Right design pattern to deal with polymorphic collections of objects

Question

Suppose I have the following classes:

class BaseObject {
    public:
        virtual int getSomeCommonProperty();
};

class Object1: public BaseObject {
    publ         


        

Answer 1

I think you should go for option 1 but use a static cast instead. After all the derived collection knows the type of the member variable for sure.

This answer explains it very well.
