std::ranges...k_view::end(3) C++ Standard Libary std::ranges...k_view::end(3) NAME std::ranges::chunk_view::end - std::ranges::chunk_view::end Synopsis V models only input_range constexpr std::default_sentinel_t end() const noexcept; (1) (since C++23) V models forward_range constexpr auto end() requires (!__simple_view<V>); (2) (since C++23) constexpr auto end() const requires ranges::forward_range<const (3) (since C++23) V>; Returns an iterator or a std::default_sentinel that compares equal to the end iterator of the chunk_view. 1) Available only if V models input_range. Equivalent to: return std::default_sentinel. 2,3) Available if V models forward_range. Let base_ denote the un- derlying adapted view, n_ denote the stored chunk size, and iterator denote the nested iterator class. 2) Equivalent to: if constexpr (ranges::common_range<V> && ranges::sized_range<V>) { auto missing = (n_ - ranges::distance(base_) % n_) % n_; return iterator<false>(this, ranges::end(base_), missing); } else if constexpr (ranges::common_range<V> && !ranges::bidirec- tional_range<V>) return iterator<false>(this, ranges::end(base_)); else return std::default_sentinel; 3) Equivalent to: if constexpr (ranges::common_range<const V> && ranges::sized_range<const V>) { auto missing = (n_ - ranges::distance(base_) % n_) % n_; return iterator<true>(this, ranges::end(base_), missing); } else if constexpr (ranges::common_range<const V> && !ranges::bidirec- tional_range<const V>) return iterator<true>(this, ranges::end(base_)); else return std::default_sentinel; Parameters (none) Return value An iterator or sentinel representing the end of the chunk_view, as described above. Example This section is incomplete Reason: no example See also begin returns an iterator to the beginning (C++23) (public member function) ranges::end returns a sentinel indicating the end of a range (C++20) (customization point object) Category: * Todo no example http://cppreference.com 2024.06.10 std::ranges...k_view::end(3)
