Need info on Template specialisation

[Ganesh]

I have a question regarding template specialisation.

Assume I have a generic template class

template <class S, class T>

class A{

void f() {

// Some code here

}

}

I want to specialise the function f() for say A<int, S>.

Do I need to specialise the entire class.

If else how do i specialise just this fn/?

Yes, you do.

You cannot. No partial specialisations of function templates are allowed.
A simple way would be to overload 'f' in the class.

No,if you want to explicitly specialize the function:

template<>
void A<int,float>::f()
{
// blahblah
}

Still,there is no way to"partially specialize the function for the class.

Just like Victor said, overload.Or make the function templated if the design
allows.
