Since it doesn't really have a name +besides "protobuf," calling this directory "googlepb" seems like the +least confusing option, since it lives in the google::protobuf +namespace. + +We support writing into protobuf's generated classes (and hopefully +reading too, before long). We support both the open source protobuf +release and the Google-internal version (which is mostly the same +code, just in a different namespace). A single compile of upb can +support both (there are no conflicts thanks to function overloading). + +The internal version supports some features that are not supported in +the open-source release. Also, the internal version includes the +legacy "proto1" classes which we must support; thankfully this is +mostly relegated to its own separate file. + +Our functionality requires the full google::protobuf::Message +interface; we rely on reflection so we know what fields to read/write +and where to put them, so we can't support MessageLite. |
