Hi,

I want to calculate exactly how much space it is needed to serialize a number of objects. What I'm thinking is another class that implements the Saving Archive concept and only invokes sizeof() rather than actually writing anything.

From what I understand I should overload the << and & operators for this class to call save() or serialize() on the object, unless it is a POD (in which case the size is already known).

Has this been done before?

Thanks
