Can C++ Constructors be templates?
- by Gokul
Hi,
I have non-template class with a templatized constructor. This code compiles for me. But i remember that somewhere i have referred that constructors cannot be templates. Can someone explain whether this is a valid usage?
typedef double Vector;
//enum Method {A, B, C, D, E, F};
struct A {};
class Butcher
{
public:
template <class Method>
Butcher(Method);
private:
Vector a, b, c;
};
template <>
Butcher::Butcher(struct A)
: a(2), b(4), c(2)
{
// a = 0.5, 1;
// b = -1, 1, 3, 2;
// c = 0, 1;
}
Thanks,
Gokul.
