tigase.muc.cluster

Class AbstractClusteredRoomStrategy

java.lang.Object

tigase.muc.cluster.AbstractStrategy

tigase.muc.cluster.AbstractClusteredRoomStrategy

All Implemented Interfaces:

InMemoryMucRepositoryClustered.RoomListener, StrategyIfc, tigase.muc.Room.RoomListener, tigase.muc.Room.RoomOccupantListener

Direct Known Subclasses:

ClusteredRoomStrategy, ClusteredRoomStrategyNoPresence, ClusteredRoomStrategyV2

public abstract class AbstractClusteredRoomStrategy
extends AbstractStrategy
implements StrategyIfc, InMemoryMucRepositoryClustered.RoomListener, tigase.muc.Room.RoomListener

AbstractClusteredRoomStrategy implements strategy which allows to create rooms with large number of occupants as each cluster node will process packets related only to occupants connected to this node. (Base class for strategies implementations using clustered room strategy) Limitations: - every room needs to be persistent - possible issues with changing affiliations or room configuration
