在 STL 中将列表元素移动到末尾

2022-01-07 00:00:00 list c++ stl

我已经有了CDrawObject*的列表指针

I have already the list pointer of CDrawObject*

std::list<CDrawObject*> elements;

如何将某些元素移动到列表的末尾.我看到 STL Algorithms Reference 但我没有找到这个操作.我该怎么做?

How I can move some element to the end of list. I see STL Algorithms Reference but i don't find this operations. How i can do it?

推荐答案

使用列表方法 splice()

Use the list method splice()

void list::splice ( iterator position, list& x, iterator i );

将迭代器 i 从列表 x 移动到当前列表的位置位置"

Move iterator i from list x into current list at position "position"

从而把它移到最后放

x.splice( x.end(), x, iter );

(它们可以是同一个列表，也可以是不同的列表，只要从中移动项的列表具有相同的类型，T 和 Allocator)

(they can both be the same list or different lists as long as the list from which the item is moved has the same type, both T and Allocator)
