Synopsis

// Smalltalk typedef.
typedef RWSlistCollectablesIterator LinkedListIterator;
#include <rw/slistcol.h>
RWSlistCollectables sc;
RWSlistCollectablesIterator sci(sc) ;

Description

Iterator for class RWSlistCollectables. Traverses the linked-list from the first to last item.

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Once the iterator has advanced beyond the end of the collection it is no longer valid -- continuing to use it will bring undefined results.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