Class ServerStoredContactListJabberImpl

java.lang.Object

net.java.sip.communicator.impl.protocol.jabber.ServerStoredContactListJabberImpl

public class ServerStoredContactListJabberImpl
extends java.lang.Object

This class encapsulates the Roster class. Once created, it will register itself as a listener to the encapsulated Roster and modify it's local copy of Contacts and ContactGroups every time an event is generated by the underlying framework. The class would also generate corresponding sip-communicator events to all events coming from smack.
