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.

メソッドの詳細

localNode

DiscoveryNode localNode()

addListener

void addListener(InitialStateDiscoveryListener listener)

removeListener

void removeListener(InitialStateDiscoveryListener listener)

nodeDescription

String nodeDescription()

setNodeService

void setNodeService(@Nullable
                    NodeService nodeService)

Here as a hack to solve dep injection problem...

setRoutingService

void setRoutingService(RoutingService routingService)

Another hack to solve dep injection problem..., note, this will be called before any start is called.

publish

void publish(ClusterChangedEvent clusterChangedEvent,
             Discovery.AckListener ackListener)

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...). The Discovery.AckListener allows to keep track of the ack received from nodes, and verify whether they updated their own cluster state or not.

startInitialJoin

void startInitialJoin()

Triggers the first join cycle
