std::ranges...view::begin(3) C++ Standard Libary std::ranges...view::begin(3) NAME std::ranges::join_with_view::begin - std::ranges::join_with_view::begin Synopsis constexpr auto begin(); (1) (since C++23) constexpr auto begin() const requires ranges::input_range<const V> && (2) (since ranges::forward_range<const Pattern> && C++23) std::is_reference_v<ranges::range_reference_t<const V>>; Returns an iterator to the first element of the join_with_view. Let base_ denote the underlying view: 1) Equivalent to return /*iterator*/<true>{*this, ranges::begin(base_)}; if V and Pattern each model __SimpleView and ranges::range_reference_t<V> is a reference type; otherwise equivalent to return /*iterator*/<false>{*this, ranges::begin(base_)};. 2) Equivalent to return /*iterator*/<true>{*this, ranges::be- gin(base_)};. Parameters (none) Return value An iterator to the first element of the join_with_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)
