Thread: copy constructor for a class with an abstract member

Hi everyone!


This question is related to how implement a copy constructor for a class that has a pointer to an abstract type. Here is an example:

Code:

class MyAbstract
{
public:    
    virtual void abstractMethod() const = 0;


};


class UseAbstract
{
public:
    UseAbstract (MyAbstract *abstract, int b)
    {
        abstract_ = abstract;
        b_ = b;
    }
    
    UseAbstract (const UseAbstract &other)
    {
        b_ = other.b_;
        //abstract_ = new ??
    }
    
private:
    MyAbstract *abstract_;
    int b_;
};

How can I implement the copy constructor for UseAbstract? I can't create an object for 'MyAbstract'.


Thanks a lot!

maybe the solutions works for you as well.
