How would these plain functions be different from final ones?
You would be able to redefine them in a derived class using
override to tell the compiler that it was intentional.
So the compiler would choose which function is called based on
the compile-time type of the class reference, instead of the
runtime type info? Inheritance without the polymorphism.
Twould be as in this C++, is that what you mean?
#include <iostream>
class A
{
public:
void foo() { std::cout << "This is A\n"; }
};
class B: A
{
public:
void foo() { std::cout << "This is B\n"; }
};
int main()
{
A* a = new A();
B* b = new B();
a->foo();
b->foo();
}
My, it was painful writing that!
