Detailed Description

This class implements Jabber/XMPP roster handling in the jabber:iq:roster namespace.

It takes care of changing presence, subscriptions, etc. You can modify any number of RosterItems within the Roster at any time. These changes must be synchronized with the server by calling synchronize(). Note that incoming Roster pushes initiated by other resources may overwrite changed values. Additionally, XEP-0083 (Nested Roster Groups) is implemented herein.

Constructor & Destructor Documentation

RosterManager ( ClientBase * parent )

Creates a new RosterManager.

Parameters

parent The ClientBase which is used for communication.

Definition at line 25 of file rostermanager.cpp.

~RosterManager ( )

virtual

Virtual destructor.

Definition at line 41 of file rostermanager.cpp.

Member Function Documentation

void ackSubscriptionRequest	(	const JID &	to,
		bool	ack
	)

Use this function to acknowledge a subscription request if you requested asynchronous subscription request handling.

Parameters

to	The JID to authorize/decline.
ack	Whether to authorize or decline the contact's request.

Definition at line 305 of file rostermanager.cpp.

void add	(	const JID &	jid,
		const std::string &	name,
		const StringList &	groups
	)

Use this function to add a contact to the roster. No subscription request is sent.

Note: Use unsubscribe() to remove an item from the roster.

Parameters

jid	The JID to add.
name	The displayed name of the contact.
groups	A list of groups the contact belongs to.

Definition at line 207 of file rostermanager.cpp.

void cancel	(	const JID &	jid,
		const std::string &	msg = `""`
	)

Use this function to cancel the contact's subscription to your presence. The contact will no longer receive presence from you.

Parameters

jid	The contact's JID.
msg	A message to send along with the request.

Since: 0.9

Note: Use remove() to remove a contact from the roster and to cancel its subscriptions.

Definition at line 246 of file rostermanager.cpp.

const std::string& delimiter ( ) const

inline

Use this function to retrieve the delimiter of Nested Roster Groups (XEP-0083).

Returns: The group delimiter.

Since: 0.7

Definition at line 140 of file rostermanager.h.

void fill ( )

This function does the initial filling of the roster with the current server-side roster.

Definition at line 64 of file rostermanager.cpp.

RosterItem * getRosterItem ( const JID & jid )

Lets you retrieve the RosterItem that belongs to the given JID.

Parameters

jid	The JID to return the RosterItem for.

Definition at line 480 of file rostermanager.cpp.

bool handleIq ( Stanza * stanza )

virtual

Reimplement this function if you want to be notified about incoming IQs.

Parameters

stanza The complete Stanza.

Returns: Indicates whether a request of type 'get' or 'set' has been handled. This includes the obligatory 'result' answer. If you return false, a 'error' will be sent.

Implements IqHandler.

Definition at line 85 of file rostermanager.cpp.

bool handleIqID	(	Stanza *	stanza,
		int	context
	)

virtual

Reimplement this function if you want to be notified about incoming IQs with a specific value of the id attribute. You have to enable tracking of those IDs using Client::trackID(). This is usually useful for IDs that generate a positive reply, i.e. <iq type='result' id='reg'/> where a namespace filter wouldn't work.

Parameters

stanza	The complete Stanza.
context	A value to restore context, stored with ClientBase::trackID().

Returns: Indicates whether a request of type 'get' or 'set' has been handled. This includes the obligatory 'result' answer. If you return false, a 'error' will be sent.

Implements IqHandler.

Definition at line 118 of file rostermanager.cpp.

void handlePresence ( Stanza * stanza )

virtual

Reimplement this function if you want to be updated on incoming presence notifications.

Parameters

stanza The complete stanza.

Implements PresenceHandler.

Definition at line 123 of file rostermanager.cpp.

void handlePrivateXML	(	const std::string &	tag,
		Tag *	xml
	)

virtual

Reimplement this function to receive the private XML that was requested earlier using PrivateXML::requestXML().

Parameters

tag	The tag of the storage packet.
xml	The private xml, i.e. the first child of the <query> tag.

Implements PrivateXMLHandler.

Definition at line 471 of file rostermanager.cpp.

void handlePrivateXMLResult	(	const std::string &	uid,
		PrivateXMLResult	pxResult
	)

virtual

This function is called to notify about the result of a 'store' or 'request' operation (successful requests are announced by means of handlePrivateXML()).

Parameters

uid	The ID of the query.
pxResult	The result of the operation.

Since: 0.7

Implements PrivateXMLHandler.

Definition at line 476 of file rostermanager.cpp.

void handleSubscription ( Stanza * stanza )

virtual

Reimplement this function if you want to be notified about incoming subscriptions/subscription requests.

Parameters

stanza The complete Stanza.

Implements SubscriptionHandler.

Definition at line 317 of file rostermanager.cpp.

void registerRosterListener	(	RosterListener *	rl,
		bool	syncSubscribeReq = `true`
	)

Register rl as object that receives updates on roster operations. For GUI applications it may be necessary to display a dialog or whatever to the user without blocking. If you want that, use asynchronous subscription requests. If you want to answer a request right away, make it synchronous.

Parameters

rl	The object that receives roster updates.
syncSubscribeReq	Indicates whether (Un)SubscriptionRequests shall be handled synchronous (true) or asynchronous (false). Default: synchronous.

Definition at line 373 of file rostermanager.cpp.

void remove ( const JID & jid )

Use this function to remove a contact from the roster. Subscription is implicitely cancelled.

Parameters

jid	The contact's JID.

Since: 0.9

Definition at line 258 of file rostermanager.cpp.

void removeRosterListener ( )

Complementary function to registerRosterListener. Removes the current RosterListener. Roster events will not be delivered anywhere.

Definition at line 379 of file rostermanager.cpp.

Roster * roster ( )

This function returns the roster.

Returns: Returns a map of JIDs with their current presence.

Definition at line 59 of file rostermanager.cpp.

void setDelimiter ( const std::string & delimiter )

Use this function to set the group delimiter (XEP-0083).

Parameters

delimiter The group delimiter.

Since: 0.7

Definition at line 463 of file rostermanager.cpp.

void subscribe	(	const JID &	jid,
		const std::string &	name = `""`,
		const StringList &	groups = `StringList()`,
		const std::string &	msg = `""`
	)

Use this function to subscribe to a new JID. The contact is added to the roster automatically (by compliant servers, as required by RFC 3921).

Parameters

jid	The address to subscribe to.
name	The displayed name of the contact.
groups	A list of groups the contact belongs to.
msg	A message sent along with the request.

Definition at line 188 of file rostermanager.cpp.

void synchronize ( )

Synchronizes locally modified RosterItems back to the server.

Definition at line 274 of file rostermanager.cpp.

void unsubscribe	(	const JID &	jid,
		const std::string &	msg = `""`
	)

Use this function to unsubscribe from a contact's presence. You will no longer receive presence from this contact.

Parameters

jid	The address to unsubscribe from.
msg	A message to send along with the request.
