std::ranges...m_view::end(3) C++ Standard Libary std::ranges...m_view::end(3) NAME std::ranges::transform_view::end - std::ranges::transform_view::end Synopsis constexpr /*sentinel*/<false> end(); (1) (since C++20) constexpr /*iterator*/<false> end() requires (2) (since C++20) ranges::common_range<V>; constexpr /*sentinel*/<true> end() const requires ranges::range<const V> && (3) (since C++20) std::regular_invocable<const F&, ranges::range_reference_t<const V>>; constexpr /*iterator*/<true> end() const requires ranges::common_range<const V> && (4) (since C++20) std::regular_invocable<const F&, ranges::range_reference_t<const V>>; Returns a sentinel or an iterator representing the end of the trans- form_view. Let base_ be the underlying view: 1) Equivalent to return /*sentinel*/<false>{ranges::end(base_)};. 2) Equivalent to return /*iterator*/<false>{*this, ranges::end(base_)};. 3) Equivalent to return /*sentinel*/<true>{ranges::end(base_)};. 4) Equivalent to return /*iterator*/<true>{*this, ranges::end(base_)};. Parameters (none) Return value 1,3) sentinel which compares equal to the end iterator 2,4) iterator to the element following the last element Notes end() returns an iterator if and only if the underlying view is a common_range: transform_view<V,F> models common_range whenever V does. Example This section is incomplete Reason: no example See also begin returns an iterator to the beginning (C++20) (public member function) ranges::end returns a sentinel indicating the end of a range (C++20) (customization point object) http://cppreference.com 2022.07.31 std::ranges...m_view::end(3)
