void swap( unordered_multimap& 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. The past-the-end iterator is invalidated.
The Hash
and KeyEqual
objects must be Swappable
, and they are exchanged using unqualified calls to non-member swap
.
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) |
