gloox: MUCRoom Class Reference

 class MyClass : public MUCRoomHandler
 {
   ...
 };

Then create a new MUCRoom object and pass it a valid ClientBase, the desired full room JID, your MUCRoomHandler-derived object, and an optional MUCRoomConfigHandler-derived object.

 void MyOtherClass::joinRoom( const std::string& room, const std::string& service,
                              const std::string& nick )
 {
   MyClass *myHandler = new MyClass(...);
   JID roomJID( room + "@" + service + "/" + nick );
   m_room = new MUCRoom( m_clientbase, roomJID, myHandler, 0 );
   m_room->join();
 }

When joining the room was successful, the various MUCRoomHandler functions will start to be called. If joining was not successful, MUCRoomHandler::handleMUCError() will be called, giving a hint at the reason for the failure.

To set up your own room, or to configure an existing room, you should also derive a class from MUCRoomConfigHandler and register it with the MUCRoom (either by using it with MUCRoom's constructor, or by calling registerMUCRoomConfigHandler()).

To quickly create an instant room to turn a one-to-one chat into a multi-user chat, see UniqueMUCRoom.

To send a private message to a room participant, use gloox::MessageSession with the participant's full room JID (room@service/nick).

Member Enumeration Documentation

enum HistoryRequestType

Allowable history request types. To disable sending of history, use any value except HistoryUnknown and specify a zero-length time span (using setRequestHistory()).

Enumeration values:

HistoryUnknown	It is up to the service to decide how much history to send. This is the default.
HistoryMaxChars	Limit the total number of characters in the history to "X" (where the character count is the characters of the complete XML stanzas, not only their XML character data).
HistoryMaxStanzas	Limit the total number of messages in the history to "X".
HistorySeconds	Send only the messages received in the last "X" seconds.
HistorySince	Send only the messages received since the datetime specified (which MUST conform to the DateTime profile specified in Jabber Date and Time Profiles (XEP-0082)).

Constructor & Destructor Documentation

MUCRoom	(	ClientBase *	parent,
		const JID &	nick,
		MUCRoomHandler *	mrh,
		MUCRoomConfigHandler *	mrch = `0`
	)

Creates a new abstraction of a Multi-User Chat room. The room is not joined automatically. Use join() to join the room, use leave() to leave it.

Parameters:

	parent	The ClientBase object to use for the communication.
	nick	The room's name and service plus the desired nickname in the form room@service/nick.
	mrh	The MUCRoomHandler that will listen to room events. May be 0 and may be specified later using registerMUCRoomHandler(). However, without one, MUC is no joy.
	mrch	The MUCRoomConfigHandler that will listen to room config result. Defaults to 0 initially. However, at the latest you need one when you create a new room which is not an instant room. You can set a MUCRoomConfigHandler using registerMUCRoomConfigHandler().

Member Function Documentation

void acknowledgeInstantRoom

(

)

Use this function to accept the room's default configuration. This function is useful only after MUCRoomHandler::handleMUCRoomCreation() was called. This is a NOOP at any other time.

Definition at line 652 of file mucroom.cpp.

void addHistory	(	const std::string &	message,
		const JID &	from,
		const std::string &	stamp
	)

Use this function to add history to a (newly created) room. The use case from the MUC spec is to add history to a room that was created in the process of a transformation of a one-to-one chat to a multi-user chat.

Parameters:

	message	A reason for declining the invitation.
	from	The JID of the original author of this part of the history.
	stamp	The datetime of the original message in the format: 20061224T12:15:23Z

Note:: You should not attempt to use this function before MUCRoomHandler::handleMUCParticipantPresence() was called for the first time.

Definition at line 248 of file mucroom.cpp.

MUCRoomAffiliation affiliation ( ) const [inline]

Returns the user's current affiliation with this room.

Returns:: The user's current affiliation.

Definition at line 180 of file mucroom.h.

void ban	(	const std::string &	nick,
		const std::string &	reason
	)

Use this function to ban a user from the room. Depending on service and/or room configuration and role/affiliation this may not always succeed. Usually, an affiliation of admin is necessary.

Note:: This is a convenience function. It directly uses setAffiliation() with a MUCRoomAffiliation of RoleOutcast.

Parameters:

	nick	The nick of the user to be banned.
	reason	An optional reason for the ban.

Definition at line 326 of file mucroom.cpp.

void cancelRoomCreation

Use this function to create a Tag that approves a voice request or registration request delivered via MUCRoomConfigHandler::handleMUCVoiceRequest(). You will need to send this Tag off manually using Client/ClientBase.

Parameters:

	room	The room's JID. This is needed because you can use this function outside of room context (e.g, if the admin is not in the room).
	df	The filled-in DataForm from the voice/registration request.

Definition at line 279 of file mucroom.cpp.

Stanza * declineInvitation	(	const JID &	room,

		const std::string &	password = `""`
	)

Use this function to destroy the room. All the occupants will be removed from the room.

Parameters:

	reason	An optional reason for the destruction.
	alternate	A pointer to a JID of an alternate venue (e.g., another MUC room). May be 0.

items

The list of items. Example:
You want to set the Voice List. The privilege of Voice refers to the role of Participant. Furthermore, you only store the delta of the original (Voice)List. (Optionally, you could probably store the whole list, however, remeber to include those items that were modified, too.) You want to, say, add one occupant to the Voice List, and remove another one. Therefore you store:

GuyOne, role participant -- this guy gets voice granted, he/she is now a participant.
GuyTwo, role visitor -- this guy gets voice revoked, he/she is now a mere visitor (Visitor is the Role "below" Participant in the privileges hierarchy).

For operations modifying Roles, you should specifiy only the new Role in the MUCListItem structure, for those modifying Affiliations, you should only specify the new Affiliation, respectively. The nickname is mandatory in the MUCListItem structure. Items without nickname will be ignored.

You may specify a reason for the role/affiliation change in the MUCListItem structure. You should not specify a JID in the MUCListItem structure, it will be ignored.

Parameters:

operation

See requestList() for a list of available list types. Any other value will be ignored.
