operator==(join_with_view::sentinel) (C++23)

 

constexpr auto end();	(1)	(since C++23)
constexpr auto end() const   requires ranges::input_range<const V> &&            ranges::forward_range<const Pattern> &&            std::is_reference_v<ranges::range_reference_t<const V>>;	(2)	(since C++23)

Returns an iterator or a sentinel that compares equal to the end iterator of the join_with_view.

Let base_ denote 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> && __SimpleView<Pattern>>{*this, ranges::end(base_)};
else  
    return /*sentinel*/<__SimpleView<V> && __SimpleView<Pattern>>{*this};

2) Equivalent to:

if constexpr (ranges::forward_range<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

An iterator or sentinel representing the end of the join_with_view, as described above.
