public class OperationSetPersistentPresenceRssImpl
extends AbstractOperationSetPersistentPresence<ProtocolProviderServiceRssImpl>

A RSS implementation of a persistent presence operation set. In order to simulate server persistence, this operation set would simply accept all unresolved contacts and resolve them immediately. A real world protocol implementation would save it on a server using methods provided by the protocol stack.
