std::array<T,N>::swap (3) - Linux Man Pages

std::array<T,N>::swap: std::array<T,N>::swap

NAME

std::array<T,N>::swap - std::array<T,N>::swap

Synopsis


void swap( array& other ) noexcept(/* see below */); (since C++11)
                                                                (until C++20)
constexpr void swap( array& other ) noexcept(/* see below */); (since C++20)


Exchanges the contents of the container with those of other. Does not cause iterators and references to associate with the other container.

Parameters


other - container to exchange the contents with

Return value


(none)

Exceptions


noexcept specification:
noexcept(noexcept(swap(std::declval<T&>(), std::declval<T&>()))) (until C++17)
In the expression above, the identifier swap is looked up in the same manner as the one used by the C++17 std::is_nothrow_swappable trait.
noexcept specification: (since C++17)
noexcept(std::is_nothrow_swappable_v<T>)


For zero-sized arrays,
noexcept specification:
noexcept

Complexity


Linear in size of the container.
