Everything that I've been trying has been failing completely so I'm wondering if there is something that I missing or doing wrong.
To summarize, I have an Any message (let's call it mA) that I know contains a certain other specific message (call it messageTypeB). If I create an instance of messageTypeB (call it mB) and mA.UnpackTo(&mB) it fails. If I use the mA.Is<messageTypeB>() method it also returns false. If I compare mA.type_url() to mB.GetDescriptor()->full_name() they differ only in that the former has "type.googleapis.com/" at the front. So it seems that they do/should be corresponding to the same type. Yet the Is() method still says they don't. Just to see what would happen I tried creating a new Any object (call it mANew) from mA and use set_type_url() to set the url to exactly the string that I'm getting back from mB, but even then mANew.Is<messageTypeB>() returns false. Sometimes code speaks louder than words so here is an example of what I'm doing that seems like it should work but isn't: const ::vthree::protobuf::Any& anyMessage = parametricAttribution.layer_specific_attribution(); const std::string anyUrl = anyMessage.type_url(); // anyUrl is "type.googleapis.com/com.here.pb.hdmap.platform.v1.core.LinkParametricAttributionList" ::com::here::pb::hdmap::platform::v1::core::LinkParametricAttributionList coreLinkParametricAttributionList; const std::string aName = coreLinkParametricAttributionList.GetDescriptor()->full_name(); // aName is "com.here.pb.hdmap.platform.v1.core.LinkParametricAttributionList" if (anyMessage.Is<::com::here::pb::hdmap::platform::v1::core::LinkParametricAttributionList>()) { // It never gets in here. } So now I'm thoroughly baffled (and going a little crazy). When I ask the message for a string telling me type it is, it tells me that it is of a certain type. But if I use the Is() method with that type, it returns false. Even if I set the type_url() string to exactly match what I get from the descriptor of the type that I'm trying to unpack into it still says it's not that type. Has anybody else been using Any objects in C++ and had success? If so, were you doing anything different than what I've shown here? Elsewhere at my company we are using these same protobuf binary files in Java and having no problems so either I'm missing something here or the problem might be specific to the C++ libraries. (For reference we're using Beta-1 but it didn't seem like Beta-2 offered any changes that would be related.) -Justin -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.
