# ACE\_Iterator(3)

Defines the iterator interface.

## NAME

ACE\_Iterator -  Defines the iterator interface.

## SYNOPSIS

```
#include <ace/Map_T.h>
template<class T>
class ACE_Iterator
{
  public:
    typedef T value_type;
    typedef ACE_Iterator_Impl<T> implementation;
    ACE_Iterator (ACE_Iterator_Impl<T> *impl);
    ACE_Iterator (const ACE_Iterator<T> &rhs);
    ~ACE_Iterator (void);
    ACE_Iterator<T> &operator= (const ACE_Iterator<T> &rhs);
    int operator== (const ACE_Iterator<T> &rhs) const;
    int operator!= (const ACE_Iterator<T> &rhs) const;
    T operator *() const;
    ACE_Iterator<T> &operator++ (void);
    ACE_Iterator<T> operator++ (int);
    ACE_Iterator<T> &operator-- (void);
    ACE_Iterator<T> operator-- (int);
    ACE_Iterator_Impl<T> &impl (void);
  protected:
    ACE_Iterator_Impl<T> *implementation_;
};
```
