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.
