Detecting Inheritence during compile time
- by Jagannath
I am unable to figure out why this code is returning false. I had the first version of partial specialization. It did not work, I tried with the second version. It did not work either.
UPDATE: I wanted to check if "Derived" is publicly derived from "Base".
template<class TBase, class TDerived>
struct IsDerived
{
public:
enum { isDerived = false };
};
template<class TBase>
struct IsDerived<TBase, TBase>
{
public:
enum { isDerived = true };
};
template<class TBase>
struct IsDerived<TBase&, TBase&>
{
public:
enum { isDerived = true };
};
int main()
{
cout << ((IsDerived<Base&, Derived&>::isDerived) ? "true" : "false")
<< endl;
cout << ((IsDerived<const Derived*, const Base*>::isDerived) ?
"true" : "false") << endl;
}
