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 *);
    ...
};
<         


        

Answer 1

In the second case, getA is not a function anymore but a function template, and you can't have a pointer to function template.

What you can do is have pfunction point to a particular getA instance (ie: for T = int) :

class MyClass
{
    static double (*pfunction)(const Object *, const Object *);
};

double (*MyClass::pfunction)(const Object *o1, const Object *o2)  = &SomeClass::getA;

But I don't think there is a way to get pfunction to point on any possible instance of getA.
