a pubsub manager using an existing XMPPConnection
 PubSubManager mgr = PubSubManager.getInstanceFor(con);
 // Get the node
 LeafNode node = mgr.getNode("testNode");
 node.addItemDeleteListener(new ItemDeleteCoordinator&ltItem;>());
 node.subscribe(myJid);
 node.deleteItem("id_one");
 ```
 Where the handler is defined like so:
 ```
 class ItemDeleteCoordinator implements ItemDeleteListener {
 	@Override
 	public void handleDeletedItems(ItemDeleteEvent items) {
 		System.out.println("Item count: " + items.getItemIds().size());
 		System.out.println(items);
 	}
 	@Override
 	public void handlePurge() {
 		System.out.println("All items have been deleted from node");
 	}
 }
 ```
 In this example we can see how to create a listener, register it and then
 subscribe for node configuration messages.
 ```
 // Create a pubsub manager using an existing XMPPConnection
 PubSubManager mgr = PubSubManager.getInstanceFor(con);
 // Get the node
 Node node = mgr.getNode("testNode");
 node.addConfigurationListener(new NodeConfigCoordinator());
 node.subscribe(myJid);
 ConfigureForm form = new ConfigureForm(FormType.submit);
 form.setAccessModel(AccessModel.open);
 form.setDeliverPayloads(false);
 form.setNotifyRetract(true);
 form.setPersistentItems(true);
 form.setPublishModel(PublishModel.open);
 node.sendConfigurationForm(form);
 ```
 Where the handler is defined like so:
 ```
 class NodeConfigCoordinator implements NodeConfigListener {
 	@Override
 	public void handleNodeConfiguration(ConfigurationEvent config) {
 		System.out.println("New configuration");
 		System.out.println(config.getConfiguration());
 	}
 }
 ```
 Retrieving persisted pubsub messages
 ------------------------------------
 **Description**
 When persistent nodes are used, the subscription and registration methods
 described in the last section will not enable the retrieval of items that
 already exist in the node. This section deals with the specific methods for
 retrieving these items. There are several means of retrieving existing items.
 You can retrieve all items at once, the last N items, or the items specified
 by a collection of id's. Please note that the service may, according to the
 pubsub specification, reply with a list of items that contains only the item
 id's (no payload) to save on bandwidth. This will not occur when the id's are
 specified since this is the means of guaranteeing retrieval of payload.
 **Usage**
 To synchronously retrieve existing items from a persistent node, you will have
 to get an instance of a _**LeafNode**_ and call one of the retrieve methods.
 **Examples**
 In this example we can see how to retrieve the existing items from a node:
 ```
 // Create a pubsub manager using an existing XMPPConnection
 PubSubManager mgr = PubSubManager.getInstanceFor(con);
 // Get the node
 LeafNode node = mgr.getNode("testNode");
 Collection<? extends Item> items = node.getItems();
 ```
 In this example we can see how to retrieve the last N existing items:
 ```
 // Create a pubsub manager using an existing XMPPConnection
 PubSubManager mgr = PubSubManager.getInstanceFor(con);
 // Get the node
 LeafNode node = mgr.getNode("testNode");
 List<? extends Item> items = node.getItems(100);
 ```
 In this example we can see how to retrieve the specified existing items:
 ```
 // Create a pubsub manager using an existing XMPPConnection
 PubSubManager mgr = PubSubManager.getInstanceFor(con);
 // Get the node
 LeafNode node = mgr.getNode("testNode");
 Collection&ltString;> ids = new ArrayList&ltString;>(3);
 ids.add("1");
 ids.add("3");
 ids.add("4");
 List<? extends Item> items = node.getItems(ids);
 ```
 Discover pubsub information
 ---------------------------
 **Description**
 A user may want to query a server or node for a variety of pubsub related
 information.
 **Usage**
 To retrieve information, a user will simply use either the _**PubSubManager**_
 or _**Node**_ classes depending on what type of information is required.
 **Examples**
 In this example we can see how to get pubsub capabilities:
 ```
 // Create a pubsub manager using an existing XMPPConnection
 PubSubManager mgr = PubSubManager.getInstanceFor(con);
 // Get the pubsub features that are supported
 DiscoverInfo supportedFeatures = mgr.getSupportedFeatures();
 ```
 In this example we can see how to get pubsub subscriptions for all nodes:
 ```
 // Create a pubsub manager using an existing XMPPConnection
 PubSubManager mgr = PubSubManager.getInstanceFor(con);
 // Get all the subscriptions in the pubsub service
 List&ltSubscription;> subscriptions = mgr.getSubscriptions();
 ```
 In this example we can see how to get all affiliations for the users bare JID
 on the pubsub service:
 ```
 // Create a pubsub manager using an existing XMPPConnection
 PubSubManager mgr = PubSubManager.getInstanceFor(con);
 // Get the affiliations for the users bare JID
 List&ltAffiliation;> affiliations = mgr.getAffiliations();
 ```
 In this example we can see how to get information about the node:
 ```
 // Create a pubsub manager using an existing XMPPConnection
 PubSubManager mgr = PubSubManager.getInstanceFor(con);
 Node node = mgr.getNode("testNode");
 // Get the node information
 DiscoverInfo nodeInfo = node.discoverInfo();
 ```
 In this example we can see how to discover the node items:
 ```
 // Create a pubsub manager using an existing XMPPConnection
 PubSubManager mgr = PubSubManager.getInstanceFor(con);
 Node node = mgr.getNode("testNode");
 // Discover the node items
 DiscoverItems nodeItems = node.discoverItems();
 ```
 In this example we can see how to get node subscriptions:
 ```
 // Create a pubsub manager using an existing XMPPConnection
 PubSubManager mgr = PubSubManager.getInstanceFor(con);
 Node node = mgr.getNode("testNode");
 // Discover the node subscriptions
 List&ltSubscription;> subscriptions = node.getSubscriptions();

 Roster Item Exchange
 ====================
 [Back](index.md)
 This extension is used to send rosters, roster groups and roster entries from
 one XMPP Entity to another. It also provides an easy way to hook up custom
 logic when entries are received from other XMPP clients.
 Follow these links to learn how to send and receive roster items:
  * Send a complete roster
  * Send a roster's group
  * Send a roster's entry
  * Receive roster entries
 **XEP related:** [XEP-93](http://www.xmpp.org/extensions/xep-0093.html)
 Send a entire roster
 -------------------
 **Description**
 Sometimes it is useful to send a whole roster to another user. Smack provides
 a very easy way to send a complete roster to another XMPP client.
 **Usage**
 Create an instance of _**RosterExchangeManager**_ and use the **#send(Roster,
 String)** message to send a roster to a given user. The first parameter is the
 roster to send and the second parameter is the id of the user that will
 receive the roster entries.
 **Example**
 In this example we can see how user1 sends his roster to user2.
 ```
 XMPPConnection conn1 = …
 // Create a new roster exchange manager on conn1
 RosterExchangeManager rosterExchangeManager = new RosterExchangeManager(conn1);
 // Send user1's roster to user2
 rosterExchangeManager.send(Roster.getInstanceFor(conn1), user2);
 ```
 Send a roster group
 -------------------
 **Description**
 It is also possible to send a roster group to another XMPP client. A roster
 group groups a set of roster entries under a name.
 **Usage**
 Create an instance of _**RosterExchangeManager**_ and use the
 **#send(RosterGroup, String)** message to send a roster group to a given user.
 The first parameter is the roster group to send and the second parameter is
 the id of the user that will receive the roster entries.
 **Example**
 In this example we can see how user1 sends his roster groups to user2.
 ```
 XMPPConnection conn1 = …
 // Create a new roster exchange manager on conn1
 RosterExchangeManager rosterExchangeManager = new RosterExchangeManager(conn1);
 // Send user1's RosterGroups to user2
 for (Iterator it = Roster.getInstanceFor(conn1).getGroups(); it.hasNext(); )
 rosterExchangeManager.send((RosterGroup)it.next(), user2);
 ```
 Send a roster entry
 -------------------
 **Description**
 Sometimes you may need to send a single roster entry to another XMPP client.
 Smack also lets you send items at this granularity level.
 **Usage**
 Create an instance of _**RosterExchangeManager**_ and use the
 **#send(RosterEntry, String)** message to send a roster entry to a given user.
 The first parameter is the roster entry to send and the second parameter is
 the id of the user that will receive the roster entries.
 **Example**
 In this example we can see how user1 sends a roster entry to user2.
 ```
 XMPPConnection conn1 = …
 // Create a new roster exchange manager on conn1
 RosterExchangeManager rosterExchangeManager = new RosterExchangeManager(conn1);
 // Send a roster entry (any) to user2
 rosterExchangeManager1.send((RosterEntry)Roster.getInstanceFor(conn1).getEntries().next(), user2);
 ```
 Receive roster entries
 ----------------------
 **Description**
 Since roster items are sent between XMPP clients, it is necessary to listen to
 possible roster entries receptions. Smack provides a mechanism that you can
 use to execute custom logic when roster entries are received.
 **Usage**
  1. Create a class that implements the _**RosterExchangeListener**_ interface.
  2. Implement the method **entriesReceived(String, Iterator)** that will be called when new entries are received with custom logic.
  3. Add the listener to the _RosterExchangeManager_ that works on the desired _XMPPConnection_.
 **Example**
 In this example we can see how user1 sends a roster entry to user2 and user2
 adds the received entries to his roster.
 ```
 // Connect to the server and log in the users
 XMPPConnection conn1 = …
 XMPPConnection conn2 = …
 final Roster user2_roster = Roster.getInstanceFor(conn2);
 // Create a RosterExchangeManager that will help user2 to listen and accept
 the entries received
 RosterExchangeManager rosterExchangeManager2 = new RosterExchangeManager(conn2);
 // Create a RosterExchangeListener that will iterate over the received roster entries
 RosterExchangeListener rosterExchangeListener = new RosterExchangeListener() {
 public void entriesReceived(String from, Iterator remoteRosterEntries) {
 while (remoteRosterEntries.hasNext()) {
 try {
 // Get the received entry
 RemoteRosterEntry remoteRosterEntry = (RemoteRosterEntry) remoteRosterEntries.next();
 // Display the remote entry on the console
 System.out.println(remoteRosterEntry);
 // Add the entry to the user2's roster
 user2_roster.createEntry(
 remoteRosterEntry.getUser(),
 remoteRosterEntry.getName(),
 remoteRosterEntry.getGroupArrayNames());
 }
 catch (XMPPException e) {
 e.printStackTrace();
 }
 }
 }
 };
 // Add the RosterExchangeListener to the RosterExchangeManager that user2 is using
 rosterExchangeManager2.addRosterListener(rosterExchangeListener);
 // Create a RosterExchangeManager that will help user1 to send his roster
 RosterExchangeManager rosterExchangeManager1 = new RosterExchangeManager(conn1);
 // Send user1's roster to user2
 rosterExchangeManager1.send(Roster.getInstanceFor(conn1), user2);

 Spoiler Messages
 ================
 [Back](index.md)
 Spoiler Messages can be used to indicate that the body of a message is a spoiler and should be displayed as such.
 ## Usage
 To get an instance of the SpoilerManager, call 
 ```
 SpoilerManager manager = SpoilerManager.getInstanceFor(connection);
 ```
 This will automatically add Spoilers to the list of supported features of your client.
 The manager can then be used to add SpoilerElements to messages like follows:
 ```
 Message message = new Message();
 // spoiler without hint
 SpoilerElement.addSpoiler(message);
 // spoiler with hint about content
 SpoilerElement.addSpoiler(message, "End of Love Story");
 // spoiler with localized hint
 SpoilerElement.addSpoiler(message, "de", "Der Kuchen ist eine Lüge");
 ```
 To get Spoilers from a message call

 XHTML Messages
 ==============
 [Back](index.md)
 Provides the ability to send and receive formatted messages using XHTML.
 Follow these links to learn how to compose, send, receive and discover support
 for XHTML messages:
  * Compose an XHTML Message
  * Send an XHTML Message
  * Receive an XHTML Message
  * Discover support for XHTML Messages
 **XEP related:** [XEP-71](http://www.xmpp.org/extensions/xep-0071.html)
 Compose an XHTML Message
 ------------------------
 **Description**
 The first step in order to send an XHTML message is to compose it. Smack
 provides a special class that helps to build valid XHTML messages hiding any
 low level complexity. For special situations, advanced users may decide not to
 use the helper class and generate the XHTML by themselves. Even for these
 situations Smack provides a well defined entry point in order to add the
 generated XHTML content to a given message.
 Note: not all clients are able to view XHTML formatted messages. Therefore,
 it's recommended that you include a normal body in that message that is either
 an unformatted version of the text or a note that XHTML support is required to
 view the message contents.
 **Usage**
 Create an instance of _**XHTMLText**_ specifying the style and language of the
 body. You can add several XHTML bodies to the message but each body should be
 for a different language. Once you have an XHTMLText you can start to append
 tags and text to it. In order to append tags there are several messages that
 you can use. For each XHTML defined tag there is a message that you can send.
 In order to add text you can send the message **#append(String
 textToAppend)**.
 After you have configured the XHTML text, the last step you have to do is to
 add the XHTML text to the message you want to send. If you decided to create
 the XHTML text by yourself, you will have to follow this last step too. In
 order to add the XHTML text to the message send the message **#addBody(Message
 message, String body)** to the _**XHTMLManager**_ class where _message_ is the
 message that will receive the XHTML body and _body_ is the string to add as an
 XHTML body to the message.**
 **Example**
 In this example we can see how to compose the following XHTML message:
 ```
 <body>
 	<p style='font-size:large'>Hey John, this is my new
 		<span style='color:green'>green</span>
 		<em>!!!!</em>
 	</p>
 </body>
 ```
 ```
 // Create a message to send
 Message msg = chat.createMessage();
 msg.setSubject("Any subject you want");
 msg.setBody("Hey John, this is my new green!!!!");
 // Create an XHTMLText to send with the message
 XHTMLText xhtmlText = new XHTMLText(null, null);
 xhtmlText.appendOpenParagraphTag("font-size:large");
 xhtmlText.append("Hey John, this is my new ");
 xhtmlText.appendOpenSpanTag("color:green");
 xhtmlText.append("green");
 xhtmlText.appendCloseSpanTag();
 xhtmlText.appendOpenEmTag();
 xhtmlText.append("!!!!");
 xhtmlText.appendCloseEmTag();
 xhtmlText.appendCloseParagraphTag();
 xhtmlText.appendCloseBodyTag();
 // Add the XHTML text to the message
 XHTMLManager.addBody(msg, xhtmlText);
 ```
 Send an XHTML Message
 ---------------------
 **Description**
 After you have composed an XHTML message you will want to send it. Once you
 have added the XHTML content to the message you want to send you are almost
 done. The last step is to send the message as you do with any other message.
 **Usage**
 An XHTML message is like any regular message, therefore to send the message
 you can follow the usual steps you do in order to send a message. For example,
 to send a message as part of a chat just use the message **#sendMessage(Message)** of
 _**Chat**_ or you can use the message **#sendStanza(Stanza)** of
 _**XMPPConnection**_.
 **Example**
 In this example we can see how to send a message with XHTML content as part of
 a chat.
 ```
 // Create a message to send
 Message msg = chat.createMessage();
 // Obtain the XHTML text to send from somewhere
 XHTMLText xhtmlBody = getXHTMLTextToSend();
 // Add the XHTML text to the message
 XHTMLManager.addBody(msg, xhtmlBody);
 // Send the message that contains the XHTML
 chat.sendMessage(msg);
 ```
 Receive an XHTML Message
 ------------------------
 **Description**
 It is also possible to obtain the XHTML content from a received message.
 Remember that the specification defines that a message may contain several
 XHTML bodies where each body should be for a different language.
 **Usage**
 To get the XHTML bodies of a given message just send the message
 **#getBodies(Message)** to the class _**XHTMLManager**_. The answer of this
 message will be an _**List**_ with the different XHTML bodies of the
 message or null if none.
 **Example**
 In this example we can see how to create a PacketListener that obtains the
 XHTML bodies of any received message.
 ```
 // Create a listener for the chat and display any XHTML content
 IncomingChatMessageListener listener = new IncomingChatMessageListener() {
 public void newIncomingMessage(EntityBareJid from, Message message, Chat chat) {
    // Obtain the XHTML bodies of the message
    List<CharSequence> bodies = XHTMLManager.getBodies(message);
    if (bodies == null) {
        return;
    // Display the bodies on the console
    for (CharSequence body : bodies) {
        System.out.println(body);
    }
 }
 };
 chatManager.addListener(listener);
 ```
 Discover support for XHTML Messages
 -----------------------------------
 **Description**
 Before you start to send XHTML messages to a user you should discover if the
 user supports XHTML messages. There are two ways to achieve the discovery,
 explicitly and implicitly. Explicit is when you first try to discover if the
 user supports XHTML before sending any XHTML message. Implicit is when you
 send XHTML messages without first discovering if the conversation partner's
 client supports XHTML and depenging on the answer (normal message or XHTML
 message) you find out if the user supports XHTML messages or not. This section
 explains how to explicitly discover for XHTML support.
 **Usage**
 In order to discover if a remote user supports XHTML messages send
 **#isServiceEnabled(XMPPConnection connection, String userID)** to the class
 _**XHTMLManager**_ where connection is the connection to use to perform the
 service discovery and userID is the user to check (A fully qualified xmpp ID,
 e.g. jdoe@example.com). This message will return true if the specified user
 handles XHTML messages.
 **Example**
 In this example we can see how to discover if a remote user supports XHTML
 Messages.
 ```
 Message msg = chat.createMessage();
 // Include a normal body in the message
 msg.setBody(getTextToSend());
 // Check if the other user supports XHTML messages
 if (XHTMLManager.isServiceEnabled(connection, chat.getParticipant())) {
 	// Obtain the XHTML text to send from somewhere
 	String xhtmlBody = getXHTMLTextToSend();
 	// Include an XHTML body in the message
 	qHTMLManager.addBody(msg, xhtmlBody);
 }
 // Send the message
 chat.sendMessage(msg);

 Smack: Getting Started
 ======================
 [Back](index.md)
 This document will introduce you to the Smack API and provide an overview of
 important classes and concepts.
 Smack Modules and Requirements
 -------------------------------
 Smack is meant to be easily embedded into any existing Java application. The
 library ships as several modules to provide more flexibility over which
 features applications require:
  * `smack-core` -- provides core XMPP functionality. All XMPP features that are part of the XMPP RFCs are included.
  * `smack-im` -- provides functionality defined in RFC 6121 (XMPP-IM), like the Roster.
  * `smack-tcp` -- support for XMPP over TCP. Includes XMPPTCPConnection class, which you usually want to use
  * `smack-extensions` -- support for many of the extensions (XEPs) defined by the XMPP Standards Foundation, including multi-user chat, file transfer, user search, etc. The extensions are documented in the [extensions manual](extensions/index.md).
  * `smack-experimental` -- support for experimental extensions (XEPs) defined by the XMPP Standards Foundation. The API and functionality of those extensions should be considered as unstable.
  * `smack-legacy` -- support for legacy extensions (XEPs) defined by the XMPP Standards Foundation.
  * `smack-bosh` -- support for BOSH (XEP-0124). This code should be considered as beta.
  * `smack-resolver-minidns` -- support for resolving DNS SRV records with the help of MiniDNS. Ideal for platforms that do not support the javax.naming API. Also supports [DNSSEC](dnssec.md).
  * `smack-resolver-dnsjava` -- support for resolving DNS SRV records with the help of dnsjava.
  * `smack-resolver-javax` -- support for resolving DNS SRV records with the javax namespace API.
  * `smack-debug` -- an enhanced GUI debugger for protocol traffic. It will automatically be used when found in the classpath and when [debugging](debugging.md) is enabled.

 Smack has an initialization process that involves 2 phases.
  * Initializing system properties - Initializing all the system properties accessible through the class **SmackConfiguration**. These properties are retrieved by the _getXXX_ methods on that class.
  * Initializing startup classes - Initializing any classes meant to be active at startup by instantiating the class, and then calling the _initialize_ method on that class if it extends **SmackInitializer**. If it does not extend this interface, then initialization will have to take place in a static block of code which is automatically executed when the class is loaded.
 Initialization is accomplished via a configuration file. By default, Smack
 will load the one embedded in the Smack jar at _org.jivesoftware.smack/smack-
 config.xml_. This particular configuration contains a list of initializer
 classes to load. All manager type classes that need to be initialized are
 contained in this list of initializers.
 Establishing a Connection
 -------------------------
 The `XMPPTCPConnection` class is used to create a connection to an XMPP
 server. Below are code examples for making a connection:
 ```
 // Create a connection and login to the example.org XMPP service.
 AbstractXMPPConnection conn1 = new XMPPTCPConnection("username", "password", "example.org");
 conn1.connect().login();
 ```
 Further connection parameters can be configured by using a configuration builder:
 ```
 // Create a connection to the jabber.org server on a specific port.
 XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()
  .setUsernameAndPassword("username", "password")
  .setXmppDomain("jabber.org")
  .setHost("earl.jabber.org")
  .setPort(8222)
  .build();
 AbstractXMPPConnection conn2 = new XMPPTCPConnection(config);
 conn2.connect().login();
 ```
 Note that maximum security will be used when connecting to the server by
 default (and when possible), including use of TLS encryption. The
 ConnectionConfiguration class provides advanced control over the connection
 created, such as the ability to disable or require encryption. See
 [XMPPConnection Management](connections.md) for full details.
 Once you've created a connection, you should login with the
 `XMPPConnection.login()` method. Once you've logged in, you can begin
 chatting with other users by creating new `Chat` or `MultiUserChat`
 objects.
 Working with the Roster
 ----------------------
 The roster lets you keep track of the availability (presence) of other users.
 Users can be organized into groups such as "Friends" and "Co-workers", and
 then you discover whether each user is online or offline.
 Retrieve the roster using the `Roster.getInstanceFor(XMPPConnection)` method. The roster
 class allows you to find all the roster entries, the groups they belong to,
 and the current presence status of each entry.
 Reading and Writing Stanzas
 Each message to the XMPP server from a client is called a packet and is sent
 as XML. The `org.jivesoftware.smack.packet` package contains classes that
 encapsulate the three different basic packet types allowed by XMPP (message,
 presence, and IQ). Classes such as `Chat` and `GroupChat` provide higher-level
 constructs that manage creating and sending packets automatically, but you can
 also create and send packets directly. Below is a code example for changing
 your presence to let people know you're unavailable and "out fishing":
 ```
 // Create a new presence. Pass in false to indicate we're unavailable._
 Presence presence = new Presence(Presence.Type.unavailable);
 presence.setStatus("Gone fishing");
 // Send the stanza (assume we have an XMPPConnection instance called "con").
 con.sendStanza(presence);
 ```
 Smack provides two ways to read incoming packets: `StanzaListener`, and
 `StanzaCollector`. Both use `StanzaFilter` instances to determine which
 stanzas should be processed. A stanza listener is used for event style
 programming, while a stanza collector has a result queue of packets that you
 can do polling and blocking operations on. So, a stanza listener is useful
 when you want to take some action whenever a stanza happens to come in, while
 a stanza collector is useful when you want to wait for a specific packet to
 arrive. Stanza collectors and listeners can be created using an Connection
 instance.

 display, and composition of messages. There are three stages in this extension:<ol>
    <li>Request for event notifications,
    <li>Receive the event notification requests and send event notifications, and
    <li>Receive the event notifications.</ol>

 <hr>
 <div class="subheader"><a name="reqevnot">Requesting Event Notifications</a></div><p>
 <b>Description</b><p>
 In order to receive event notifications for a given message you first have to specify 
 which events are you interested in. Each message that you send has to request its own event 
 notifications. Therefore, every message that you send as part of a chat should request its own event 
 notifications.</p>
 <b>Usage</b><p>
 The class <i>MessageEventManager</i> provides an easy way for requesting event notifications. All you have to do is specify
 the message that requires the event notifications and the events that you are interested in.
 <p>Use the static method <i><b>MessageEventManager.addNotificationsRequests(Message message, boolean offline, boolean 
 delivered, boolean displayed, boolean composing)</b></i> for requesting event notifications.
 </p>
 <b>Example</b><p>
 Below you can find an example that logs in a user to the server, creates a message, adds the requests
 for notifications and sends the message.
 <blockquote>
 <pre>      <font color="#3f7f5f">// Connect to the server and log in</font>
      conn1 = new XMPPConnection(host);
      conn1.login(server_user1, pass1);
      <font color="#3f7f5f">// Create a chat with user2</font>
      Chat chat1 = conn1.createChat(user2);
      <font color="#3f7f5f">// Create a message to send</font>
      Message msg = chat1.createMessage();
      msg.setSubject(<font color="#0000FF">"Any subject you want"</font>);
      msg.setBody(<font color="#0000FF">"An interesting body comes here..."</font>);
      <font color="#3f7f5f">// Add to the message all the notifications requests (offline, delivered, displayed,</font>
      <font color="#3f7f5f">// composing)</font>
      MessageEventManager.addNotificationsRequests(msg, <font COLOR="#7f0055"><b>true</b></font>, <font COLOR="#7f0055"><b>true</b></font>, <font COLOR="#7f0055"><b>true</b></font>, <font COLOR="#7f0055"><b>true</b></font>);
      <font color="#3f7f5f">// Send the message that contains the notifications request</font>
      chat1.sendMessage(msg);
 </pre>
 </blockquote>
 <hr>
 <div class="subheader"><a name="lstevnotreq">Reacting to Event Notification Requests</a></div><p>
 <b>Description</b><p>
 You can receive notification requests for the following events: delivered, displayed, composing and offline. You 
 <b>must</b> listen for these requests and react accordingly.</p>
 <b>Usage</b><p>
 The general idea is to create a new <i>DefaultMessageEventRequestListener</i> that will listen to the event notifications 
 requests and react with custom logic.  Then you will have to add the listener to the 
 <i>MessageEventManager</i> that works on 
 the desired <i>XMPPConnection</i>.
 <p>Note that <i>DefaultMessageEventRequestListener</i> is a default implementation of the 
 <i>MessageEventRequestListener</i> interface.
 The class <i>DefaultMessageEventRequestListener</i> automatically sends a delivered notification to the sender of the message 
 if the sender has requested to be notified when the message is delivered. If you decide to create a new class that
 implements the <i>MessageEventRequestListener</i> interface, please remember to send the delivered notification.</p>
 <ul>
  <li>To create a new <i>MessageEventManager</i> use the <i><b>MessageEventManager(XMPPConnection)</b></i> constructor. 
  </li>
  <li>To create an event notification requests listener create a subclass of <i><b>DefaultMessageEventRequestListener</b></i> or
  create a class that implements the <i><b>MessageEventRequestListener</b></i> interface.
  </li>
  <li>To add a listener to the messageEventManager use the MessageEventManager's message 
 <i><b>addMessageEventRequestListener(MessageEventRequestListener)</b></i>.</li>
 </ul></p>
 <b>Example</b><p>
 Below you can find an example that connects two users to the server. One user will create a message, add the requests
 for notifications and will send the message to the other user. The other user will add a 
 <i>DefaultMessageEventRequestListener</i> 
 to a <i>MessageEventManager</i> that will listen and react to the event notification requested by the other user.

 Messaging using Chats
 =====================
 [Back](index.md)
 Sending messages back and forth is at the core of instant messaging. Although
 individual messages can be sent and received as packets, it's generally easier
 to treat the string of messages as a chat using the
 `org.jivesoftware.smack.chat2.Chat` class.
 Chat
 ----
 A chat creates a new thread of messages (using a thread ID) between two users.
 The following code snippet demonstrates how to create a new Chat with a user
 and then send them a text message:
 ```
 // Assume we've created an XMPPConnection name "connection"._
 ChatManager chatManager = ChatManager.getInstanceFor(connection);
 chatManager.addIncomingListener(new IncomingChatMessageListener() {
  @Override
  void newIncomingMessage(EntityBareJid from, Message message, Chat chat) {
    System.out.println("New message from " + from + ": " + message.getBody());
  }
 });
 EntityBareJid jid = JidCreate.entityBareFrom("jsmith@jivesoftware.com");
 Chat chat = chatManager.chatWith(jid);
 chat.send("Howdy!");
 }
 ```
 The `Chat.send(String)` method is a convenience method that creates a
 Message object, sets the body using the String parameter, then sends the
 message. In the case that you wish to set additional values on a Message
 before sending it, use the
 `Chat.send(Message)` method, as in the following code snippet:
 ```
 Message newMessage = new Message();
 newMessage.setBody("Howdy!");
 // Additional modifications to the message Stanza.
 JivePropertiesManager.addProperty(newMessage, "favoriteColor", "red");
 chat.send(newMessage);
 ```
 You'll also notice in the example above that we specified an IncomingChatMessageListener.
 The listener is notified any time a new chat message arrives.
 The following code snippet uses the listener
 as a parrot-bot -- it echoes back everything the other user types.
 ```
 // Assume a IncomingChatMessageListener we've setup with a ChatManager
 public void newIncomingMessage(EntityBareJid from, Message message, Chat chat) {
    // Send back the same text the other user sent us.
    chat.send(message.getBody());
 }
 ```

 Smack Overview
 ==============
 [Back](index.md)
 Smack is a library for communicating with XMPP servers to perform real-time
 communications, including instant messaging and group chat.
 Smack Key Advantages
 --------------------
  * Extremely simple to use, yet powerful API. Sending a text message to a user can be accomplished in only a few lines of code: 
    ```java
    AbstractXMPPConnection connection = new XMPPTCPConnection("mtucker", "password", "jabber.org");
    connection.connect().login();
    Message message = connection.getStanzaFactory()
                      .buildMessageStanza()
                      .to("jsmith@jivesoftware.com")
                      .setBody("Howdy! How are you?")
                      .build();
    connection.sendStanza(message);
    ```
 * Doesn't force you to code at the XMPP protocol level, as other libraries do. Smack provides intelligent higher level constructs such as the `Chat` and `Roster` classes, which let you program more efficiently. 
  * Does not require that you're familiar with the XMPP XML format, or even that you're familiar with XML. 
  * Provides easy machine to machine communication. Smack lets you set any number of properties on each message, including properties that are Java objects. 
  * Open Source under the Apache License 2.0, which means you can incorporate Smack into your commercial or non-commercial applications. 
 About XMPP
 ----------
 XMPP (eXtensible Messaging and Presence Protocol) is an open protocol
 standardized by the IETF and supported and extended by the XMPP Standards
 Foundation (XSF, [http://www.xmpp.org](http://www.xmpp.org)).
 How To Use This Documentation
 -----------------------------
 This documentation assumes that you're already familiar with the main features
 of XMPP instant messaging. It's also highly recommended that you open the
 Javadoc API guide and use that as a reference while reading through this
 documentation.

 Processing Incoming Stanzas
 ===========================
 [Back](index.md)
 Smack provides a flexible framework for processing incoming stanzas using two
 constructs:
  * `org.jivesoftware.smack.StanzaCollector` -- a class that lets you synchronously wait for new stanzas.
  * `org.jivesoftware.smack.StanzaListener` -- an interface for asynchronously notifying you of incoming stanzas.  A stanza listener is used for event style programming, while a stanza collector has a result queue of stanzas that you can do polling and blocking operations on. So, a stanza listener is useful when you want to take some action whenever a stanza happens to come in, while a stanza collector is useful when you want to wait for a specific stanza to arrive. Stanza collectors and listeners can be created using an `XMPPConnection` instance.
 The `org.jivesoftware.smack.filter.StanzaFilter` interface determines which
 specific stanzas will be delivered to a `StanzaCollector` or `StanzaListener`.
 Many pre-defined filters can be found in the `org.jivesoftware.smack.filter`
 package.
 The following code snippet demonstrates registering both a stanza collector
 and a stanza listener:
 ```
 // Create a stanza filter to listen for new messages from a particular
 // user. We use an AndFilter to combine two other filters._
 StanzaFilter filter = new AndFilter(StanzaTypeFilter.MESSAGE, 
 	FromMatchesFilter.create(JidCreate.entityBareFrom("mary@jivesoftware.com")));
 // Assume we've created an XMPPConnection named "connection".
 // First, register a stanza collector using the filter we created.
 StanzaCollector myCollector = connection.createStanzaCollector(filter);
 // Normally, you'd do something with the collector, like wait for new packets.
 // Next, create a stanza listener. We use an anonymous inner class for brevity.
 StanzaListener myListener = new StanzaListener() {
 		public void processStanza(Stanza stanza) {
 			// Do something with the incoming stanza here._
 		}
 	};
 // Register the listener._
 connection.addAsyncStanzaListener(myListener, filter);
 // or for a synchronous stanza listener use
 connection.addSyncStanzaListener(myListener, filter);
 ```
 Standard Stanza Filters
 -----------------------
 A rich set of stanza filters are included with Smack, or you can create your
 own filters by coding to the `StanzaFilter` interface. The default set of
 filters includes:
  * `StanzaTypeFilter` -- filters for stanzas that are a particular Class type.
  * `StanzaIdFilter` -- filters for stanzas with a particular packet ID.
  * `ThreadFilter` -- filters for message stanzas with a particular thread ID.
  * `ToMatchesFilter` -- filters for stanzas that are sent to a particular address.
  * `FromMatchesFilter` -- filters for stanzas that are sent from a particular address.
  * `StanzaExtensionFilter` -- filters for stanzas that have a particular stanza extension.
  * `AndFilter` -- implements the logical AND operation over two filters.
  * `OrFilter` -- implements the logical OR operation over two filters.
  * `NotFilter` -- implements the logical NOT operation on a filter.

 Provider Architecture: Stanza Extensions and Custom IQ's
 ========================================================
 [Back](index.md)
 Introduction
 ------------
 The Smack provider architecture is a system for plugging in custom XML parsing
 of packet extensions and IQ packets. The standard [Smack
 Extensions](extensions/index.md) are built using the provider architecture.
 There are two types of providers:
  * `IQProvider` -- parses IQ requests into Java objects.
  * `Extension Provider` -- parses XML sub-documents attached to packets into ExtensionElement instances. By default, Smack only knows how to process a few standard packets and sub-packets that are in a few namespaces such as:
    * jabber:iq:auth
    * jabber:iq:roster
    * jabber:iq:register
 There are many more IQ types and extensions that are part of XMPP standards, and of course an endless number that can be added as custom extensions. To support this, an extensible parsing mechanism is provided via Smack and user build providers.
 Whenever a packet extension is found in a packet, parsing will be
 passed to the correct provider. Each provider must extend the
 ExtensionElementProvider abstract class. Each extension provider is
 responsible for parsing the raw XML stream, via the
 Smack's `XmlPullParser` interface, to construct an object.
 You can also create an introspection provider
 (`provider.IntrospectionProvider.PacketExtensionIntrospectionProvider`). Here,
 bean introspection is used to try to automatically set the properties
 of the class using the values in the packet extension sub-element.
 When no extension provider is registered for an element name and namespace
 combination, Smack will store all top-level elements of the sub-packet in the
 StandardExtensionElement object and then attach it to the packet.
 Management of these providers is accomplished via the [ProviderManager]()
 class. There are multiple ways to add providers to the manager.
  * Call addXXProvider methods - You can call the appropriate add methods directly.
 ```
 ProviderManager.addIQProvider("element", "namespace", new MyIQProvider());
 ProviderManager.addExtensionProvider("element", "namespace", new MyExtProvider());
 ```
  * Add a loader - You can add a ProviderLoader which will inject a means of loading multiple providers (both types) into the manager. This is the mechanism used by Smack to load from the Smack specific file format (via ProviderFileLoader). Implementers can provide the means to load providers from any source they wish, or simply reuse the ProviderFileLoader to load from their own provider files.
 ```
 	ProviderManager.addLoader(new ProviderFileLoader(FileUtils.getStreamForUrl("classpath:com/myco/provider/myco_custom.providers", null)));
 ```
  * VM Argument - You can add a provider file via the VM argument _smack.provider.file_. This will load the file at the specified URL during startup when Smack initializes. This also assumes the default configuration, since it requires that the **VmArgInitializer** was part of the startup configuration.
 `-Dsmack.provider.file=classpath:com/myco/provider/myco_custom.providers`
 or
 `-Dsmack.provider.file=file:///c:/myco/provider/myco_custom.providers`
 IQ Providers
 ------------
 The IQ provider class must extend the IQProvider abstract class. Each
 IQProvider is responsible for parsing the raw XML stream to create an
 IQ instance.
 You can also create an introspection provider
 (`provider.IntrospectionProvider.IQIntrospectionProvider`). Which
 uses bean introspection to try to automatically set properties of the
 IQ instance using the values found in the IQ packet XML. For example,
 an XMPP time packet resembles the following:
 ### Introspection
 _Time Stanza_
 	<iq type='result' to='joe@example.com' from='mary@example.com' id='time_1'>
 		<query xmlns='jabber:iq:time'>
 			<utc>20020910T17:58:35</utc>
 			<tz>MDT</tz>
 			<display>Tue Sep 10 12:58:35 2002</display>
 		</query>
 	</iq>
 _Time IQ Class_
 	class Time extends IQ {
 		private Date utc;
 		private TimeZone timeZone;
 		private String display;
 		@Override
 		public String getChildElementXML() {
 			return null;
 		}
 		public void setUtc(String utcString) {
 			try {
 				utc = StringUtils.parseDate(utcString);
 			} catch (ParseException e) {
 			}
 		}
 		public void setTimeZone(String zone) {
 			timeZone = TimeZone.getTimeZone(zone);
 		}
 		public void setDisplay(String timeDisplay) {
 			display = timeDisplay;
 		}
 	}
 _Time Provider_
 ```java
 public class TimeProvider extends IQIntrospectionProvider<Time> {
    public TimeProvider() {
        super(Time.class);
    }
 }
 ```
 The introspection service will automatically try to convert the String value
 from the XML into a boolean, int, long, float, double, or Class depending on
 the type the IQ instance expects.
 ### Custom IQProvider example
 Let's assume you want to write a provider for a new, unsupported IQ in Smack.
 _Custom IQ_
 ```
 <iq type='set' from='juliet@capulet.example/balcony' to='romeo@montage.example'>
  <myiq xmlns='example:iq:foo' token='secret'>
    <user age='42'>John Doe</user>
    <location>New York</location>
  </myiq>
 </iq>
 ```
 _Custom IQ Provider_
 ```java
 public class MyIQProvider extends IQProvider<MyIQ> {
  @Override
  public MyIQ parse(XmlPullParser parser, int initialDepth) throws XmlPullParserException, IOException {
    // Define the data we are trying to collect with sane defaults
    int age = -1;
    String user = null;
    String location = null;
    // Start parsing loop
    outerloop: while(true) {
      XmlPullParser.Event eventType = parser.next();
      switch(eventType) {
      case START_ELEMENT:
        String elementName = parser.getName();
        switch (elementName) {
        case "user":
          age = ParserUtils.getIntegerAttribute(parser, "age");
          user = parser.nextText();
          break;
        case "location"
          location = parser.nextText();
          break;
        }
        break;
      case END_ELEMENT:
        // Abort condition: if the are on a end tag (closing element) of the same depth
        if (parser.getDepth() == initialDepth) {
          break outerloop;
        }
        break;
      default:
        // Catch all for incomplete switch (MissingCasesInEnumSwitch) statement.
        break;
      }
    }
    // Construct the IQ instance at the end of parsing, when all data has been collected
    return new MyIQ(user, age, location);
  }
 }
 ```
 ### DiscoItemsProvider
 _Disco Items Stanza_
 	<iq type='result' from='shakespeare.lit' to='romeo@montague.net/orchard' id='items1'>
 	   <query xmlns='http://jabber.org/protocol/disco#items'>
 		   <item jid='people.shakespeare.lit' name='Directory of Characters'/>
 		   <item jid='plays.shakespeare.lit' name='Play-Specific Chatrooms'/>
 		   <item jid='mim.shakespeare.lit' name='Gateway to Marlowe IM'/>

 		   <item jid='en2fr.shakespeare.lit' name='French Translation Service'/>
 	   </query>
 	</iq>
 _Disco Items IQProvider_
 	public class DiscoverItemsProvider implements IQProvider<DiscoverItems> {
 		public DiscoverItems parseIQ(XmlPullParser parser, int initialDepth) throw XmlPullParserException, IOException {
 			DiscoverItems discoverItems = new DiscoverItems();
 			DiscoverItems.Item item;
 			String jid = "";
 			String name = "";
 			String action = "";
 			String node = "";
 			discoverItems.setNode(parser.getAttributeValue("", "node"));
 			outerloop: while (true) {
 				XmlPullParser.Event eventType = parser.next();
 				switch (eventType) {
 				case START_ELEMENT:
 					String elementName = parser.getName();
 					switch (elementName) {
 					case "item":
 						// Initialize the variables from the parsed XML
 						jid = parser.getAttributeValue("", "jid");
 						name = parser.getAttributeValue("", "name");
 						node = parser.getAttributeValue("", "node");
 						action = parser.getAttributeValue("", "action");
 						break;
 					}
 					break;
 				case END_ELEMENT:
 					String elementName = parser.getName();
 					switch (elementName) {
 					case "item":
 						// Create a new Item and add it to DiscoverItems.
 						item = new DiscoverItems.Item(jid);
 						item.setName(name);
 						item.setNode(node);
 						item.setAction(action);
 						discoverItems.addItem(item);
 						break;
 					case "query":
 					    if (parser.getDepth() == initialDepth) {
 							break outerloop;
 						}
 						break;
 					}
 				}
 			}
 			return discoverItems;
 		}
 	}
 Extension Providers
 -------------------
 Stanza extension providers are responsible for parsing packet extensions,
 which are child elements in a custom namespace of IQ, message and presence
 packets.
 _Pubsub Subscription Stanza_
 	<iq type='result' from='pubsub.shakespeare.lit' to='francisco@denmark.lit/barracks' id='sub1'>
 	   <pubsub xmlns='http://jabber.org/protocol/pubsub'>
 		   <subscription node='princely_musings' jid='francisco@denmark.lit' subscription='unconfigured'>
 			   <subscribe-options>
 				   <required/>
 			   </subscribe-options>
 		   </subscription>
 	   </pubsub>
 	</iq>
 _Subscription PacketExtensionProvider Implementation_
 	public class SubscriptionProvider extends ExtensionElementProvider<ExtensionElement> {
 		public ExtensionElement parse(XmlPullParser parser) throws Exception {
 			String jid = parser.getAttributeValue(null, "jid");
 			String nodeId = parser.getAttributeValue(null, "node");
 			String subId = parser.getAttributeValue(null, "subid");
 			String state = parser.getAttributeValue(null, "subscription");
 			boolean isRequired = false;
 			XmlPullParser.Event tag = parser.next();
 			if ((tag == XmlPullParser.START_ELEMENT) && parser.getName().equals("subscribe-options")) {
 				tag = parser.next();
 				if ((tag == XmlPullParser.START_ELEMENT) && parser.getName().equals("required"))
 					isRequired = true;
 				while (parser.next() != XmlPullParser.END_ELEMENT && parser.getName() != "subscribe-options");
 			}
 			while (parser.getEventType() != XmlPullParser.END_ELEMENT) parser.next();
 			return new Subscription(jid, nodeId, subId, state == null ? null : Subscription.State.valueOf(state), isRequired);
 		}
 	}
 Provider file format
 --------------------
 This is the format for a provider file which can be parsed by the
 **ProviderFileLoader**.
 	<?xml version="1.0"?>
 	<smackProviders>
 	<iqProvider>
 		<elementName>query</elementName>
 		<namespace>jabber:iq:time</namespace>
 		<className>org.jivesoftware.smack.packet.Time</className>
 	</iqProvider>
 	<iqProvider>
 		<elementName>query</elementName>
 		<namespace>http://jabber.org/protocol/disco#items</namespace>
 		<className>org.jivesoftware.smackx.provider.DiscoverItemsProvider</className>
 	</iqProvider>
 	<extensionProvider>
 		<elementName>subscription</elementName>
 		<namespace>http://jabber.org/protocol/pubsub</namespace>
 		<className>org.jivesoftware.smackx.pubsub.provider.SubscriptionProvider</className>
 	</extensionProvider>
 	</smackProviders>
 Each provider is associated with an element name and a namespace. If multiple
 provider entries attempt to register to handle the same namespace, the last
 entry added to the **ProviderManager** will overwrite any other that was
 loaded before it.

 Roster and Presence
 ===================
 [Back](index.md)
 The roster lets you keep track of the availability ("presence") of other
 users. A roster also allows you to organize users into groups such as
 "Friends" and "Co-workers". Other IM systems refer to the roster as the buddy
 list, contact list, etc.
 A `Roster` instance is obtained using the `Roster.getInstanceFor(XMPPConnection)` method.
 A detailed descriptrion of the protcol behind the Roster and Presence
 semantics can be found in [RFC
 6120](https://tools.ietf.org/html/rfc6121).
 Roster Entries
 --------------
 Every user in a roster is represented by a RosterEntry, which consists of:
  * An XMPP address, aka. JID (e.g. jsmith@example.com).
  * A name you've assigned to the user (e.g. "Joe").
  * The list of groups in the roster that the entry belongs to. If the roster entry belongs to no groups, it's called an "unfiled entry".  The following code snippet prints all entries in the roster: 
 ```
 Roster roster = Roster.getInstanceFor(connection);
 Collection<RosterEntry> entries = roster.getEntries();
 for (RosterEntry entry : entries) {
 	System.out.println(entry);
 }
 ```
 Methods also exist to get individual entries, the list of unfiled entries, or
 to get one or all roster groups.
 Presence
 ![Roster](images/roster.png)
 Every entry in the roster has presence associated with it. The
 `Roster.getPresence(BareJid user)` method will return a Presence object with
 the user's presence or `null` if the user is not online or you are not
 subscribed to the user's presence. _Note:_ Presence subscription is
 nnot tied to the user being on the roster, and vice versa: You could
 be subscriped to a remote users presence without the user in your roster, and
 a remote user can be in your roster without any presence subscription relation.
 A user either has a presence of online or offline. When a user is online,
 their presence may contain extended information such as what they are
 currently doing, whether they wish to be disturbed, etc. See the Presence
 class for further details.
 Listening for Roster and Presence Changes
 -----------------------------------------
 The typical use of the roster class is to display a tree view of groups and
 entries along with the current presence value of each entry. As an example,
 see the image showing a Roster in the Exodus XMPP client to the right.
 The presence information will likely change often, and it's also possible for
 the roster entries to change or be deleted. To listen for changing roster and
 presence data, a RosterListener should be used. To be informed about all
 changes to the roster the RosterListener should be registered before logging
 into the XMPP server. The following code snippet registers a RosterListener
 with the Roster that prints any presence changes in the roster to standard
 out. A normal client would use similar code to update the roster UI with the
 changing information.
 ```
 Roster roster = Roster.getInstanceFor(con);
 roster.addRosterListener(new RosterListener() {
 	// Ignored events public void entriesAdded(Collection<String> addresses) {}
 	public void entriesDeleted(Collection<String> addresses) {}
 	public void entriesUpdated(Collection<String> addresses) {}
 	public void presenceChanged(Presence presence) {
 		System.out.println("Presence changed: " + presence.getFrom() + " " + presence);
 	}
 });
 ```
 Note that in order to receive presence changed events you need to be subscribed
 to the users presence. See the following section.
 Adding Entries to the Roster
 ----------------------------
 Rosters and presence use a permissions-based model where users must give
 permission before someone else can see their presence. This protects a
 user's privacy by making sure that only approved users are able to view their
 presence information. Therefore, when you add a new roster entry, you will not
 see the presence information until the other user accepts your request.
 If another user requests a presence subscription, you must accept or reject
 that request. Smack handles presence subscription requests in one of three ways:
  * Automatically accept all presence subscription requests.
  * Automatically reject all presence subscription requests.
  * Process presence subscription requests manually.  The mode can be set using the `Roster.setSubscriptionMode(Roster.SubscriptionMode)` method. Simple clients normally use one of the automated subscription modes, while full-featured clients should manually process subscription requests and let the end-user accept or reject each request. If using the manual mode, a PacketListener should be registered that listens for Presence packets that have a type of `Presence.Type.subscribe`.

  <h2>Smack Modules</h2>
  <p>Smack is meant to be easily embedded into any existing Java
 	application. The library ships as several modules to provide more
 	flexibility over which features applications require.</p>
  <ul>
  <li>smack-core -- provides core XMPP functionality. All XMPP features that are part of the XMPP RFCs are included.</li>
  <li>smack-im -- provides functionality defined in RFC 6121 (XMPP-IM), like the Roster.</li>
  <li>{@link org.jivesoftware.smack.tcp smack-tcp} -- support for XMPP over TCP. Includes XMPPTCPConnection class, which you usually want to use</li>
  <li>smack-extensions -- support for many of the extensions (XEPs) defined by the XMPP Standards Foundation, including multi-user chat, file transfer, user search, etc. The extensions are documented in the [extensions manual](extensions/index.md).</li>
  <li>smack-experimental -- support for experimental extensions (XEPs) defined by the XMPP Standards Foundation. The API and functionality of those extensions should be considered as unstable.</li>
  <li>smack-legacy -- support for legacy extensions (XEPs) defined by the XMPP Standards Foundation.
  <li>smack-bosh -- support for BOSH (XEP-0124). This code should be considered as beta.</li>
  <li>smack-resolver-minidns -- support for resolving DNS SRV records with the help of <a href="https://minidns.org">MiniDNS</a>. Ideal for platforms that do not support the javax.naming API. Also supports [DNSSEC](dnssec.md) TODO: Fix link.</li>
  <li>smack-resolver-dnsjava -- support for resolving DNS SRV records with the help of dnsjava.</li>
  <li>smack-resolver-javax -- support for resolving DNS SRV records with the javax namespace API.</li>
  <li>smack-debug -- an enhanced GUI debugger for protocol traffic. It will automatically be used when found in the classpath and when [debugging](debugging.md) is enabled.</li>

    <!-- <li>{@link org.jivesoftware.smack.chat2.Chat}</li> -->
    <!-- More form index.md -->
  </ul>
  <h2>Smack Extensions</h2>
  <p>
 	Since the X in XMPP stands for eXstensible, Smack comes with many
 	built-in extensions for XMPP. Click
  </p>
  <blockquote><b>{@link org.jivesoftware.smackx}</b></blockquote>
  <p>
 	for an overview of all supporteted XMPP extensions of Smack.
  </p>
  Some selected extensions are
  <ul>
    <li>{@link org.jivesoftware.smackx.muc.MultiUserChat Multi-User Chat (XEP-0045)}</li>
    <li>{@link org.jivesoftware.smackx.carbons.CarbonManager Message Carbons (XEP-0289)}</li>
    <li>{@link org.jivesoftware.smackx.omemo OMEMO (XEP-0384)}</li>
    <!-- <li>{@link org.jivesoftware.smack.chat2.Chat}</li> -->
    <!-- More form index.md -->
  </ul>
  <h2>Configuration</h2>
  <p>Smack has an initialization process that involves 2 phases.</p>
  <ul>
 	<li>Initializing system properties - Initializing all the system properties accessible through the class **SmackConfiguration**. These properties are retrieved by the _getXXX_ methods on that class.</li>
 	<li>Initializing startup classes - Initializing any classes meant to be active at startup by instantiating the class, and then calling the _initialize_ method on that class if it extends **SmackInitializer**. If it does not extend this interface, then initialization will have to take place in a static block of code which is automatically executed when the class is loaded.</li>
  </ul>
  <p>
 	Initialization is accomplished via a configuration file.
 	By default, Smack
 will load the one embedded in the Smack jar at _org.jivesoftware.smack/smack-
 	config.xml_.
 	This particular configuration contains a list of initializer
 	classes to load.
 	All manager type classes that need to be initialized are
 	contained in this list of initializers.

 /**
 * The superclass of Smack's Modular Connection Architecture.
 * <p>
 * <b>Note:</b> Everything related to the modular connection architecture is currently considered experimental and
 * should not be used in production. Use the mature {@code XMPPTCPConnection} if you do not feel adventurous.
 * </p>
 * <p>
 * Smack's modular connection architecture allows to extend a XMPP c2s (client-to-server) connection with additional
 * functionality by adding modules. Those modules extend the Finite State Machine (FSM) within the connection with new
 * states. Connection modules can either be
 * <ul>
 * <li>Transports</li>
 * <li>Extensions</li>
 * </ul>
 * <p>
 * Transports bind the XMPP XML stream to an underlying transport like TCP, WebSockets, BOSH, and allow for the
 * different particularities of transports like DirectTLS
 * (<a href="https://xmpp.org/extensions/xep-0368.html">XEP-0368</a>). This eventually means that a single transport
 * module can implement multiple transport mechanisms. For example the TCP transport module implements the RFC6120 TCP
 * and the XEP-0368 direct TLS TCP transport bindings.
 * </p>
 * <p>
 * Extensions allow for a richer functionality of the connection. Those include
 * <ul>
 * <li>Compression</li>
 *   <li><ul>
 *   <li>zlib ([XEP-0138](https://xmpp.org/extensions/xep-0138.html))</li>
 *   <li>[Efficient XML Interchange (EXI)](https://www.w3.org/TR/exi/)</li>
 *   </ul></li>
 * <li>Instant Stream Resumption ([XEP-0397](https://xmpp.org/extensions/xep-0397.html)</li>
 * <li>Bind2</li>
 * <li>Stream Management</li>
 * </ul>
 * Note that not all extensions work with every transport. For example compression only works with TCP-based transport
 * bindings.
 * <p>
 * Connection modules are plugged into the the modular connection via their constructor. and they usually declare
 * backwards edges to some common, generic connection state of the FSM.
 * </p>
 * <p>
 * Modules and states always have an accompanying *descriptor* type. `ModuleDescriptor` and `StateDescriptor` exist
 * without an connection instance. They describe the module and state metadata, while their modules and states are
 * Instantiated once a modular connection is instantiated.
 * </p>

 /**
- * Provides pluggable parsing of incoming IQ's and extensions elements.
+ * The Smack provider architecture is a system for plugging in custom XML parsing of staza extensions
 * ({@link org.jivesoftware.smack.packet.ExtensionElement}, {@link org.jivesoftware.smack.packet.IQ} stanzas and
 * {@link org.jivesoftware.smack.packet.Nonza}. Hence, there are the the following providers:
 * <ul>
 * <li>{@link ExtensionElementProvider}</li>
 * <li>{@link IqProvider}</li>
 * <li>{@link NonzaProvider}</li>
 * </ul>
 * For most users, only extension element and IQ providers should be relevant.
 * <h2>Architecture</h2>
 * <p>
 * Providers are registered with the {@link ProviderManager}. XML elements identified by their
 * {@link javax.xml.namespace.QName}, that is, their qualified name consistent of the XML elements name and its
 * namespace. The QName is hence used to map XML elements to their provider Whenever a stanza extension is found in a
 * stanza, parsing will be passed to the correct provider. Each provider is responsible for parsing the XML stream via
 * Smack's {@link org.jivesoftware.smack.xml.XmlPullParser}.
 * </p>
 * <h2>Unknown Extension Elements</h2>
 * <p>
 * If no extension element provider is registered for an element, then Smack will fall back to parse the "unknown"
 * element to a {@link org.jivesoftware.smack.packet.StandardExtensionElement}.
 * </p>
 * <h2>Custom Provider Example</h2>
 * See {@link IqProvider} for examples.

 /**
- * Utilities for DNS related tasks.
+ * Smack's API for DNS related tasks.
 * <h2>DNSSEC and DANE</h2>
 * <h3>About</h3>
 * <p>
 * DNSSEC (<a href="https://tools.ietf.org/html/rfc4033">RFC 4033</a>, and others) authenticates DNS answers, positive
 * and negative ones. This means that if a DNS response secured by DNSSEC turns out to be authentic, then you can be
 * sure that the domain either exists, and that the returned resource records (RRs) are the ones the domain owner
 * authorized, or that the domain does not exists and that nobody tried to fake its non existence.
 * </p>
 * <p>
 * The tricky part is that an application using DNSSEC can not determine whether a domain uses DNSSEC, does not use
 * DNSSEC or if someone downgraded your DNS query using DNSSEC to a response without DNSSEC.
 * </p>
 * <p>
 * DANE (<a href="https://tools.ietf.org/html/rfc6698">RFC 6698</a>) allows the verification of a TLS certificate with
 * information stored in the DNS system and secured by DNSSEC. Thus DANE requires DNSSEC.
 * </p>
 * <h3>Prerequisites</h3>
 * <p>
 * From the three DNS resolver providers (MiniDNS, javax, dnsjava) supported by Smack we currently only support DNSSEc
 * with <a href="https://github.com/minidns/minidns">MiniDNS</a>. MiniDNS is the default resolver when smack-android is
 * used. For other configurations, make sure to add smack-resolver-minidns to your dependencies and call
 * `MiniDnsResolver.setup()` prior using Smack (e.g. in a `static {}` code block).
 * </p>
 * <h3>DNSSEC API</h3>
 * <p>
 * Smack's DNSSEC API is very simple. Just use
 * {@link org.jivesoftware.smack.ConnectionConfiguration.Builder#setDnssecMode(org.jivesoftware.smack.ConnectionConfiguration.DnssecMode)}
 * to enable DNSSEC. The argument, {@link org.jivesoftware.smack.ConnectionConfiguration.DnssecMode}, can be one of
 * <ul>
 * <li>{@link org.jivesoftware.smack.ConnectionConfiguration.DnssecMode#disabled}</li>
 * <li>{@link org.jivesoftware.smack.ConnectionConfiguration.DnssecMode#needsDnssec}</li>
 * <li>{@link org.jivesoftware.smack.ConnectionConfiguration.DnssecMode#needsDnssecAndDane}</li>
 * </ul>
 * The default is disabled.
 * <p>
 * If {@link org.jivesoftware.smack.ConnectionConfiguration.DnssecMode#needsDnssec} is used, then then Smack will only
 * connect if the DNS results required to determine a host for the XMPP domain could be verified using DNSSEC.
 * </p>
 * <p>
 * If set to {@link org.jivesoftware.smack.ConnectionConfiguration.DnssecMode#needsDnssecAndDane}, then then DANE will
 * be used to verify the XMPP service's TLS certificate if STARTTLS is used.
 * </p>
 * <h2>Best Practices</h2>
 * <p>
 * We recommend that applications using Smack's DNSSEC API do not ask the user if DNSSEC is avaialble. Instead they
 * should check for DNSSEC suport on every connection attempt. Once DNSSEC support has been discovered, the application
 * should use the `needsDnssec` mode for all future connection attempts. The same scheme can be applied when using DANE.
 * This approach is similar to the scheme established by to <a href="https://tools.ietf.org/html/rfc6797">HTTP Strict
 * Transport Security" (HSTS, RFC 6797</a>.
 * </p>

 /**
 * Smack's API for XEP-0332: HTTP over XMPP transport.
 * <h2 id="discover-hoxt-support">Discover HOXT support</h2>
 * <p>
 * <strong>Description</strong>
 * </p>
 * <p>
 * Before using this extension you must ensure that your counterpart supports it also.
 * </p>
 * <p>
 * <strong>Usage</strong>
 * </p>
 * <p>
 * Once you have your <em><strong>ServiceDiscoveryManager</strong></em> you will be able to discover information
 * associated with an XMPP entity. To discover the information of a given XMPP entity send
 * <strong>discoverInfo(entityID)</strong> to your <em><strong>ServiceDiscoveryManager</strong></em> where entityID is
 * the ID of the entity. The message <strong>discoverInfo(entityID)</strong> will answer with an instance of
 * <em><strong>DiscoverInfo</strong></em> that contains the discovered information.
 * </p>
 * <p>
 * <strong>Examples</strong>
 * </p>
 * <p>
 * In this example we can see how to check if the counterpart supports HOXT:
 * </p>
 *
 * <pre>
 * <code>// Obtain the ServiceDiscoveryManager associated with my XMPPConnection
 * ServiceDiscoveryManager discoManager = ServiceDiscoveryManager.getInstanceFor(connection);
 * // Get the information of a given XMPP entity, where entityID is a Jid
 * DiscoverInfo discoInfo = discoManager.discoverInfo(entityID);
 * // Check if room is HOXT is supported
 * boolean isSupported = discoInfo.containsFeature(&quot;urn:xmpp:http&quot;);</code>
 * </pre>
 *
 * <h2 id="iq-exchange">IQ exchange</h2>
 * <p>
 * <strong>Description</strong>
 * </p>
 * <p>
 * You can use IQ’s to perform HTTP requests and responses. This is applicable to relatively short requests and
 * responses (due to the limitation of XMPP message size).
 * </p>
 * <p>
 * <strong>Usage</strong>
 * </p>
 * <p>
 * First you need to register a <em><strong>StanzaListener</strong></em> to be able to handle intended IQs.
 * </p>
 * <p>
 * For the HTTP client you:
 * </p>
 * <ul>
 * <li>You create and send <em><strong>HttpOverXmppReq</strong></em> request.</li>
 * <li>Then you handle the <em><strong>HttpOverXmppResp</strong></em> response in your
 * <em><strong>StanzaListener</strong></em>.</li>
 * </ul>
 * <p>
 * For the HTTP server you:
 * </p>
 * <ul>
 * <li>You handle the <em><strong>HttpOverXmppReq</strong></em> requests in your
 * <em><strong>StanzaListener</strong></em>.</li>
 * <li>And create and send <em><strong>HttpOverXmppResp</strong></em> responses.</li>
 * </ul>
 * <p>
 * <strong>Examples</strong>
 * </p>
 * <p>
 * In this example we are an HTTP client, so we send a request (POST) and handle the response:
 * </p>
 *
 * <pre>
 * <code>
 * // create a request body
 * String urlEncodedMessage = &quot;I_love_you&quot;;
 *
 * // prepare headers
 * List&lt;Header&gt; headers = new ArrayList&lt;&gt;();
 * headers.add(new Header(&quot;Host&quot;, &quot;juliet.capulet.com&quot;));
 * headers.add(new Header(&quot;Content-Type&quot;, &quot;application/x-www-form-urlencoded&quot;));
 * headers.add(new Header(&quot;Content-Length&quot;, Integer.toString(urlEncodedMessage.length())));
 *
 * // provide body or request (not mandatory, - empty body is used for GET)
 * AbstractHttpOverXmpp.Text child = new AbstractHttpOverXmpp.Text(urlEncodedMessage);
 * AbstractHttpOverXmpp.Data data = new AbstractHttpOverXmpp.Data(child);
 *
 * // create request
 * HttpOverXmppReq req = HttpOverXmppReq.buider()
 *                             .setMethod(HttpMethod.POST)
 *                             .setResource(&quot;/mailbox&quot;)
 *                             .setHeaders(headers)
 *                             .setVersion(&quot;1.1&quot;)
 *                             .setData(data)
 *                             .build();
 *
 * // add to, where jid is the Jid of the individual the packet is sent to
 * req.setTo(jid);
 *
 * // send it
 * connection.sendIqWithResponseCallback(req, new StanzaListener() {
 *    public void processStanza(Stanza iq) {
 *         HttpOverXmppResp resp = (HttpOverXmppResp) iq;
 *         // check HTTP response code
 *         if (resp.getStatusCode() == 200) {
 *             // get content of the response
 *             NamedElement child = resp.getData().getChild();
 *             // check which type of content of the response arrived
 *             if (child instanceof AbstractHttpOverXmpp.Xml) {
 *                 // print the message and anxiously read if from the console ;)
 *                 System.out.println(((AbstractHttpOverXmpp.Xml) child).getText());
 *             } else {
 *                 // process other AbstractHttpOverXmpp data child subtypes
 *             }
 *         }
 *     }
 * });

 /**
- * Smack's API for XMPP IoT.
+ * Smack's API for XMPP IoT (XEP-0323, -0324, -0325, -0347).
 * <p>
 * The Internet of Things (IoT) XEPs are an experimental open standard how XMPP
 * can be used for IoT. They currently consists of
 * </p>
 * <ul>
 * <li>XEP-0323 Sensor Data</li>
 * <li>XEP-0324 Provisioning</li>
 * <li>XEP-0325 Control</li>
 * <li>XEP-0326 Concentrators</li>
 * <li>XEP-0347 Discovery</li>
 * </ul>
 * <p>
 * Smack only supports a subset of the functionality described by the XEPs!
 * </p>
 * <h2>Thing Builder</h2>
 * <p>
 * The {@link org.jivesoftware.smackx.iot.Thing} class acts as basic entity
 * representing a single "Thing" which can be used to retrieve data from or to
 * send control commands to. `Things` are constructed using a builder API.
 * </p>
 * <h2>Reading data from things</h2>
 * <p>
 * For example, we can build a Thing which provides the current temperature with
 * </p>
 *
 * <pre><code>
 * Thing dataThing = Thing.builder().setKey(key).setSerialNumber(sn).setMomentaryReadOutRequestHandler(new ThingMomentaryReadOutRequest() {
 *     {@literal @}Override
 *     public void momentaryReadOutRequest(ThingMomentaryReadOutResult callback) {
 *         int temp = getCurrentTemperature();
 *         IoTDataField.IntField field = new IntField("temperature", temp);
 *         callback.momentaryReadOut(Collections.singletonList(field));
 *     }
 * }).build();
 * </code></pre>
 * <p>
 * While not strictly required, most things are identified via a key and serial
 * number. We also build the thing with a "momentary read out request handler"
 * which when triggered, retrieves the current temperature and reports it back
 * to the requestor.
 * </p>
 * <p>
 * After the `Thing` is built, it needs to be made available so that other
 * entities within the federated XMPP network can use it. Right now we only
 * install the Thing in the `IoTDataManager`, which means the thing will act on
 * read out requests but not be managed by a provisioning server.
 * </p>
 *
 * <pre>
 * <code>
 * IoTDataManager iotDataManager = IoTDataManager.getInstanceFor(connection);
 * iotDataManager.installThing(thing);
 * </code>
 * </pre>
 * <p>
 * The data can be read out also by using the <code>IoTDataManager</code>:
 * </p>
 *
 * <pre>{@code
 * FullJid jid = …
 * List<IoTFieldsExtension> values = iotDataManager.requestMomentaryValuesReadOut(jid);
 * }</pre>
 * <p>
 * Now you have to unwrap the `IoTDataField` instances from the
 * `IoTFieldsExtension`. Note that Smack currently only supports a subset of the
 * specified data types.
 * </p>
 * <h2>Controlling a thing</h2>
 * <p>
 * Things can also be controlled, e.g. to turn on a light. Let's create a thing
 * which can be used to turn the light on and off.
 * </p>
 *
 * <pre>
 * <code>
 * Thing controlThing = Thing.builder().setKey(key).setSerialNumber(sn).setControlRequestHandler(new ThingControlRequest() {
 *     {@literal @}Override
 *     public void processRequest(Jid from, Collection&lt;SetData&gt;} setData) throws XMPPErrorException {
 *         for (final SetData data : setData) {
 *             if (!data.getName().equals("light")) continue;
 *             if (!(data instanceof SetBoolData)) continue;
 *             SetBoolData boolData = (SetBoolData) data;
 *             setLight(boolData.getBooleanValue());
 *         }
 *     }
 * }).build();
 * </code>
 * </pre>
 * <p>
 * Now we have to install this thing into the `IoTControlManager`:
 * </p>
 *
 * <pre>
 * <code>
 * IoTControlManager iotControlManager = IoTControlManager.getInstanceFor(connection);
 * iotControlManager.installThing(thing);
 * </code>
 * </pre>
 * <p>
 * The `IoTControlManager` can also be used to control a thing:
 * </p>
 *
 * <pre>
 * <code>
 * FullJid jid = …
 * SetData setData = new SetBoolData("light", true);
 * iotControlManager.setUsingIq(jid, setData);
 * </code>
 * </pre>
 * <p>
 * Smack currently only supports a subset of the possible data types for set
 * data.
 * </p>
 * <h2>Discovery</h2>
 * <p>
 * You may have wondered how a full JIDs of things can be determined. One
 * approach is using the discovery mechanisms specified in XEP-0347. Smack
 * provides the `IoTDiscoveryManager` as an API for this.
 * </p>
 * <p>
 * For example, instead of just installing the previous things in the
 * `IoTDataManager` and/or `IoTControlManager`, we could also use the
 * `IoTDiscoveryManger` to register the thing with a registry. Doing this also
 * installs the thing in the `IoTDataManager` and the `IoTControlManager`.
 * </p>
 *
 * <pre>
 * <code>
 * IoTDiscoveryManager iotDiscoveryManager = IoTDiscoveryManager.getInstanceFor(connection);
 * iotDiscovyerManager.registerThing(thing);
 * </code>
 * </pre>
 * <p>
 * The registry will now make the thing known to a broader audience, and
 * available for a potential owner.
 * </p>
 * <p>
 * The `IoTDiscoveryManager` can also be used to claim, disown, remove and
 * unregister a thing.
 * </p>
 * <h2>Provisioning</h2>
 * <p>
 * Things can usually only be used by other things if they are friends. Since a
 * thing normally can't decide on its own if an incoming friendship request
 * should be granted or not, we can delegate this decision to a provisioning
 * service. Smack provides the `IoTProvisinoManager` to deal with friendship and
 * provisioning.
 * </p>
 * <p>
 * For example, if you want to befriend another thing:
 * </p>
 *
 * <pre>
 * <code>
 * BareJid jid = …
 * IoTProvisioningManager iotProvisioningManager = IoTProvisioningManager.getInstanceFor(connection);
 * iotProvisioningManager.sendFriendshipRequest(jid);
 * </code>
 * </pre>
 *
 *

Martin Fidczuk	ffd027cc7d	Use XMPP connection as local SOCKS5 address The default local address is often just "the first address found in the list of addresses read from the OS" and this might mean an internal IP address that cannot reach external servers. So wherever possible use the same IP address being used to connect to the XMPP server because this local address has a better chance of being suitable. This MR adds the above behaviour, and two UTs to test that we use the local XMPP connection IP when connected, and the previous behaviour when not.	2023-04-26 10:00:23 +01:00

Furthermore, we only issue sendClose() if the WebSocket's output is still open, i.e., if there is a chance that it actually works.
