hash_set::value_compare
Note
This API is obsolete. The alternative is unordered_set Class.
A type that provides two function objects, a binary predicate of class compare that can compare two element values of a hash_set to determine their relative order and a unary predicate that hashes the elements.
typedef key_compare value_compare;
Remarks
value_compare is a synonym for the template parameter Traits.
For more information on Traits see the hash_set 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 the example for value_comp for an example of how to declare and use value_compare.
