共用方式為


hash_multimap::swap

注意事項注意事項

這個 API 已經過時。這個選項是 unordered_multimap Class

交換兩 hash_multimaps 的項目。

void swap(
   hash_multimap& _Right
);

參數

  • _Right
    項目要切換與 hash_multimap 的 hash_multimap 提供項目會交換或 hash_multimap。

備註

成員函式不使兩 hash_multimaps 的指定項目已交換參考、指標或 Iterator。

在 Visual C++ .NET Pocket PC, <hash_map><hash_set> 標頭檔 (Header File) 的成員不在 std 命名空間,,而是移至 stdext 命名空間。 如需詳細資訊,請參閱 stdext 命名空間

範例

// hash_multimap_swap.cpp
// compile with: /EHsc
#include <hash_map>
#include <iostream>

int main( )
{
   using namespace std;
   using namespace stdext;
   hash_multimap <int, int> hm1, hm2, hm3;
   hash_multimap <int, int>::iterator hm1_Iter;
   typedef pair <int, int> Int_Pair;

   hm1.insert ( Int_Pair ( 1, 10 ) );
   hm1.insert ( Int_Pair ( 2, 20 ) );
   hm1.insert ( Int_Pair ( 3, 30 ) );
   hm2.insert ( Int_Pair ( 10, 100 ) );
   hm2.insert ( Int_Pair ( 20, 200 ) );
   hm3.insert ( Int_Pair ( 30, 300 ) );

   cout << "The original hash_multimap hm1 is:";
   for ( hm1_Iter = hm1.begin( ); hm1_Iter != hm1.end( ); hm1_Iter++ )
      cout << " " << hm1_Iter -> second;
   cout   << "." << endl;

   // This is the member function version of swap
   hm1.swap( hm2 );

   cout << "After swapping with hm2, hash_multimap hm1 is:";
   for ( hm1_Iter = hm1.begin( ); hm1_Iter != hm1.end( ); hm1_Iter++ )
      cout << " " << hm1_Iter -> second;
   cout  << "." << endl;

   // This is the specialized template version of swap
   swap( hm1, hm3 );

   cout << "After swapping with hm3, hash_multimap hm1 is:";
   for ( hm1_Iter = hm1.begin( ); hm1_Iter != hm1.end( ); hm1_Iter++ )
      cout << " " << hm1_Iter -> second;
   cout   << "." << endl;
}
