< cpp | ranges | slide view

| constexpr auto end() const requires /*slide-caches-nothing*/<const V>; |
(2) | (since C++23) |
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 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 ]
