NAME¶

std::ranges::join_view::end - std::ranges::join_view::end

Synopsis¶

constexpr auto end(); (1) (since
C++20)
constexpr auto end() const

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

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.
