Robert,
while trying to add serialization support for fusion sequences I came across the need to figure out whether a given type actually is an archive. Is there a boost::serialization::is_archive<> metafunction available? And if not, what's the best way to implement this?
Hmmm - I chuckled when I read this. It seems that I would be asking you this question rather than the other way around.
You're the serialization master, not me :-P
Giving it a tiny bit of thought leads me to wonder:
First thought is one could use something like is_base_derived to verify that it derived from from one of the common base classes. This solution would probably be sufficient for most practical purposes.
That would be sufficient for now I think. What are the base classes I could use to test against? Regards Hartmut
