UML representation for C/C++ function pointers

Question

What would be the best representation of a C/C++ function pointer (fp) in an UML structural diagram?

I\'m thinking about using an interface element, may be even if \'deg

Answer 1

Like your first example I would use a Classifier but hide it away in a profile. I think they've included it for clarity of the explaining the concept; but in practice the whole idea of stereotypes is abstract away details into profiles to avoid the 'noise' problem. EA is pretty good for handling Profiles.

Where I differ from your first example is that I would Classify the Primitive Type Stereotype not the Data Type stereotype. Data Type is a Domain scope object, while Primitive Type is an atomic element with semantics defined out side the scope of UML. That is not to say you cannot add notes, especially in the profile or give it a very clear stereotype name like functionPointer.
