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
.

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 ]
