Making "announce" protected
in StaticBaseA
and StaticBaseB
might be part-way to doing what you want.
You then could not call StaticBaseB<NonDerived>::announce
from main as it would be inaccessible. You could call it from a class derived from StaticBaseB.
In other words:
template<class TDerived>
class StaticBaseA
{
protected:
static void announce()
{
std::cout << "do something" << std::endl;
}
};
template<class TDerived>
class StaticBaseB
{
protected:
static void announce()
{
std::cout << "do something else" << std::endl;
}
};
In Derived you have to promote "announce" to public.
class Derived : public StaticA<Derived>, public StaticB<Derived >
{
public:
using StaticA<Derived>::announce;
};
int main()
{
Derived::announce(); // legal and calls StaticBaseA::announce
NotDerived::announce(); // no such function
StaticBaseA< Derived >::announce(); // not accessible
StaticBaseB< Derived >::announce(); // also not accessible
StaticBaseA< NotDerived >::announce(); // not accessible
StaticBaseB< NotDerived >::announce(); // also not accessible
}
