I've been working on a new data marshaling system for using template metaprogramming, and I was wondering if anyone could take a look at it and give me some feedback. The system allows the user to easily create packet definitions for objects (classes) by using the predefined serialization macros on member variables. The system provides serializers for: Compressed Integer String (char *) STL String Arbitrarily Sized Blocks (using memcpy) It also provides serializers for several higher level data structures: STL Vector Variable Sized Array Statically Sized Array Multiple choice Download the code here: http://nick.weihs.googlepages.com/grog_dm.zip
