hash_multiset::value_type

A type that describes an object stored as an element as a hash_multiset in its capacity as a value.

typedef Key value_type;

Remark

value_type is a synonym for the template parameter Key.

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

Note that both key_type and value_type are synonyms for the template parameter Key. Both types are provided for the classes hash_set and hash_multiset, where they are identical, for compatibility with the classes hash_map and hash_multimap, 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

// hash_multiset_value_type.cpp
// compile with: /EHsc
#include <hash_set>
#include <iostream>

int main( )
{
   using namespace std;
   using namespace stdext;
   hash_multiset <int> hms1;
   hash_multiset <int>::iterator hms1_Iter;

   // Declare value_type
   hash_multiset <int> :: value_type hmsvt_Int; 

   hmsvt_Int = 10;   // Initialize value_type

   // Declare key_type
   hash_multiset <int> :: key_type hmskt_Int;
   hmskt_Int = 20;             // Initialize key_type

   hms1.insert( hmsvt_Int );         // Insert value into s1
   hms1.insert( hmskt_Int );         // Insert key into s1

   // A hash_multiset accepts key_types or value_types as elements
   cout << "The hash_multiset has elements:";
   for ( hms1_Iter = hms1.begin() ; hms1_Iter != hms1.end( );
         hms1_Iter++)
      cout << " " << *hms1_Iter;
      cout << "." << endl;
}

The hash_multiset has elements: 10 20.
