Example 1 with RaftClientReplyProto

use of org.apache.ratis.proto.RaftProtos.RaftClientReplyProto in project incubator-ratis by apache.

the class GrpcClientRpc method sendRequest.

    final StreamObserver<RaftClientRequestProto> requestObserver = proxy.unorderedWithTimeout(new StreamObserver<RaftClientReplyProto>() {

        @Override
        public void onNext(RaftClientReplyProto value) {
