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
#define _DEFINE_DEPRECATED_HASH_CLASSES 0
#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.
