RWOrderedIterator()

#include <rw/ordcltn.h>
RWOrdered a ;
RWOrderedIterator iter(a);

Iterator for class RWOrdered. Traverses the collection from the first to the last item. Like all Rogue Wave iterators, the "current item" is undefined immediately after construction -- you must define it by using operator() or some other (valid) operation.

Once the iterator has advanced beyond the end of the collection it is no longer valid -- continuing to use it will bring undefined results.

None

RWOrderedIterator(const RWOrdered& a);

Construct an RWOrderedIterator from an RWOrdered. Immediately after construction the position of the iterator is undefined.

virtual RWCollectable*
operator()(); 

Redefined from class RWIterator. Advances the iterator to the next item and returns it. Returns rwnil when the end of the collection is reached.

virtual RWCollectable*
findNext(const RWCollectable*);

Redefined from class RWIterator. Moves iterator to the next item which isEqual to the item pointed to by target and returns it. If no item is found, returns nil and the position of the iterator will be undefined.

virtual RWCollectable*
key() const;

Redefined from class RWIterator. Returns the item at the current iterator position.

virtual void
reset();

Redefined from class RWIterator. Resets the iterator to its starting state.
