std::deque::swap

STD::DEQUE::SWAP

void swap( deque& other (until C++17)
void swap( deque& other ) noexcept(/* see below */(since C++17)

将容器的内容与other不对单个元素调用任何移动、复制或交换操作。

所有迭代器和引用仍然有效。过去的迭代器无效.

If std::allocator_traits::propagate_on_container_swap::value is true, then the allocators are exchanged using an unqualified call to non-member swap. Otherwise, they are not swapped (and if get_allocator() != other.get_allocator(), the behavior is undefined).(since C++11)

参数

other-container to exchange the contents with

返回值

%280%29

例外

(none).(until C++17)
noexcept specification: noexcept(std::allocator_traits<Allocator>::is_always_equal::value)(since C++17)

复杂性

常量。
