multimap::reverse_iterator

A type that provides a bidirectional iterator that can read or modify an element in a reversed multimap.

typedef std::reverse_iterator<iterator> reverse_iterator;

Remarks

A type reverse_iterator is use to iterate through the multimap in reverse.

The reverse_iterator defined by multimap points to objects of value_type, which are of type pair*<const Key, Type>*. The value of the key is available through the first member pair and the value of the mapped element is available through the second member of the pair.

To dereference a reverse_iterator rIter pointing to an element in a multimap, use the -> operator.

To access the value of the key for the element, use rIter -> first, which is equivalent to (*rIter).first. To access the value of the mapped datum for the element, use rIter -> second, which is equivalent to (*rIter).first.

Example

See the example for rbegin for an example of how to declare and use reverse_iterator.
