I have a set of classes, each of them being a subclass of a base class. I
need an array of subclasses, and I know which one to instantiate thanks to a
numeric or litteral ID. So, I think the solution which fits my needs is
Tobias Schwinger's Boost.Functional/Factory library.

Thanks for all y our quick answers.
