C++, function pointer to the template function pointer

Question

I am having a pointer to the common static method

class MyClass
{
  private:
    static double ( *pfunction ) ( const Object *, const Object *);
    ...
};
<

One thing you can do is have a copy of the template member function in the cpp file and point to that i.e.

template <+typename ElementType>
int PQueueHeap::compareFunction(ElementType First,ElementType Second)
{   
    if (First>Second) return 1; else if (First==Second) return 0; else return -1;
}

// you cannot point to above 

however you can point to

template <+typename ElementType>

int compareFunction(ElementType First,ElementType Second)
{

if (First>Second) return 1; else if (First==Second) return 0; else return -1;
} // No error and it works!
