Synopsis

#include <rw/hashdict.h>

RWHashDictionary hd;
RWHashDictionaryConstIterator  iter(hd);

Description

One of two iterators for class RWHashDictionary. This iterator allows sequential access to all the elements of RWHashDictionary, and, as a const iterator, does not change anything in the underlying data structure. Since RWHashDictionary is unordered, elements are not accessed in any particular order.

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Once the iterator has advanced beyond the end of the collection it is no longer valid -- continuing to use it will bring undefined results.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