Synopsis

#include<rw/tpset.h>
RWTPtrSet<T,C,A> set;
RWTPtrSetIterator<T,C,A> itr(set);

Description

RWTPtrSetIterator provides the traditional Tools.h++ iterator interface to the Standard Library-based collections. (An STL iterator interface is provided through RWTPtrSet::iterator.)

The order of iteration over an RWTPtrSet is dependent on the comparator object supplied as applied to the values stored in the container.

The current item referenced by this iterator is undefined after construction or after a call to reset(). The iterator becomes valid after being advanced with either a preincrement or operator().

For both operator++ and operator(), iterating past the last element will return a value equivalent to boolean FALSE. Continued increments will return a value equivalent to FALSE until reset() is called.

The value type must have operator== and operator< defined. This requirement is imposed by the Standard C++ Library.
