Package org.apache.flink.runtime.rpc.pekko

Class FencedPekkoInvocationHandler<F extends Serializable>

java.lang.Object

org.apache.flink.runtime.rpc.pekko.FencedPekkoInvocationHandler<F>

Type Parameters:

F - type of the fencing token

All Implemented Interfaces:

InvocationHandler, org.apache.flink.runtime.rpc.FencedRpcGateway<F>, org.apache.flink.runtime.rpc.MainThreadExecutable, org.apache.flink.runtime.rpc.RpcGateway, org.apache.flink.runtime.rpc.RpcServer, org.apache.flink.runtime.rpc.StartStoppable

public class FencedPekkoInvocationHandler<F extends Serializable>
extends Object
implements org.apache.flink.runtime.rpc.MainThreadExecutable, org.apache.flink.runtime.rpc.FencedRpcGateway<F>

Fenced extension of the PekkoInvocationHandler. This invocation handler will be used in combination with the FencedRpcEndpoint. The fencing is done by wrapping all messages in a FencedMessage.
