Force type of C++ template

Question

I\'ve a basic template class, but I\'d like to restrain the type of the specialisation to a set of classes or types. e.g.:

template 
class          


        

Answer 1

Im not sure about this, but you could add another template specialization for double template

class MyClass
{
.../...
private:
    T* _p;
};

template  class MyClass
{};

which would work for your example, but not for the general case.

In general, I would add a compile assert to check for unwanted types.

Hope it helps.
