Re: Hello everybody, I have something to share about the shared_ptr class

Accepting the kindly advices from dear members (Rob, Andrey, Seth and others),
I just updated the code with disposing version of rcgc_ptr (shared is removed to avoid misunderstandings)
New added class is called rcgc_d_ptr.

rcgc_ptr uses the dtor and would call the dtor multiple times of the reference object.

rcgc_d_ptr needs the class to have a function named disposing() where all rcgc_d_ptr wrapped fields
should call their .dispose() method (not ->dispose() method).


class D
{
public:
    D() :_ptr_outC(){}
    ~D() {
        std::cout << "dtor for object of D:" << std::hex << this << std::endl;
    }
public:
    void disposing() {
        //Should NOT be this->_ptr_outC->disposing()
        //which will lead to this function itself (direct/indirect-recursion).
        //NOTICE:Don't call self directly or indirectly!
        this->_ptr_outC.disposing();
    }
public:
    rcgc_d_ptr<C> _ptr_outC;
};
