hash_multiset::clear

  • Artigo

Note

This API is obsolete. The alternative is unordered_multiset Class.

Erases all the elements of a hash_multiset.

void clear( );

Remarks

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

int main( )
{
   using namespace std;
   using namespace stdext;
   hash_multiset <int> hms1;
   
   hms1.insert( 1 );
   hms1.insert( 2 );

   cout << "The size of the hash_multiset is initially " << hms1.size( )
        << "." << endl;

   hms1.clear( );
   cout << "The size of the hash_multiset after clearing is " 
        << hms1.size( ) << "." << endl;
}

The size of the hash_multiset is initially 2.
The size of the hash_multiset after clearing is 0.

Requirements

Header: <hash_set>

Namespace: stdext
