Interface Summary

Interface	Description
ClusterInfoService	Interface for a class used to gather information about a cluster at regular intervals
ClusterInfoService.Listener	Interface for listeners to implement in order to perform actions when new information about the cluster has been gathered
ClusterService	The cluster service allowing to both register for cluster state events (ClusterStateListener) and submit state update tasks (ClusterStateUpdateTask.
ClusterState.Custom
ClusterState.Custom.Factory<T extends ClusterState.Custom>
ClusterStateListener	A listener to be notified when a cluster state changes.
ClusterStateObserver.ChangePredicate
ClusterStateObserver.Listener
LocalNodeMasterListener	Enables listening to master changes events of the local node (when the local node becomes the master, and when the local node cease being a master).
TimeoutClusterStateListener	An exception to cluster state listener that allows for timeouts and for post added notifications.

Class Summary

Class	Description
AckedClusterStateUpdateTask<Response>	An extension interface to ClusterStateUpdateTask that allows to be notified when all the nodes have acknowledged a cluster state update request
ClusterChangedEvent
ClusterInfo	ClusterInfo is an object representing a map of nodes to DiskUsage and a map of shard ids to shard sizes, see InternalClusterInfoService.shardIdentifierFromRouting(String) for the key used in the shardSizes map
ClusterModule
ClusterName
ClusterNameModule
ClusterState
ClusterState.Builder
ClusterStateNonMasterUpdateTask	This is a marker interface to indicate that the task should be executed even if the current node is not a master.
ClusterStateObserver	A utility class which simplifies interacting with the cluster state in cases where one tries to take action based on the current state but may want to wait for a new state and retry upon failure.
ClusterStateObserver.EventPredicate
ClusterStateObserver.ValidationPredicate
ClusterStateUpdateTask	A task that can update the cluster state.
DiskUsage	Encapsulation class used to represent the amount of disk used on a node.
EmptyClusterInfoService	ClusterInfoService that provides empty maps for disk usage and shard sizes
InternalClusterInfoService	InternalClusterInfoService provides the ClusterInfoService interface, routinely updated on a timer.
ProcessedClusterStateNonMasterUpdateTask	A combination between ProcessedClusterStateUpdateTask and ClusterStateNonMasterUpdateTask to allow easy creation of anonymous classes
ProcessedClusterStateUpdateTask	An extension interface to ClusterStateUpdateTask that allows to be notified when the cluster state update has been processed.
TimeoutClusterStateUpdateTask	An extension interface to ClusterStateUpdateTask that allows to associate a timeout.
