Class RoutingNode

java.lang.Object

org.elasticsearch.cluster.routing.RoutingNode

All Implemented Interfaces:

Iterable<ShardRouting>

public class RoutingNode
extends Object
implements Iterable<ShardRouting>

A RoutingNode represents a cluster node associated with a single DiscoveryNode including all shards that are hosted on that nodes. Each RoutingNode has a unique node id that can be used to identify the node.
