std::ranges...view::begin(3) C++ Standard Libary std::ranges...view::begin(3) NAME std::ranges::chunk_view::begin - std::ranges::chunk_view::begin Synopsis V models only input_range constexpr __outer_iterator begin(); (1) (since C++23) V models forward_range constexpr auto begin() requires (!__simple_view<V>); (2) (since C++23) constexpr auto begin() const requires ranges::forward_range<const (3) (since C++23) V>; Returns an iterator to the first element of the chunk_view. Let base_ denote the underlying view. 1) Available only if V models input_range. Equivalent to: current_ = ranges::begin(base_); remainder_ = n_; return __outer_iterator(*this); current_, remainder_, and n_ are underlying exposition only data members of chunk_view. 2) Available if V models forward_range. Equivalent to: return itera- tor<false>(this, ranges::begin(base_));, where iterator is exposition only nested class. 3) Available if V models forward_range. Equivalent to: return itera- tor<true>(this, ranges::begin(base_));, where iterator is exposition only nested class. Parameters (none) Return value An iterator to the first element of the chunk_view, as described above. Example This section is incomplete Reason: no example See also end returns an iterator or a sentinel to the end (C++23) (public member function) ranges::begin returns an iterator to the beginning of a range (C++20) (customization point object) Category: * Todo no example http://cppreference.com 2024.06.10 std::ranges...view::begin(3)
