Class MultiUserChatManager

java.lang.Object

org.jivesoftware.smack.Manager

org.jivesoftware.smackx.muc.MultiUserChatManager

public final class MultiUserChatManager
extends Manager

A manager for Multi-User Chat rooms.

Use getMultiUserChat(EntityBareJid) to retrieve an object representing a Multi-User Chat room.

Automatic rejoin: The manager supports automatic rejoin of MultiUserChat rooms once the connection got re-established. This mechanism is disabled by default. To enable it, use setAutoJoinOnReconnect(boolean). You can set a AutoJoinFailedCallback via setAutoJoinFailedCallback(AutoJoinFailedCallback) to get notified if this mechanism failed for some reason. Note that as soon as rejoining for a single room failed, no further attempts will be made for the other rooms.

Note: For inviting other users to a group chat or listening for such invitations, take a look at the DirectMucInvitationManager which provides an implementation of XEP-0249: Direct MUC Invitations.

Method Details

getInstanceFor

public static MultiUserChatManager getInstanceFor(XMPPConnection connection)

Get a instance of a multi user chat manager for the given connection.

Parameters:

connection - TODO javadoc me please

Returns:

a multi user chat manager.

getMultiUserChat

public MultiUserChat getMultiUserChat(EntityBareJid jid)

Creates a multi user chat. Note: no information is sent to or received from the server until you attempt to join the chat room. On some server implementations, the room will not be created until the first person joins it.

Most XMPP servers use a sub-domain for the chat service (e.g.chat.example.com for the XMPP server example.com). You must ensure that the room address you're trying to connect to includes the proper chat sub-domain.

Parameters:

jid - the name of the room in the form "roomName@service", where "service" is the hostname at which the multi-user chat service is running. Make sure to provide a valid JID.

Returns:

MultiUserChat instance of the room with the given jid.
