hash_multiset::rend

Returns an iterator that addresses the location succeeding the last element in a reversed hash_multiset.

const_reverse_iterator rend( ) const; 
reverse_iterator rend( );

Return Value

A reverse bidirectional iterator that addresses the location succeeding the last element in a reversed hash_multiset (the location that had preceded the first element in the unreversed hash_multiset).

Remarks

rend is used with a reversed hash_multiset just as end is used with a hash_multiset.

If the return value of rend is assigned to a const_reverse_iterator, then the hash_multiset object cannot be modified. If the return value of rend is assigned to a reverse_iterator, then the hash_multiset object can be modified. The value returned by rend should not be dereferenced.

rend can be used to test to whether a reverse iterator has reached the end of its hash_multiset.

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_rend.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;
   hash_multiset <int>::reverse_iterator hms1_rIter;
   hash_multiset <int>::const_reverse_iterator hms1_crIter;

   hms1.insert( 10 );
   hms1.insert( 20 );
   hms1.insert( 30 );

   hms1_rIter = hms1.rend( );
   hms1_rIter--;
   cout << "The last element in the reversed hash_multiset is "
        << *hms1_rIter << "." << endl;

   // end can be used to terminate an iteration 
   // through a hash_multiset in a forward order
   cout << "The hash_multiset is: ";
   for ( hms1_Iter = hms1.begin( ) ; hms1_Iter != hms1.end( );
         hms1_Iter++ )
      cout << *hms1_Iter << " ";
   cout << "." << endl;

   // rend can be used to terminate an iteration 
   // throught a hash_multiset in a reverse order
   cout << "The reversed hash_multiset is: ";
   for ( hms1_rIter = hms1.rbegin( ) ; hms1_rIter != hms1.rend( );
         hms1_rIter++ )
      cout << *hms1_rIter << " ";
   cout << "." << endl;

   hms1_rIter = hms1.rend( );
   hms1_rIter--;
   hms1.erase ( *hms1_rIter );

   hms1_rIter = hms1.rend( );
   hms1_rIter--;
   cout << "After the erasure, the last element in the "
        << "reversed hash_multiset is " << *hms1_rIter << "."
        << endl;
}

The last element in the reversed hash_multiset is 10.
The hash_multiset is: 10 20 30 .
The reversed hash_multiset is: 30 20 10 .
After the erasure, the last element in the reversed hash_multiset is 20.
