Synopsis

#include<rw/tphset.h>
RWTPtrHashSet<T,H,EQ,A>   m;
RWTPtrHashSet<T,H,EQ,A>   itr(m); 

Description

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

Iteration over an RWTPtrHashSet is pseudorandom and dependent on the capacity of the underlying hash table and the hash function being used.

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 pre-increment or an 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== defined. This requirement is imposed by the Standard C++ Library.
