NAME¶

std::ranges::slide_view::end - std::ranges::slide_view::end

Synopsis¶

constexpr auto end()
requires (!(__simple_view<V> && __slide_caches_nothing<const (1) (since C++23)
V>));
constexpr auto end() const (2) (since C++23)
requires __slide_caches_nothing<const V>;

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

1) Let base_ and n_ be the underlying data members. Equivalent to:
* If V models __slide_caches_nothing, return iterator<false>(ranges::begin(base_)
+ ranges::range_difference_t<V>(size()), n_);.
* Otherwise, if V models __slide_caches_last, return
iterator<false>(ranges::prev(ranges::end(base_), n_ - 1, ranges::begin(base_)),
n_);.
* Otherwise, if V models common_range, return iterator<false>(ranges::end(base_),
ranges::end(base_), n_);.
* Otherwise, return sentinel(ranges::end(base_));.
If V models __slide_caches_last, this function caches the result within the
slide_view::cached_end_ for use on subsequent calls. This is necessary to provide
the amortized constant-time complexity required by the range.
2) Equivalent to begin() + ranges::range_difference_t<const V>(size()).

Parameters¶

(none)

Return value¶

A sentinel or an iterator representing the end of the slide_view.

Example¶

// Run this code

#include <iostream>
#include <ranges>

int main()
{
static constexpr auto source = {'A', 'B', 'C', 'D'};

for (const auto subrange: source | std::views::slide(3))
{
std::cout << "[ ";
for (auto it = subrange.begin(); it != subrange.end(); ++it)
std::cout << *it << ' ';
std::cout << "]\n";
}
}

Output:¶

[ A B C ]
[ B C D ]
