public class OperationSetPersistentPresenceJabberImpl
extends AbstractOperationSetPersistentPresence<ProtocolProviderServiceJabberImpl>

The Jabber implementation of a Persistent Presence Operation set. This class manages our own presence status as well as subscriptions for the presence status of our buddies. It also offers methods for retrieving and modifying the buddy contact list and adding listeners for changes in its layout.
