Synopsis

#include <rw/tphdict.h>
template <class K, class T, class H, class EQ,
          class A=std::allocator<T*> >
class  RWTPtrHashMapConstIterator

Description

RWTPtrHashMapConstIterator provides a const iterator interface to the Standard Library-based RWTPtrHashMap. This iterator prohibits any changes to the underlying collection.

Iteration over an RWTPtrHashMap 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 preincrement or operator().

For both operator++ and operator(), iterating past the last element returns a value equivalent to boolean false. Once this state is reached, continued increments 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.
