hash_set::swap (STL/CLR)

交換兩個容器的內容。

    void swap(hash_set<Key>% right);

參數

• right
  要交換內容的容器。

備註

成員函式交換在 this 和 right的控制順序。 它在常數時間執行，而且不會擲回例外狀況。 您將它當做一個快速的方法交換兩個容器的內容。

範例

// cliext_hash_set_swap.cpp 
// compile with: /clr 
#include <cliext/hash_set> 
 
typedef cliext::hash_set<wchar_t> Myhash_set; 
int main() 
    { 
    Myhash_set 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 
    Myhash_set 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); 
    }
