I would recommend using the writeDelimitedTo(OutputStream) and parseDelimitedFrom(InputStream) methods on Message objects. writeDelimitedTo writes the length of the message before the message itself; parseDelimitedFrom then uses that length to read only one message and no farther. This allows multiple messages to be written to a single OutputStream to then be parsed separately. For more information, … Read more
There is another possibility, if you are running a python 2.7.11 or other similar versions, sudo pip install protobuf is ok. But if you are in a anaconda environment, you should use conda install protobuf
Another option is (I think; it’s been a while): Foo.Builder fooBuilder = foo.toBuilder(); fooBuilder.getBarBuilder().getBazBuilder().getQuuxBuilder() .setNewThing(newThing); newFoo = fooBuilder.build(); Note that this isn’t any more efficient; you’re still making copies of foo, bar, baz, and quux.
Based on this proto file. syntax = “proto3”; package messages; import “google/protobuf/struct.proto”; service UserService { rpc SendJson (SendJsonRequest) returns (SendJsonResponse) {} } message SendJsonRequest { string UserID = 1; google.protobuf.Struct Details = 2; } message SendJsonResponse { string Response = 1; } I think it is a good solution to use the google.protobuf.Struct type. The … Read more
Take a look at the readme which describes how to add additional paths. By default, intellij-protobuf-editor uses the project’s configured source roots as protobuf import paths. If this isn’t correct, you can override these paths in Settings > Languages & Frameworks > Protocol Buffers. Uncheck “Configure automatically” and add whichever paths you need. In your … Read more
If you are looking for user facing interaction, stick with xml. It has more support, understanding, and general acceptance currently. If it’s internal, I would say that protocol buffers are a great idea. Maybe in a few years as more tools come out to support protocol buffers, then start looking towards that for a public … Read more
No, you’re doing the right thing. Here’s a snippet of my protocol buffer (details omitted for brevity): message DemandSummary { required uint32 solutionIndex = 1; required uint32 demandID = 2; } message ComputeResponse { repeated DemandSummary solutionInfo = 3; } …and the C++ to fill up ComputeResponse::solutionInfo: ComputeResponse response; for ( int i = 0; … Read more
Every proto class possess a DESCRIPTOR class variable that can be used to inspect the fields of corresponding protobuf messages. Have a look at the documentation of the Descriptor and FieldDescriptor classes for more details. Here is a simple example to get the FieldDescriptors of all the fields in message into a list: res = … Read more
ProfaneDB: http://profanedb.gitlab.io “ProfaneDB is a gRPC interface between Protocol Buffers and RocksDB” P.S: Though the question was asked 10 years ago I still find it very relevant, specially with the ascension of gRPC. Hope that can be of help.
