Detailed 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

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Once the iterator has advanced beyond the end of the collection, it is no longer valid.

Synopsis

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

Persistence

None

Constructor & Destructor Documentation

RWSetConstIterator::RWSetConstIterator ( const RWSet &  h )

inline

Constructs a const iterator for an RWSet. After construction, the position of the iterator is undefined.

RWSetConstIterator::RWSetConstIterator ( const RWSetIterator &  it )

inline

Constructs a const iterator from an iterator. After construction, the position of the const iterator is undefined.

Member Function Documentation

void RWSetConstIterator::reset ( )

inlinevirtual

Resets the iterator to the state it had immediately after construction.
