Synopsis

#include <rw/tpmap.h>
template <class K, class T, class C,
          class A=std::allocator<T*> >
class  RWTPtrMapConstIterator

Description

RWTPrtMapIterator provides a const iterator interface to the Standard Library-based RWTPtrMap collection. As a const iterator, it prohibits any change to the collection upon which it iterates.

The order of iteration over an RWTPtrMap is dependent on the comparator object supplied as applied to the key values of the stored associations.

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 returns a value equivalent to boolean false. Continued increments 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.
