tigase.pubsub.cluster

Class ClusteredNodeStrategy

java.lang.Object

tigase.pubsub.cluster.AbstractStrategy

tigase.pubsub.cluster.ClusteredNodeStrategy

All Implemented Interfaces:

tigase.kernel.beans.Initializable, tigase.kernel.beans.UnregisterAware, StrategyIfc

public class ClusteredNodeStrategy
extends AbstractStrategy
implements StrategyIfc

ClusteredNodeStrategy - all pubsub nodes are shared between all cluster nodes, which implies forwarding of packet information across the cluster with the exception of create/remove operation on nodes (to avoid race conditions).
