Class IndexShardRoutingTable

org.elasticsearch.cluster.routing.IndexShardRoutingTable
All Implemented Interfaces:
<ShardRouting>
public class IndexShardRoutingTable extends implements <ShardRouting>
IndexShardRoutingTable encapsulates all instances of a single shard. Each Elasticsearch index consists of multiple shards, each shard encapsulates a disjoint set of the index data and each shard has one or more instances referred to as replicas of a shard. Given that, this class encapsulates all replicas (instances) for a single index shard.
