hash_multiset::swap

Exchanges the elements of two hash_multisets.

void swap( 
   hash_multiset& _Right 
);

Parameters

• _Right
  The argument hash_multiset providing the elements to be swapped with the target hash_multiset.

Remarks

The member function invalidates no references, pointers, or iterators that designate elements in the two hash_multisets whose elements are being exchanged.

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

int main( )
{
   using namespace std;
   using namespace stdext;
   hash_multiset <int> hms1, hms2, hms3;
   hash_multiset <int>::iterator hms1_Iter;

   hms1.insert( 10 );
   hms1.insert( 20 );
   hms1.insert( 30 );
   hms2.insert( 100 );
   hms2.insert( 200 );
   hms3.insert( 300 );

   cout << "The original hash_multiset hms1 is:";
   for ( hms1_Iter = hms1.begin( ); hms1_Iter != hms1.end( );
         hms1_Iter++ )
         cout << " " << *hms1_Iter;
   cout   << "." << endl;

   // This is the member function version of swap
   hms1.swap( hms2 );

   cout << "After swapping with hms2, list hms1 is:";
   for ( hms1_Iter = hms1.begin( ); hms1_Iter != hms1.end( );
         hms1_Iter++ )
         cout << " " << *hms1_Iter;
   cout  << "." << endl;

   // This is the specialized template version of swap
   swap( hms1, hms3 );

   cout << "After swapping with hms3, list hms1 is:";
   for ( hms1_Iter = hms1.begin( ); hms1_Iter != hms1.end( );
         hms1_Iter++ )
         cout << " " << *hms1_Iter;
   cout   << "." << endl;
}

The original hash_multiset hms1 is: 10 20 30.
After swapping with hms2, list hms1 is: 200 100.
After swapping with hms3, list hms1 is: 300.
