Interface Discovery

All Superinterfaces:

CloseableComponent, LifecycleComponent<Discovery>

All Known Implementing Classes:

LocalDiscovery, ZenDiscovery

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.

Field Summary

static ClusterBlock

NO_MASTER_BLOCK

Method Summary

void	addListener(InitialStateDiscoveryListener listener)
DiscoveryNode	localNode()
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)
void	setNodeService(NodeService nodeService) Here as a hack to solve dep injection problem...

publish

void publish(ClusterState clusterState)

Publish all the changes to the cluster from the master (can be called just by the master). The publish process should not publish this state to the master as well! (the master is sending it...).
