std::ranges::transform_view::end(3) | C++ Standard Libary | std::ranges::transform_view::end(3) |
NAME¶
std::ranges::transform_view::end - std::ranges::transform_view::end
Synopsis¶
constexpr /*sentinel*/<false> end(); (1) (since
C++20)
constexpr /*iterator*/<false> end() requires (2) (since
C++20)
ranges::common_range<V>;
constexpr /*sentinel*/<true> end() const
requires ranges::range<const V> && (3) (since
C++20)
std::regular_invocable<const F&, ranges::range_reference_t<const
V>>;
constexpr /*iterator*/<true> end() const
requires ranges::common_range<const V> && (4) (since
C++20)
std::regular_invocable<const F&, ranges::range_reference_t<const
V>>;
Returns a sentinel or an iterator representing the end of the
transform_view.
Let base_ be the underlying view:
1) Equivalent to return /*sentinel*/<false>{ranges::end(base_)};.
2) Equivalent to return /*iterator*/<false>{*this,
ranges::end(base_)};.
3) Equivalent to return /*sentinel*/<true>{ranges::end(base_)};.
4) Equivalent to return /*iterator*/<true>{*this,
ranges::end(base_)};.
Parameters¶
(none)
Return value¶
1,3) sentinel which compares equal to the end iterator
2,4) iterator to the element following the last element
Notes¶
end() returns an iterator if and only if the underlying view is a
common_range:
transform_view<V,F> models common_range whenever V does.
