Examples of PacketExtension

org.jivesoftware.smack.packet.PacketExtension
Interface to represent packet extensions. A packet extension is an XML subdocument with a root element name and namespace. Packet extensions are used to provide extended functionality beyond what is in the base XMPP specification. Examples of packet extensions include message events, message properties, and extra presence data. IQ packets cannot contain packet extensions. @see DefaultPacketExtension @see org.jivesoftware.smack.provider.PacketExtensionProvider @author Matt Tucker
org.xmpp.packet.PacketExtension
A packet extension represents a child element of a Packet for a given qualified name. The PacketExtension acts as a wrapper on a child element the same way Packet does for a whole element. The wrapper provides an easy way to handle the packet extension.
Subclasses of this class can be registered using the static variable registeredExtensions. The registration process associates the new subclass with a given qualified name (ie. element name and namespace). This information will be used by {@link Packet#getExtension(String,String)} for locating the corresponding PacketExtensionsubclass to return for the requested qualified name. Each PacketExtension must have a public constructor that takes an Element instance as an argument. @author Gaston Dombiak
