org.apache.flink.runtime.rpc

Class FencedRpcEndpoint<F extends Serializable>

java.lang.Object

org.apache.flink.runtime.rpc.RpcEndpoint

org.apache.flink.runtime.rpc.FencedRpcEndpoint<F>

Type Parameters:

F - type of the fencing token

All Implemented Interfaces:

AutoCloseable, RpcGateway, AutoCloseableAsync

Direct Known Subclasses:

Dispatcher, JobMaster, ResourceManager

public abstract class FencedRpcEndpoint<F extends Serializable>
extends RpcEndpoint

Base class for fenced RpcEndpoint. A fenced rpc endpoint expects all rpc messages being enriched with fencing tokens. Furthermore, the rpc endpoint has its own fencing token assigned. The rpc is then only executed if the attached fencing token equals the endpoint's own token.
