Friendness and derived class
- by ereOn
Hi,
Let's say I have the following class hierarchy:
class Base
{
protected:
virtual void foo() = 0;
friend class Other;
};
class Derived : public Base
{
protected:
void foo() { /* Some implementation */ };
};
class Other
{
public:
void bar()
{
Derived* a = new Derived();
a->foo(); // Compiler error: foo() is protected within this context
};
};
I guess I could change it too a->Base::foo() but since foo() is pure virtual in the Base class, the call will result in calling Derived::foo() anyway.
However, the compiler seems to refuse a->foo(). I guess it is logical, but I can't really understand why. Am I missing something ? Can't (shouldn't) it handle this special case ?
Thank you.
