我的编码风格包括以下习语:

class Derived : public Base
{
   public :
      typedef Base super; // note that it could be hidden in
                          // protected/private section, instead

      // Etc.
} ;

这使我能够使用"super"作为Base的别名,例如,在构造函数中:

Derived(int i, int j)
   : super(i), J(j)
{
}

或者甚至在其重写版本中从基类调用方法时:

void Derived::foo()
{
   super::foo() ;

   // ... And then, do something else
}

它甚至可以链接(我仍然可以找到它的用途):

class DerivedDerived : public Derived
{
   public :
      typedef Derived super; // note that it could be hidden in
                             // protected/private section, instead

      // Etc.
} ; …
