set::swap (STL/CLR)

交换两个容器的内容。

    void swap(set<Key>% right);

参数

• right
  要与其交换内容的容器。

备注

成员函数交换。 this 和 right之间的控件序列。它在常数时执行此操作，且不引发异常。将它用作一种快速交换两个容器的内容。

示例

// cliext_set_swap.cpp 
// compile with: /clr 
#include <cliext/set> 
 
typedef cliext::set<wchar_t> Myset; 
int main() 
    { 
    Myset c1; 
    c1.insert(L'a'); 
    c1.insert(L'b'); 
    c1.insert(L'c'); 
 
// display initial contents " a b c" 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
// construct another container with repetition of values 
    Myset c2; 
    c2.insert(L'd'); 
    c2.insert(L'e'); 
    c2.insert(L'f'); 
    for each (wchar_t elem in c2) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
// swap and redisplay 
    c1.swap(c2); 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
    for each (wchar_t elem in c2) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
    return (0); 
    }
