hash_map::const_iterator

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

typedef list<typename Traits::value_type, typename Traits::allocator_type>::const_iterator const_iterator;

Remarks

A type const_iterator cannot be used to modify the value of an element.

The const_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 const_iterator cIter pointing to an element in a hash_map, use the -> operator.

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

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.
