Detailed Description

The QXmppRosterManager class provides access to a connected client's roster.

Note: Its object should not be created using its constructor. Instead QXmppClient::findExtension<QXmppRosterManager>() should be used to get the instantiated object of this class.

It stores all the Roster and Presence details of all the roster entries (that is all the bareJids) in the client's friend's list. It provides the functionality to get all the bareJids in the client's roster and Roster and Presence details of the same.

After the QXmpp connected successfully to the XMPP server the signal QXmppClient::connected() is emitted and the roster is requested from the server. Once QXmpp receives the roster the signal QXmppRosterManager::rosterReceived() is emitted and after that the methods of this class can be used to get the roster entries.

QXmppRosterManager::isRosterReceived() can be used to find out whether the roster has been received yet.

The itemAdded(), itemChanged() and itemRemoved() signals are emitted whenever roster entries are added, changed or removed.

The presenceChanged() signal is emitted whenever the presence for a roster item changes.

Constructor & Destructor Documentation

◆ QXmppRosterManager()

QXmppRosterManager::QXmppRosterManager ( QXmppClient * client )

Constructs a roster manager.

Member Function Documentation

◆ acceptSubscription

bool QXmppRosterManager::acceptSubscription	(	const QString &	bareJid,
		const QString &	reason = `{}`
	)

slot

Accepts an existing subscription request or pre-approves future subscription requests.

You can call this method in reply to the subscriptionRequest() signal or to create a pre-approved subscription.

Note: Pre-approving subscription requests is only allowed, if the server supports RFC6121 and advertises the 'urn:xmpp:features:pre-approval' stream feature.

See also: QXmppStreamFeatures::preApprovedSubscriptionsSupported()

◆ addItem

bool QXmppRosterManager::addItem	(	const QString &	bareJid,
		const QString &	name = `{}`,
		const QSet< QString > &	groups = `{}`
	)

slot

Adds a new item the roster without sending any subscription requests.

As a result, the server will initiate a roster push, causing the itemAdded() or itemChanged() signal to be emitted.

Parameters

bareJid
name	Optotional name for the item.
groups	Optional groups for the item.

◆ addRosterItem()

QXmppTask< QXmppRosterManager::Result > QXmppRosterManager::addRosterItem	(	const QString &	bareJid,
		const QString &	name = `{}`,
		const QSet< QString > &	groups = `{}`
	)

Adds a new item to the roster without sending any subscription requests.

As a result, the server will initiate a roster push, causing the itemAdded() or itemChanged() signal to be emitted.

Parameters

bareJid
name	Optional name for the item.
groups	Optional groups for the item.

Since: QXmpp 1.5

◆ getAllPresencesForBareJid()

QMap< QString, QXmppPresence > QXmppRosterManager::getAllPresencesForBareJid ( const QString & bareJid ) const

Get all the presences of all the resources of the given bareJid. A bareJid can have multiple resources and each resource will have a presence associated with it.

Parameters

bareJid as a QString

Returns: Map of resource and its respective presence QMap<QString, QXmppPresence>

◆ getPresence()

QXmppPresence QXmppRosterManager::getPresence	(	const QString &	bareJid,
		const QString &	resource
	)		const

Get the presence of the given resource of the given bareJid.

Parameters

bareJid	as a QString
resource	as a QString

Returns: QXmppPresence

◆ getResources()

QStringList QXmppRosterManager::getResources ( const QString & bareJid ) const

Get all the associated resources with the given bareJid.

Parameters

bareJid as a QString

Returns: list of associated resources as a QStringList

◆ getRosterBareJids()

QStringList QXmppRosterManager::getRosterBareJids ( ) const

Function to get all the bareJids present in the roster.

Returns: QStringList list of all the bareJids

◆ getRosterEntry()

QXmppRosterIq::Item QXmppRosterManager::getRosterEntry ( const QString & bareJid ) const

Returns the roster entry of the given bareJid. If the bareJid is not in the database and empty QXmppRosterIq::Item will be returned.

Parameters

bareJid as a QString

◆ isRosterReceived()

bool QXmppRosterManager::isRosterReceived ( ) const

Function to check whether the roster has been received or not.

On disconnecting this is reset to false if no stream management is used by the client and so the stream cannot be resumed later.

Returns: true if roster received else false

◆ itemAdded

void QXmppRosterManager::itemAdded ( const QString & bareJid )

signal

This signal is emitted when the roster entry of a particular bareJid is added as a result of roster push.

◆ itemChanged

void QXmppRosterManager::itemChanged ( const QString & bareJid )

signal

This signal is emitted when the roster entry of a particular bareJid changes as a result of roster push.

◆ itemRemoved

void QXmppRosterManager::itemRemoved ( const QString & bareJid )

signal

This signal is emitted when the roster entry of a particular bareJid is removed as a result of roster push.

◆ refuseSubscription

bool QXmppRosterManager::refuseSubscription	(	const QString &	bareJid,
		const QString &	reason = `{}`
	)

slot

Refuses a subscription request.

You can call this method in reply to the subscriptionRequest() signal.

◆ removeItem

bool QXmppRosterManager::removeItem ( const QString & bareJid )

slot

Removes a roster item and cancels subscriptions to and from the contact.

As a result, the server will initiate a roster push, causing the itemRemoved() signal to be emitted.

Parameters

bareJid

◆ removeRosterItem()

QXmppTask< QXmppRosterManager::Result > QXmppRosterManager::removeRosterItem ( const QString & bareJid )

Removes a roster item and cancels subscriptions to and from the contact.

As a result, the server will initiate a roster push, causing the itemRemoved() signal to be emitted.

Parameters

bareJid

Since: QXmpp 1.5

◆ renameItem

bool QXmppRosterManager::renameItem	(	const QString &	bareJid,
		const QString &	name
	)

slot

Renames a roster item.

As a result, the server will initiate a roster push, causing the itemChanged() signal to be emitted.

Parameters

bareJid
name

◆ renameRosterItem()

QXmppTask< QXmppRosterManager::Result > QXmppRosterManager::renameRosterItem	(	const QString &	bareJid,
		const QString &	name
	)

Renames a roster item.

◆ rosterReceived

void QXmppRosterManager::rosterReceived ( )

signal

This signal is emitted when the Roster IQ is received after a successful connection. That is the roster entries are empty before this signal is emitted. One should use getRosterBareJids() and getRosterEntry() only after this signal has been emitted.

Note: If the previous stream could be resumed, this signal is not emitted since QXmpp 1.4. Changes since the last connection are reported via the itemAdded(), itemChanged() and itemRemoved() signals.

◆ subscribeTo()

QXmppTask< QXmpp::SendResult > QXmppRosterManager::subscribeTo	(	const QString &	bareJid,
		const QString &	reason = `{}`
	)

Requests a subscription to the given contact.

As a result, the server will initiate a roster push, causing the itemAdded() or itemChanged() signal to be emitted.

Since: QXmpp 1.5

◆ subscriptionReceived

void QXmppRosterManager::subscriptionReceived ( const QString & bareJid )

signal

This signal is emitted when a contact asks to subscribe to your presence.
