NAME¶
std::ranges::join_with_view::end - std::ranges::join_with_view::end
Synopsis¶
constexpr auto end(); (1) (since
C++23)
constexpr auto end() 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 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.
