protocol-buffers

问题 In the following code i want to use a predefined protobuf message in c#. I found that I was able to write and use the method to take a method that has been created and make a byte[] : ContainerMessage containerMessage = new ContainerMessage(); containerMessage.Type = CommandType.Connect; containerMessage.Connect = new Connect(); containerMessage.Connect.ClientName = "TemporaryClientName"; byte[] stream = new byte[containerMessage.CalculateSize()]; using (Google.Protobuf.CodedOutputStream

问题 I'm perhaps overlooking something, but I'm attempting to wrestle protocol buffers into an easy method for providing extensions later. That seems a bit unclear so I'll jump directly into the problem. I am writing an assembly to support various tasks, one of which includes describing structured data. Perfect time to use protocol buffers. The primary class to use protocol buffers is called StateDefinition. Here's the .proto file I came up with for it: package Kannon.State; message

问题 I'm seeing some issues with compatibility between com.google.android.gms:play-services-auth:11.6.0 and com.android.support.test.espresso:espresso-core:3.0.1 when used as dependencies on an android library module I'm getting this error: Execution failed for task ':mylibrary:transformResourcesWithMergeJavaResForDebugAndroidTest'. More than one file was found with OS independent path 'protobuf.meta' when I try to execute ./gradlew :myLibrary:connectedAndroidTest Here's a barebones build.gradle

问题 I came across this blog post, which I found awesome and enlightening, showing how to do fixed-length framing of string messages sent to an Akka IO socket server. I have been working with an open source library I found here called ScalaBuff, which creates a nice thin layer on top of protocol buffer objects. The trouble I'm having is in adapting the blog author's (couldn't find a link to contact him directly) code to take the length (4-byte sequence) and then the protobuf byte array. I can

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 2 years ago . I'm looking for a solution for serializing of c++ packets to a network stream. I have seen many posts here refering people to: ACE Google Protocol Buffers Boost::Serialization Qt ::QDataStream My Requirements/ Constraints: The solution must be unaware of LitteEndian/BigEndian. Machine Architecture x86/x64 and

问题 I'm having differences of the outputs when comparing a model with its stored protobuf version (via this conversion script). For debugging I'm comparing both layers respectively. For the weights and the actual layer output during a test sequence I receive the identical outputs, thus I'm not sure how to access the hidden layers. Here is how I load the layers input = graph.get_tensor_by_name("lstm_1_input_1:0") layer1 = graph.get_tensor_by_name("lstm_1_1/kernel:0") layer2 = graph.get_tensor_by

问题 I have a server written in Java and client written in PHP. How can client catch exception from server if anything goes wrong? I can't find anything about exception handling in gRPC documentation. Thank you! 回答1: For handled exceptions, call responseObserver.onError() . If you pass in a StatusRuntimeException or StatusException (generally created via status.asRuntimeException() ) the status code and description will be communicated to the client. Unhandled exceptions within a callback will

问题 I seem unable to find a way to verify the value of a field inside a protobuf message without explicitly invoking its getter. I see examples around that make usage of Descriptors.FieldDescriptor instances to reach inside the message map, but they are either iterator-based or driven by field number. Once I have the map: Map<Descriptors.FieldDescriptor, Object> allFields = myMsg.getAllFields(); how can I get the value of field "fieldXyz" ? I know that I can use myMsg.getFieldXyz() , but this is

问题 Given a protocol buffer encoded Stream or byte[] but NOT knowing the object type itself, how can we print the skeleton of the message? The use case is for debugging IO that's protobuf based, for root cause analysis. If there are existing tools that can parse the raw Protocol Buffer byte stream from a binary file - that would be great! An alternative could be using the ProtoBuf.NET class ProtoReader() to keep chugging along till we hit the error but the usage of ProtoReader() isn't clear. I
