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_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);
}
