Interface Client

All Superinterfaces:

java.lang.AutoCloseable, java.io.Closeable, ElasticsearchClient, Releasable

All Known Implementing Classes:

AbstractClient, FilterClient, NodeClient, ParentTaskAssigningClient, TransportClient

public interface Client
extends ElasticsearchClient, 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 either be retrieved from a Node started, or connected remotely to one or more nodes using TransportClient.

Node.client(), TransportClient
