#include <ace/Map_T.h>
template<class T, class IMPLEMENTATION, class ENTRY>
class ACE_Map_Impl_Reverse_Iterator_Adapter :
  public ACE_Reverse_Iterator_Impl<T>
{
  public:
    typedef IMPLEMENTATION implementation;
    ACE_Map_Impl_Reverse_Iterator_Adapter (
        const IMPLEMENTATION &impl
        );
    virtual ~ACE_Map_Impl_Reverse_Iterator_Adapter (void);
    virtual ACE_Reverse_Iterator_Impl<T> *clone (void) const;
    virtual int compare (
        const ACE_Reverse_Iterator_Impl<T> &rhs
        ) const;
    virtual T dereference (void) const;
    virtual void plus_plus (void);
    virtual void minus_minus (void);
    IMPLEMENTATION &impl (void);
  protected:
    IMPLEMENTATION implementation_;
};
```
