queue::swap

 

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

Exchanges the contents of the container adaptor with those of other. Effectively calls using std::swap; swap(c, other.c);

Parameters

other

-

container adaptor to exchange the contents with

Return value

(none)

Exceptions

In the noexcept expressions below, the identifier swap is looked up in the same manner as the C++17 std::is_nothrow_swappable trait. noexcept specification:   noexcept(noexcept(swap(c, other.c)))	(until C++17)
noexcept specification:   noexcept(std::is_nothrow_swappable<Container>::value)	(since C++17)

Complexity

Same as underlying container (typically constant)
