Synopsis

#include <rw/rwset.h>
RWSet h;
RWSetConstIterator it(h);

Description

One of two iterators for class RWSet. This const iterator allows sequential access to all the elements of RWSet and prohibits any changes to the contents of the data structure. Note that because an RWSet is unordered, elements are not accessed in any particular order.

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Once the iterator has advanced beyond the end of the collection it is no longer valid.

Persistence

None
