Give access to encapsulated container

Question

class X {
  public:
    typedef std::list Container;

    // (1)
    const Container& GetElements() const;

    // (2)
    Container::iterator Element         


        

Answer 1

Off course, the simplest is this :

class X {
  public:
    typedef std::list Container;

    Container m_container;
};

but that makes your class X obsolete.

Other then that, if you really like your class, then add next methods :

Container::const_iterator ElementBegin() const;
Container::const_iterator ElementEnd() const;
int size() const;
