Synopsis

template <class K, class T, class C,
          class A=std::allocator<T*> >
class  RWTPtrMultiMapConstIterator

Description

RWTPtrMultiMapConstIterator provides a const iterator interface to the Standard Library-based RWTPtrMultiMap collection. A const iterator prohibits changes to the collection it iteratres through.

The order of iteration over an RWTPtrMultiMap is dependent on the comparator object of the container 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.
