hash_multiset::key_compare

A type that provides two function objects, a binary predicate of class compare that can compare two element values of a hash_multiset to determine their relative order and a unary predicate that hashes the elements.

typedef Traits key_compare;

Remarks

key_compare is a synonym for the template parameter Traits.

For more information on Traits see the hash_multiset Class topic.

Note that both key_compare and value_compare are synonyms for the template parameter Traits. Both types are provided for the hash_set and hash_multiset classes, where they are identical, for compatibility with the hash_map and hash_multimap classes, where they are distinct.

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 key_comp for an example of how to declare and use key_compare.
