Example 1 with Downstream

use of org.apache.skywalking.apm.network.proto.Downstream in project incubator-skywalking by apache.

the class GRPCNoServerTest method main.

public static void main(String[] args) throws InterruptedException {
    ManagedChannelBuilder<?> channelBuilder = NettyChannelBuilder.forAddress("127.0.0.1", 8080).nameResolverFactory(new DnsNameResolverProvider()).maxInboundMessageSize(1024 * 1024 * 50).usePlaintext(true);

    TraceSegmentServiceGrpc.TraceSegmentServiceStub serviceStub = TraceSegmentServiceGrpc.newStub(channel);
    final Status[] status = { null };
    StreamObserver<UpstreamSegment> streamObserver = serviceStub.collect(new StreamObserver<Downstream>() {

        @Override
        public void onNext(Downstream value) {
        }

        @Override
        public void onError(Throwable t) {
            status[0] = ((StatusRuntimeException) t).getStatus();
        }

        @Override
        public void onCompleted() {
        }
    });
    streamObserver.onNext(null);
    streamObserver.onCompleted();
