Member Function Pointer...

Well, this is starting to annoy me and now it is preventing my project from continuing on. I want to have member function pointers that can still access the members of the class. For example:

Code:

---

class FOO
{
private:
        int a;

public:
        void TEST() { return a; }; // how do I get a pointer to this?
};

---

I know this isn't possible (without the function being static), but what other alternatives are there (not including global variables, if possible)?

Thanks.

Code:

---

class FOO
{
private:
        int a;

public:
        int TEST() { return a; }; // how do I get a pointer to this?
};



int _tmain(int argc, _TCHAR* argv[])
{
  FOO afoo;
  int (FOO::*fp)()= &FOO::TEST;

  (afoo.*fp)();

  return 0;
}

Unlike a normal pointer, which points at an absolute address, a "pointer to member" is relative to some object. A "pointer to member" carries no information about the object it will act on.

On its own, therefore, a pointer to member is unusable. The second bit of information needed is the object it is relative to. Hence the need for "(anObject.*a_member_pointer)()" method of use.
