Method Detail

availableSession

void availableSession(ClientSession session,
                      Presence presence)

Notification message indicating that a session that was not available is now available. A session becomes available when an available presence is received. Sessions that are available will have a route in the routing table thus becoming eligible for receiving messages (in particular messages sent to the user bare JID).

Parameters:

session - the session that is now available.

presence - the received available presence.

unavailableSession

void unavailableSession(ClientSession session,
                        Presence presence)

Notification message indicating that a session that was available is no longer available. A session becomes unavailable when an unavailable presence is received. The entity may still be connected to the server and may send an available presence later to indicate that communication can proceed.

Parameters:

session - the session that is no longer available.

presence - the received unavailable presence.

presencePriorityChanged

void presencePriorityChanged(ClientSession session,
                             Presence presence)

Notification message indicating that the presence priority of a session has been modified. Presence priorities are used when deciding which session of the same user should receive a message that was sent to the user bare's JID.

Parameters:

session - the affected session.

presence - the presence that changed the priority.

presenceChanged

void presenceChanged(ClientSession session,
                     Presence presence)
