Package org.elasticsearch.client

Interface Client

All Superinterfaces:

AutoCloseable, Closeable, ElasticsearchClient, org.elasticsearch.core.Releasable

All Known Implementing Classes:

AbstractClient, FilterClient, NodeClient, OriginSettingClient, ParentTaskAssigningClient, RestCancellableNodeClient

public interface Client
extends ElasticsearchClient, org.elasticsearch.core.Releasable

A client provides a one stop interface for performing actions/operations against the cluster.

All operations performed are asynchronous by nature. Each action/operation has two flavors, the first simply returns an ActionFuture, while the second accepts an ActionListener.

A client can be retrieved from a started Node.
