public interface Discovery
extends LifecycleComponent<Discovery>

A pluggable module allowing to implement discovery of other nodes, publishing of the cluster state to all nodes, electing a master of the cluster that raises cluster state change events.

Method Summary

void	addListener(InitialStateDiscoveryListener listener)
boolean	firstMaster() Is the discovery of this node caused this node to be the first master in the cluster.
java.lang.String	nodeDescription()
void	publish(ClusterState clusterState) Publish all the changes to the cluster from the master (can be called just by the master).
void	removeListener(InitialStateDiscoveryListener listener)
