map::swap (STL/CLR)

交換兩個容器的內容。

    void swap(map<Key, Mapped>% right);

參數

• right
  要交換內容的容器。

備註

成員函式會交換受控制的序列之間this和right。 它會固定的時間，就會擲回任何例外狀況。 您可以用它做為交換兩個容器的內容的快速方法。

範例

// cliext_map_swap.cpp 
// compile with: /clr 
#include <cliext/map> 
 
typedef cliext::map<wchar_t, int> Mymap; 
int main() 
    { 
    Mymap c1; 
    c1.insert(Mymap::make_value(L'a', 1)); 
    c1.insert(Mymap::make_value(L'b', 2)); 
    c1.insert(Mymap::make_value(L'c', 3)); 
 
// display contents " [a 1] [b 2] [c 3]" 
    for each (Mymap::value_type elem in c1) 
        System::Console::Write(" [{0} {1}]", elem->first, elem->second); 
    System::Console::WriteLine(); 
 
// construct another container with repetition of values 
    Mymap c2; 
    c2.insert(Mymap::make_value(L'd', 4)); 
    c2.insert(Mymap::make_value(L'e', 5)); 
    c2.insert(Mymap::make_value(L'f', 6)); 
    for each (Mymap::value_type elem in c2) 
        System::Console::Write(" [{0} {1}]", elem->first, elem->second); 
    System::Console::WriteLine(); 
 
// swap and redisplay 
    c1.swap(c2); 
    for each (Mymap::value_type elem in c1) 
        System::Console::Write(" [{0} {1}]", elem->first, elem->second); 
    System::Console::WriteLine(); 
 
    for each (Mymap::value_type elem in c2) 
        System::Console::Write(" [{0} {1}]", elem->first, elem->second); 
    System::Console::WriteLine(); 
    return (0); 
    }
