#include <ace/Containers.h>
template<class T>
class ACE_Unbounded_Queue_Iterator
{
  public:
    ACE_Unbounded_Queue_Iterator (
        ACE_Unbounded_Queue<T> &q,
        int end = 0
        );

    ACE_Unbounded_Queue<T> &queue_;
};

DESCRIPTION

This implementation of an unordered set uses a fixed array. This implementation does not allow duplicates...

Initialization method.

ACE_Unbounded_Queue_Iterator (ACE_Unbounded_Queue<T> &q, int end = 0);

Iteration methods.

int next (T *&next_item);

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

int advance (void);

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

int first (void);

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

int done (void) const;

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

void dump (void) const;

Dump the state of an object.

ACE_ALLOC_HOOK_DECLARE;

Declare the dynamic allocation hooks.
