void swap( set& other );

Exchanges the contents of the container with those of other.

All iterators and references remain valid. The past-the-end iterator is invalidated.

The behavior is undefined if get_allocator() != other.get_allocator() and std::allocator_traits<allocator_type>::propagate_on_container_swap::value != true.

Parameters

other

-

container to exchange the contents with

Return value

(none)

Exceptions

noexcept specification:  

noexcept

  (since C++11)

Complexity

Constant
