hash_multiset::key_type

A type that provides a function object that can compare sort keys to determine the relative order of two elements in the hash_multiset.

typedef Key key_type;

Remarks

key_type is a synonym for the template parameter Key.

Note that both key_type and value_type are synonyms for the template parameter Key. Both types are provided for the set and multiset classes, where they are identical, for compatibility with the map and multimap classes, where they are distinct.

For more information on Key, see the Remarks section of the hash_multiset Class topic.

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 value_type for an example of how to declare and use key_type.
