c++ - How to force template <class> to be derived from BaseClassA?

Question

Is there any possibility to force a template to be from a certain base class so that I can call the base class function?

template <class T>
void SomeManager::Add(T)
{
    T->CallTsBaseClassFunction();
    //... do other stuff
}

Answer 1

Sure, you can combine type traits with SFINAE:

#include <type_traits>

template <class T>
typename std::enable_if<std::is_base_of<your_base_class, T>::value, void>::type
SomeManager::Add(T)
{
    T->CallTsBaseClassFunction();
    //... do other stuff
}

Although I don't really see the benefit here.
