C++ protobuf mergefrom
Don't override MergeFrom (). You will break parts of the protobuf implementation that expect MergeFrom () to work a certain way. Instead, put your reflection-based code as a stand-alone function -- there is no reason it specifically needs to be in the MergeFrom () method, since you can have your code that calls this call the new function instead. WebSep 8, 2008 · To clarify: In my original message I was saying that you should call isInitialized () on the builder returned by mergeFrom (), to make sure the parsed message is complete, before you call build (). Ah. Now isInitialized () is returning true, though I'm still having problems deserializing.

WebApr 12, 2024 · ProtoBuf (Protocol Buffers) is the name of the binary serialization format used by Google for much of their data exchange. It is designed to be: small in size (efficient data storage, far smaller than XML); cheap to process (at the client and server); platform independent (portable between different programming architectures); WebRepeatedField and RepeatedPtrField are used by generated protocol message classes to manipulate repeated fields. These classes are very similar to STL's vector, but include a number of optimizations found to be useful specifically in the case of Protocol Buffers. RepeatedPtrField is particularly different from STL vector as it manages ownership ...
