(4) (since C++20)

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_)};.


[edit] Parameters


[edit] Return value

1,3) sentinel which compares equal to the end iterator
2,4) iterator to the element following the last element

[edit] 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.
