Synopsis

#include <rw/hashtab.h>
RWHashTable h;
RWHashTableIterator it(h);

Description

Iterator for class RWHashTable, which allows sequential access to all the elements of RWHashTable. Note that because an RWHashTable is unordered, elements are not accessed in any particular order.

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Once the iterator has advanced beyond the end of the collection it is no longer valid -- continuing to use it will bring undefined results.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