std::ranges::join_view<V>::end

< cpp‎ | ranges‎ | join view
constexpr auto end();
 (1) (since C++20)
constexpr auto end() const

    requires ranges::input_range<const V> &&

             std::is_reference_v<ranges::range_reference_t<const V>>;
 (2) (since C++20)

Returns a sentinel or an iterator representing the end of the join_view.

Let base_ be the underlying view:

1) Equivalent to 
if constexpr (ranges::forward_range<V> &&
              std::is_reference_v<ranges::range_reference_t<V>> &&
              ranges::forward_range<ranges::range_reference_t<V>> &&
              ranges::common_range<V> &&
              ranges::common_range<ranges::range_reference_t<V>>)
    return /*iterator*/<__SimpleView<V>>{*this, ranges::end(base_)};
else  
    return /*sentinel*/<__SimpleView<V>>{*this};
2) Equivalent to 
if constexpr (ranges::forward_range<const V> &&
              std::is_reference_v<ranges::range_reference_t<const V>> &&
              ranges::forward_range<ranges::range_reference_t<const V>> &&
              ranges::common_range<const V> &&
              ranges::common_range<ranges::range_reference_t<const V>>)
    return /*iterator*/<true>{*this, ranges::end(base_)};
else
    return /*sentinel*/<true>{*this};

Parameters

(none)

Return value

1) sentinel which compares equal to the end iterator.
2) iterator to the element following the last element.
