Examples with GrpcResponseMetadata com.google.api.gax.grpc.GrpcResponseMetadata used on opensource projects

Example 1 with GrpcResponseMetadata

use of com.google.api.gax.grpc.GrpcResponseMetadata in project java-bigtable by googleapis.

the class HeaderTracerUnaryCallable method futureCall.

@Override
public ApiFuture futureCall(RequestT request, ApiCallContext context) {
    // tracer should always be an instance of BigtableTracer
    if (RpcViews.isGfeMetricsRegistered() && context.getTracer() instanceof BigtableTracer) {
        final GrpcResponseMetadata responseMetadata = new GrpcResponseMetadata();
        final ApiCallContext contextWithResponseMetadata = responseMetadata.addHandlers(context);
        HeaderTracerUnaryCallback callback = new HeaderTracerUnaryCallback((BigtableTracer) context.getTracer(), responseMetadata);
        ApiFuture<ResponseT> future = innerCallable.futureCall(request, contextWithResponseMetadata);
        ApiFutures.addCallback(future, callback, MoreExecutors.directExecutor());
        return future;
    } else {
        return innerCallable.futureCall(request, context);
    }
}

Example 2 with GrpcResponseMetadata

use of com.google.api.gax.grpc.GrpcResponseMetadata in project java-bigtable by googleapis.

the class HeaderTracerStreamingCallable method call.

@Override
public void call(RequestT request, ResponseObserver<ResponseT> responseObserver, ApiCallContext context) {
    final GrpcResponseMetadata responseMetadata = new GrpcResponseMetadata();
    // tracer should always be an instance of bigtable tracer
    if (RpcViews.isGfeMetricsRegistered() && context.getTracer() instanceof BigtableTracer) {
        HeaderTracerResponseObserver<ResponseT> innerObserver = new HeaderTracerResponseObserver<>(responseObserver, (BigtableTracer) context.getTracer(), responseMetadata);
        innerCallable.call(request, innerObserver, responseMetadata.addHandlers(context));
    } else {
        innerCallable.call(request, responseObserver, context);
    }
