RWOrderedConstIterator()

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

One of two iterators for class RWOrdered. Traverses the collection from the first to the last item. As a const iterator, this iterator does not change anything in the underlying data structure.

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Once the iterator has advanced beyond the end of the collection it is no longer valid -- continuing to use it will bring undefined results.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

RWOrderedConstIterator(const RWOrdered& a);

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

virtual const RWCollectable*
operator()(); 

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

virtual const RWCollectable*
findNext(const RWCollectable*);

Redefined from class RWConstIterator. 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 is undefined.

virtual const RWCollectable*
key() const;

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

virtual void
reset();

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