Reference Guides

Reference documentation for working with protocol buffer classes in C++, Java, Python, Go, C#, Objective-C, Ruby, PHP, and Dart, as well as some reference documentation for Protocol Buffers itself.

This section contains reference documentation for working with protocol buffer classes in C++, Java, Python, Go, C#, Objective-C, Ruby, PHP, and Dart, as well as some reference documentation for Protocol Buffers itself. The documentation for each language includes (where available):

  • A reference guide to the code generated by the protocol buffer compiler from your .proto files.
  • Generated API documentation for the provided source code.
