/**
|
|
* A group chat invitation packet extension, which is used to invite other
|
|
* users to a group chat room. To invite a 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:
|
|
*
|
|
* <pre>
|
|
* Message message = new Message("user@chat.example.com");
|
|
* message.setBody("Join me for a group chat!");
|
|
* message.addExtension(new GroupChatInvitation("room@chat.example.com"););
|
|
* con.sendPacket(message);
|
|
* </pre>
|
|
*
|
|
* To listen for group chat invitations, use a PacketExtensionFilter for the
|
|
* <tt>x</tt> element name and <tt>jabber:x:conference</tt> namespace, as in the
|
|
* following code example:
|
|
*
|
|
* <pre>
|
|
* PacketFilter filter = new PacketExtensionFilter("x", "jabber:x:conference");
|
|
* // Create a packet collector or packet listeners using the filter...
|
|
* </pre>
|
|
*
|
|
* <b>Note</b>: this protocol is outdated now that the Multi-User Chat (MUC) JEP is available
|
|
* (<a href="http://www.jabber.org/jeps/jep-0045.html">JEP-45</a>). However, most
|
|
* existing clients still use this older protocol. Once MUC support becomes more
|
|
* widespread, this API may be deprecated.
