A robust reflection/metadata system in C++ can be extremely powerful and has many applications, particularly in game programming. It can facilitate sophisticated debug output and logging, trivial factory implementation, automatic serialization and deserialization for any arbitrary object, automatic binding to a GUI system, and even automatic binding of objects and functions to a scripting language (both Lua and Python are popular). The typeinfo/RTTI system currently in C++ however is simply not up to this level of functionality, so a more sophisticated solution is necessary. In this talk, I will implement a simple, yet powerful, meta reflection system in C++, completely from scratch, and using test-driven development. I will also show how I leverage a similar system in my own game engine. Finally, I promise there will be no more than three PowerPoint slides.
