I went back a looked at it again. I though the something very close to the following was already in there extended_type_info *eti = extended_type_info("MY_CLASS"); void * v = eti->create_instance(); But alas - my memory was wrong. The basic machinery is there and the functional equivalent to the above is certainly there, but its intertwined sith some other stuff like creation of objects on the stack, non-default arguments, and other stuff. I remember I was thinking about adding a little bit onto extended_type_info to support this but I realise now I never got around to it. maybe someday. Robert Ramey Wu Yinghui, Freddie wrote:
Note that a component of the serialization library "extended_type_info" addresses this issue (as it must) in order to de-serialize pointers. You might look in the serialization documentation.

Frankly speaking, I've been researching on this topic as well. Most of the current libraries (e.g. Reflex) uses external programs/scripts to general the "stub" program for reflection support. This is not acceptable for our current environment.
Boost.Serialization was a very good candidate, though a little bit difficult to use--It provides the necessary support all under the hood of C++ and C++ alone. Nonetheless, though I've inspected "extended_type_info" reference in the manual a number of times, I'm sorry that I cannot see how to achieve what Rob Caldecott wanted using it.
Maybe you can shed some light on this? TIA!
Cheers,
Freddie

Can Boost help me to achieve this?
