## Public Methods

| Contructor. If head != 0, the iterator constructed is positioned at the head of the map, it is positioned at the end otherwise. More...
int | next (ACE_Map_Entry< EXT_ID, INT_ID > *&next_entry) const

## Detailed Description

### template<class EXT_ID, class INT_ID, class ACE_LOCK>
class ACE_Map_Iterator_Base< EXT_ID, INT_ID, ACE_LOCK >

Iterator for the ACE_Map_Manager.

This class factors out common code from its templatized subclasses.

## Constructor & Destructor Documentation
