No need for asm or anything like that, the protobuffer libraries already contain enough to do what you want to do. To create a new message definition, you can use DescriptorProto to create the message, put it in a FileDescriptorProto, and use FileDescriptor.buildFrom() to build it. Now you can get the descriptors out with FileDescriptor.getMessageTypes(). Once you have a message's Descriptor, you can parse messages using DynamicMessage.parseFrom(), and you can create new messages using DynamicMessage.Builder. - Adam -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.
