| void swap( {{{1}}}& other ); |
(since {std}) | |
Exchanges the contents of the container with those of other. Does not invoke any move, copy, or swap operations on individual elements.
| Information on iterator invalidation is copied from here |
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). |
