std::forward_list<T,Allocator>::swap (3) - Linux Man Pages

std::forward_list<T,Allocator>::swap: std::forward_list<T,Allocator>::swap

NAME

std::forward_list<T,Allocator>::swap - std::forward_list<T,Allocator>::swap

Synopsis


void swap( forward_list& other ); (since C++11)
                                                             (until C++17)
void swap( forward_list& other ) noexcept(/* see below */); (since C++17)


Exchanges the contents of the container with those of other. Does not invoke any move, copy, or swap operations on individual elements.
All iterators and references remain valid. It is unspecified whether an iterator holding the past-the-end value in this container will refer to this or the other container after the operation.


If std::allocator_traits<allocator_type>::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)

Parameters


other - container to exchange the contents with

Return value


(none)

Exceptions


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

Complexity


Constant.
