All Implemented Interfaces:

Module, GroupEventListener, UserEventListener

public class RosterManager
extends BasicModule
implements GroupEventListener, UserEventListener

A simple service that allows components to retrieve a roster based solely on the ID of the owner. Users have convenience methods for obtaining a roster associated with the owner. However there are many components that need to retrieve the roster based solely on the generic ID owner key. This interface defines a service that can do that. This allows classes that generically manage resource for resource owners (such as presence updates) to generically offer their services without knowing or caring if the roster owner is a user, chatbot, etc.
