RWDlistCollectablesIterator


RWDlistCollectablesIterator-->RWIterator

Data Type and Member Function Indexes
(exclusive of constructors and destructors)

Synopsis

#include <rw/dlistcol.h>
RWDlistCollectables d;
RWDlistCollectablesIterator it(d) ;

Description

Iterator for class RWDlistCollectables. Traverses the linked-list from the first (head) to the last (tail) item. Functions are provided for moving in either direction.

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Once the iterator has advanced beyond the end of the collection it is no longer valid -- continuing to use it will bring undefined results.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

RWDlistCollectablesIterator (RWDlistCollectables& d);
