Question

Consider the following class:

template <typename Type>
class Wrapper
{
    public:
        Wrapper(const Type& x) : _data(x) {;}
        Wrapper<Type>& operator=(const Type& x) {_data = x; return *this;}
    protected:
        Type _data;
};

What would be the definition of the move constructor Wrapper(Type&& x) and the move assignment operator operator=(Type&& x) of this class ?

Answer 1

Wrapper(Type&& x) : _data(std::move(x)) {}
Wrapper& operator=(Type&& x) {_data = std::move(x); return *this;}
