multiset::swap

交换两多个集的元素。

void swap(
   multiset<Key, Compare, Allocator>& _Right
);

参数

  • _Right
    提供元素的参数多个集将交换与目标多个集。

备注

函数无效的情况成员引用,在两多个集的指定元素交换的指针或迭代器。

示例

// multiset_swap.cpp
// compile with: /EHsc
#include <set>
#include <iostream>

int main( )
{
   using namespace std;
   multiset <int> ms1, ms2, ms3;
   multiset <int>::iterator ms1_Iter;

   ms1.insert( 10 );
   ms1.insert( 20 );
   ms1.insert( 30 );
   ms2.insert( 100 );
   ms2.insert( 200 );
   ms3.insert( 300 );

   cout << "The original multiset ms1 is:";
   for ( ms1_Iter = ms1.begin( ); ms1_Iter != ms1.end( ); ms1_Iter++ )
      cout << " " << *ms1_Iter;
   cout << "." << endl;

   // This is the member function version of swap
   ms1.swap( ms2 );

   cout << "After swapping with ms2, list ms1 is:";
   for ( ms1_Iter = ms1.begin( ); ms1_Iter != ms1.end( ); ms1_Iter++ )
      cout << " " << *ms1_Iter;
   cout << "." << endl;

   // This is the specialized template version of swap
   swap( ms1, ms3 );

   cout << "After swapping with ms3, list ms1 is:";
   for ( ms1_Iter = ms1.begin( ); ms1_Iter != ms1.end( ); ms1_Iter++ )
      cout << " " << *ms1_Iter;
   cout   << "." << endl;
}
