org.neo4j.com.Client<Master>

org.neo4j.kernel.ha.com.slave.MasterClient153

All Implemented Interfaces:

org.jboss.netty.channel.ChannelPipelineFactory, Master, MasterClient, org.neo4j.kernel.lifecycle.Lifecycle

public class MasterClient153
extends org.neo4j.com.Client<Master>
implements Master, MasterClient

The Master a slave should use to communicate with its master. It serializes requests and sends them to the master, more specifically MasterServer (which delegates to MasterImpl on the master side.
