[edit]

class/sentinel/;		(since C++20) (exposition only*)

The return type offilter_view::end when the underlyingviewV does not modelcommon_range.

[edit]Data members

Member	Definition
`Vend_`(private)	the sentinel of the underlying`view` (exposition-only member object*)

[edit]Member functions

(constructor)	constructs a sentinel (public member function)
base	returns the underlying sentinel (public member function)

std::ranges::filter_view::sentinel::sentinel

/sentinel/()=default;	(1)	(since C++20)
constexprexplicit/sentinel/( filter_view& parent);	(2)	(since C++20)

1) Value-initializesend_ via its default member initializer (=ranges::sentinel_t<V>()).

2) Initializesend_ withranges::end(parent.base_).

std::ranges::filter_view::sentinel::base

constexprranges::sentinel_t<V> base()const;		(since C++20)

Equivalent toreturn end_;.

[edit]Non-member functions

operator==

(C++20)

compares the underlying iterator and the underlying sentinel
(function)

operator==(std::ranges::filter_view::iterator, std::ranges::filter_view::sentinel)

friendconstexprbool operator==(const/iterator/& x, const/sentinel/& y);		(since C++20)

Equivalent toreturn x.current_== y.end_;, wherecurrent_ is the underlying iterator wrapped infilter_view::iterator.

The!= operator issynthesized fromoperator==.

This function is not visible to ordinaryunqualified orqualified lookup, and can only be found byargument-dependent lookup whenstd::ranges::filter_view::sentinel is an associated class of the arguments.
