From cppreference.com
< cpp | ranges | filter view
| class /*sentinel*/; |
(since C++20) (exposition only*) |
|
The return type of filter_view::end when the underlying view type (V) does not model common_range.
Data members

end_ (private)
|
The sentinel of the underlying view.(exposition-only member object*) |
Member functions
| constructs a sentinel (public member function) | |
| returns the underlying sentinel (public member function) |
std::ranges::filter_view::sentinel::sentinel
| /*sentinel*/() = default; |
(1) | (since C++20) |
| constexpr explicit /*sentinel*/( filter_view& parent ); |
(2) | (since C++20) |
std::ranges::filter_view::sentinel::base
| constexpr ranges::sentinel_t<V> base() const; |
(since C++20) | |
Equivalent to return end_;.
Non-member functions
| (C++20) |
compares the underlying iterator and the underlying sentinel (function) |
operator==(std::ranges::filter_view::iterator, std::ranges::filter_view::sentinel)
| friend constexpr bool operator==( const /*iterator*/& x, const /*sentinel*/& y ); |
(since C++20) | |
Equivalent to return x.current_ == y.end_;, where current_ is the underlying iterator wrapped in filter_view::iterator.
The != operator is synthesized from operator==.
This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::ranges::filter_view::sentinel is an associated class of the arguments.
