11.8 Member access control [class.access]
11.8.6 Access to virtual functions [class.access.virt]
The access rules ([class.access]) for a virtual function are determined by its declaration and are not affected by the rules for a function that later overrides it.
[Example 1: class B {public:virtual int f();};
class D : public B {private:int f();};
void f() { D d; B* pb = &d; D* pd = &d;
pb->f(); // OK, B::f() is public, D::f() is invoked pd->f(); // error: D::f() is private} â end example]
Access is checked at the call point using the type of the expression used to denote the object for which the member function is called (B* in the example above).
The access of the member function in the class in which it was defined (D in the example above) is in general not known.
