map::const_reverse_iterator

A type that provides a bidirectional iterator that can read any const element in the map.

typedef std::reverse_iterator<const_iterator> const_reverse_iterator;

Remarks

A type const_reverse_iterator cannot modify the value of an element and is use to iterate through the map in reverse.

The const_reverse_iterator defined by 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 const_reverse_iterator crIter pointing to an element in a map, use the -> operator.

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

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