< cpp | ranges | lazy split view
| constexpr auto end() requires ranges::forward_range<V> && ranges::common_range<V>; |
(1) | (since C++20) |
| constexpr auto end() const; |
(2) | (since C++20) |
Returns an iterator or sometimes a sentinel representing the end of the view. Let base_ be the underlying view.
1) Returns an iterator. Equivalent to:
return /*outer_iterator*/</*simple_view*/<V>>{*this, ranges::end(base_)};.
2) Returns an
outer_iterator or a std::default_sentinel.
Equivalent to:
if constexpr (ranges::forward_range<V> && ranges::forward_range<const V> && ranges::common_range<const V>) return /*outer_iterator*/<true>{*this, ranges::end(base_)}; else return std::default_sentinel;
Return value
An outer_iterator or a std::default_sentinel representing the end of the view.
Example
Run this code
#include <iostream> #include <ranges> #include <string_view> int main() { constexpr std::string_view keywords{"false float for friend"}; std::ranges::lazy_split_view kw{keywords, ' '}; const auto count = std::ranges::distance(kw.begin(), kw.end()); std::cout << "Words count: " << count << '\n'; }
Output:
Words count: 4
