I can't figure out how to override serializating enums (and arrays) - without hacking the source code, that is. save_enum_type is defined in boost/archive/detail/oserializer.hpp, and converts them into ints (btw, would longs be safer?). I tried defining a serialize function and specifying the implementation level to object_serializable, but that didn't work (and given how it's defined and used, there seems to be no way of overriding via template specialization). Perhaps save_enum_type and save_array_type could be put into a separate header (out of the archive/detail and maybe into boost/serialization along with vector.hpp, etc)? BTW, thanks for the great library! --craig ____________________________________________________________________________________ Any questions? Get answers on any topic at www.Answers.yahoo.com.
