[Boost-users] [Uuid] Portable binary serialization.

12 Mar 2010

      I'm interested in using the portable binary serialization code in  
[serialization]/example directory with Boost.Uuid.  I've noticed that  
there's a fall back template function for unrecognized types in  
portable_binary_iarchive.hpp:

101	    // default fall through for any types not specified here
102	    template<class T>
103	    void load(T & t){
104	        boost::intmax_t l;
105	        load_impl(l, sizeof(T));
106	        // use cast to avoid compile time warning
107	        t = static_cast<T>(l);
108	    }

that relies on the sizeof operator.  Short of replacing the sizeof  
operator with a templated switch:

//Code Sample 1
//Start code
template <typename T>
std::size_t my_size_of { return sizeof(T); }

tempate <>
std::size_t my_size_of<boost::uuids::uuid> { return  
boost::uuids::uuid::static_size(); }
//End code

or using macros ala:

//CodeSample 2
//Start

template <typename T>
std::size_t my_size_of(T const & t) { return sizeof(T); }

tempate <>
std::size_t my_size_of<boost::uuids::uuid>(boost::uuids::uuid const &) {  
return boost::uuids::uuid::static_size(); }

#define sizeof(x) my_size_of(x)
#include <boost_portable_binary_serialization>
#undef sizeof
//End

, is their something less instrusive I could do to make it work with  
Boost.Uuid?

Thanks,
