ExtensionElement is now a marker interface that requires all
implementation non-abstract classes to carry a static final QNAME
field (of type QName). This is verified by a new unit test.
Also FullyQualifiedElement is renamed to simply XmlElement. XmlElement
is used over ExtensionElement when implementing classes do not
statically know the qualified name of the XML elements they
represent. In general, XmlElement should be used sparingly, and every
XML element should be modeled by its own Java class (implementing
ExtensionElement).
Returning a generic would allow for
List<ExtensionElement> list = stanza.getExtension("foo", "bar");
to compile (Note the we are calling getExtension(), not
getExtension*s*()).
Users are encouraged to use the type safe getExtension(Class<? extends
ExtensionElement) variant instead.
Fixes SMACK-825.
Introducing Smack's own XmlPullParser interface which tries to stay as
compatible as possible to XPP3. The interface is used to either wrap
StAX's XMLStreamReader if Smack is used on Java SE, and XPP3's
XmlPullParser if Smack is used on on Android.
Fixes SMACK-591.
Also introduce JUnit 5 and non-strict javadoc projects.
Type 'groupchat' message stanzas are not like others, they usually
require special handling. Hence such a filter is usually an indication
that multiple concepts are intermixed.
* Created filters to be used with incoming and outgoing message stanzas
* Added a list of ChatMarkersListener and its add and remove methods.
* Added a stanza listener for outgoing messages.
* Added a stanza listener for incoming messages.
* Added discover feature for XEP-0333.
* Added methods to inform a message was: received, displayed or ack
* Added javadoc autor tag.
