C++ template partial specialization - specializing one member function only

Question

Bumped into another templates problem:

The problem: I want to partially specialize a container-class (foo) for the case that the objects are pointers, and i want to

Answer 1

Second solution (correct one)

template 
class foo
{
public:
    void addSome    (T o) { printf ("adding that object..."); } 
    void deleteSome(T o) { deleteSomeHelper()(o); }
protected:
    template 
    struct deleteSomeHelper { void operator()(TX& o) { printf ("deleting that object..."); } };
    template 
    struct deleteSomeHelper { void operator()(TX*& o) { printf ("deleting that PTR to an object..."); } };
};

This solution is valid according to Core Issue #727.

First (incorrect) solution: (kept this as comments refer to it)

You cannot specialize only part of class. In your case the best way is to overload function deleteSome as follows:

template 
class foo
{
public:
    void addSome    (T o) { printf ("adding that object..."); }
    void deleteSome (T o) { printf ("deleting that object..."); }
    void deleteSome (T* o) { printf ("deleting that object..."); }
};
