Template detects if T is pointer or class

Question

Considering the following code:

class MyClass
{
    ...
};

template 
class List
{
public:

    void insert(const Object & x)
             


        

Answer 1

void insert(const Object & x)
{
    M_insert(x, dispatcher::value> );
}

Inside List use a dispatcher

template  class dispatcher {};
using ObjectPtr   = dispatcher;
using ObjectValue = dispatcher;

then dispatch to M_insert:

void M_insert(const Object &p, ObjectPtr) { // Object is a pointer }
void M_insert(const Object &p, ObjectValue) { // Object is not a pointer }

Live example here. But, I'd encourage you to determine whether you really need that and possibly fix your design accordingly.
