How do i write defination of function 'get_as' in outside

Question

How do i write defination of function 'get_as' in outside

of class?

template <class C> class X
{
public:
template <class T, typename std::enable_if< ! std::is_same<double,T>::value>::type * = nullptr > void get_as(){
std::cout << "get as T" << std::endl;
}

template <class T, typename std::enable_if< std::is_same<double,T>::value>::type * = nullptr > void get_as(){
std::cout << "get as double" << std::endl;
}
};

I did that like this but it does not works

template <class C>
class X
{
public:
template <class T,void* >
void get_as();

};

template <class C>
template <class T, typename std::enable_if< ! std::is_same<double,T>::value>::type * =nullptr>
void X<C>::get_as()
{
std::cout << "get as T" << std::endl;
}

template <class C>
template <class T, typename std::enable_if< std::is_same<double,T>::value>::type * =nullptr>
void X<C>::get_as()
{
std::cout << "get as double" << std::endl;
}
