Detailed Description

template<class T>
class ACE_Unbounded_Queue_Iterator< T >

Implement an iterator over an unbounded queue.


Constructor & Destructor Documentation

template<class T >
ACE_Unbounded_Queue_Iterator< T >::ACE_Unbounded_Queue_Iterator ( ACE_Unbounded_Queue< T > &  q,
int  end = 0 
) [inline]

Member Function Documentation

template<class T >
int ACE_Unbounded_Queue_Iterator< T >::advance ( void   )  [inline]

Move forward by one element in the set. Returns 0 when all the items in the queue have been seen, else 1.

template<class T >
int ACE_Unbounded_Queue_Iterator< T >::done ( void   )  const [inline]

Returns 1 when all items have been seen, else 0.

template<class T >
void ACE_Unbounded_Queue_Iterator< T >::dump ( void   )  const [inline]

Dump the state of an object.

template<class T >
int ACE_Unbounded_Queue_Iterator< T >::first ( void   )  [inline]

Move to the first element in the queue. Returns 0 if the queue is empty, else 1.

template<class T >
int ACE_Unbounded_Queue_Iterator< T >::next ( T *&  next_item  )  [inline]

Pass back the next_item that hasn't been seen in the queue. Returns 0 when all items have been seen, else 1.


Member Data Documentation

Declare the dynamic allocation hooks.

template<class T >
ACE_Node<T>* ACE_Unbounded_Queue_Iterator< T >::current_ [private]

Pointer to the current node in the iteration.

template<class T >
ACE_Unbounded_Queue<T>& ACE_Unbounded_Queue_Iterator< T >::queue_ [private]

Pointer to the queue we're iterating over.
