Template partial specialization with multiple template argument error

Question

When I use template partial specialization on a class with one template argument, I can specialize a method like this:

#include 

template<         


        

Answer 1

You cannot partially specialise functions – this includes member functions. You can only partially specialise the whole class:

template< typename T, std::size_t Dim >
class Test
{
public:
  int foo()
  {
    return 0;
  }
};

template< typename T >
class test< T, 1 >
{
public:
  int foo()
  {
    return 1;
  }
};

(I’ve defined the functions inline here; that of course isn’t necessary.)
