RWOrderedIterator(3C++) RWOrderedIterator(3C++)
NameRWOrderedIterator - Rogue Wave library class
Synopsis
#include <rw/ordcltn.h>
RWOrdered a ;
RWOrderedIteratoriter(a);
Description
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advanced beyond the end of the collection it is no longer valid --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.
Persistence
None
Public Constructors
RWOrderedIterator(const RWOrdered& a);
Construct an RWOrderedIterator from an RWOrdered. Immediately after
construction the position of the iterator is undefined.
Public Member Operator
virtual RWCollectable*
operator()();
Redefined from class RWIterator. Advances the iterator to the next item
and returns it. Returns nil when the end of the collection is reached.
Public Member Functions
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;

RWOrderedIterator(3C++) RWOrderedIterator(3C++)
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.
