Synopsis

#include <rw/iterator.h>
typedef RWConstIterator Iterator;  //Smalltalk typedef: deprecated.

Description

Class RWConstIterator is an abstract base class for const iterators used by the Smalltalk-like collection classes. The const iterators do not change any information in the data structure upon which they iterate.

The class contains virtual functions for positioning and resetting the iterator. They are all pure virtual functions, meaning that deriving classes must supply a definition. The descriptions below are intended to be generic -- all inheriting iterators generally follow the described pattern.

Persistence

None

Public Virtual Functions

virtual const RWCollectable*
findNext(const RWCollectable* target) = 0;

reset() = 0;
