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*/</*simple-view*/<V>>{*this, ranges::end(base_)};
else
    return /*sentinel*/</*simple-view*/<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.
