hash_map::reverse_iterator
A type that provides a bidirectional iterator that can read or modify an element in a reversed hash_map.
typedef list<typename Traits::value_type, typename Traits::allocator_type>::reverse_iterator reverse_iterator;
Remarks
A type reverse_iterator cannot modify the value of an element and is use to iterate through the hash_map in reverse.
The reverse_iterator defined by hash_map points to elements that are objects of value_type, that is of type pair<const Key, Type>, whose first member is the key to the element and whose second member is the mapped datum held by the element.
To dereference a reverse_iterator rIter pointing to an element in a hash_map, 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.
In Visual C++ .NET 2003, members of the <hash_map> and <hash_set> header files are no longer in the std namespace, but rather have been moved into the stdext namespace. See The stdext Namespace for more information.
Example
See example for rbegin for an example of how to declare and use reverse_iterator.
