Move list element to the end in STL

问题

I have already the list pointer of CDrawObject*

std::list<CDrawObject*> elements;

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?

回答1:

Use the list method splice()

void list::splice ( iterator position, list<T,Allocator>& x, iterator i );

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

Thus to move it to the end put

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

(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)

回答2:

A std::list is a doubly-linked list, which means you do not have random access to element n. You have to can remove the element, and then use push_back.

回答3:

Remove it then append it to your list.
