NAME¶

std::ranges::adjacent_view::end - std::ranges::adjacent_view::end

Synopsis¶

constexpr auto end() requires (!__SimpleView<V>); (1) (since C++23)
constexpr auto end() const requires ranges::range<const V>; (2) (since C++23)

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

Let base_ be the underlying view.

1) Equivalent to:

if constexpr (ranges::common_range<V>)
return /*iterator*/<false>(__as_sentinel{}, ranges::begin(base_), ranges::end(base_));
else
return /*sentinel*/<false>(ranges::end(base_));

2) Equivalent to:

if constexpr (ranges::common_range<const V>)
return /*iterator*/<true>(__as_sentinel{}, ranges::begin(base_), ranges::end(base_));
else
return /*sentinel*/<true>(ranges::end(base_));

Parameters¶

(none)

Return value¶

An iterator to the element following the last element, if the underlying view V
models common_range. Otherwise, a sentinel which compares equal to the end iterator.

Notes¶

ranges::adjacent_view<V,N> models common_range whenever the underlying view V does.
