Package org.apache.beam.sdk.fn.stream

Class ForwardingClientResponseObserver<ReqT,​RespT>

  • All Implemented Interfaces:
    org.apache.beam.vendor.grpc.v1p48p1.io.grpc.stub.ClientResponseObserver<RespT,​ReqT>, org.apache.beam.vendor.grpc.v1p48p1.io.grpc.stub.StreamObserver<ReqT>
    public final class ForwardingClientResponseObserver<ReqT,​RespT>
extends java.lang.Object
implements org.apache.beam.vendor.grpc.v1p48p1.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.
