Class ForwardingClientResponseObserver<ReqT,RespT>

java.lang.Object

org.apache.beam.sdk.fn.stream.ForwardingClientResponseObserver<ReqT,RespT>

All Implemented Interfaces:

org.apache.beam.vendor.grpc.v1p13p1.io.grpc.stub.ClientResponseObserver<RespT,ReqT>, org.apache.beam.vendor.grpc.v1p13p1.io.grpc.stub.StreamObserver<ReqT>

public final class ForwardingClientResponseObserver<ReqT,RespT>
extends java.lang.Object
implements org.apache.beam.vendor.grpc.v1p13p1.io.grpc.stub.ClientResponseObserver<RespT,ReqT>

A ClientResponseObserver which delegates all StreamObserver calls.

Used to wrap existing StreamObservers to be able to install an onReadyHandler.

This is as thread-safe as the underlying stream observer that is being wrapped.
