Hi,

I have a problem with template and wondering is there a possible way to achieve what I wanted to do. Here is my question.

template <typename T>
class A
{
public:

    typedef T*              pointer;
    typedef const pointer   const_pointer;

    A()
    {}

    template <typename D>
    A(const D& d)
    {
        // how can I store the D type 
        // so I can refer it later on
        // outside of this function
    }
};
