Class RemoteRpcInvocation

java.lang.Object

org.apache.flink.runtime.rpc.messages.RemoteRpcInvocation

All Implemented Interfaces:

Serializable, RpcInvocation

public class RemoteRpcInvocation
extends Object
implements RpcInvocation, Serializable

Remote rpc invocation message which is used when the actor communication is remote and, thus, the message has to be serialized.

In order to fail fast and report an appropriate error message to the user, the method name, the parameter types and the arguments are eagerly serialized. In case the invocation call contains a non-serializable object, then an IOException is thrown.
