[protobuf] Re: Why does Protobuf generate outer classes for Java?

Java protobufs originally only had the option to have the outer class, which is consistent with some other languages' protocol buffers. We decided to add the "multiple files" option for users to have the option. We recommend using the multiple files option in most instances, but continue

We do not support typedefs in protobuf. We would like proto APIs to be as consistent as possible between languages, so we would not add a feature that is so C/C++ specific. If we were to do something like this, it would be a more generic version of type aliasing. See this thread

In protobuf, we can't store null strings so to denote a string that isn't set we use the empty string. For this reason, the parsing is returning false to tell you that there isn't a field there but as you're seeing will still parse as an empty string. On Wednesday, June 14, 2023 at 1:37:05 AM
