Deduction guides

 

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

The return type of split_view::end when the underlying view type (V) does not models common_range.

Data members

Typical implementations of sentinel hold only one non-static data member:

• end_ (exposition only*) - An object of type ranges::sentinel_t<V> that is the sentinel of the underlying view.

Member functions

(constructor) (C++20)

constructs a sentinel (public member function)

std::ranges::split_view::sentinel::sentinel

/*sentinel*/() = default;	(1)	(since C++20)
constexpr explicit /*sentinel*/( ranges::split_view& parent );	(2)	(since C++20)

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

2) Initializes end_ with ranges::end(parent.base_).

Non-member functions

operator== (C++20)

compares the underlying iterator and the underlying sentinel (function)

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

friend constexpr bool operator==( const /*iterator*/& x,                                   const /*sentinel*/& y );		(since C++20)

Equivalent to return x.cur_ == y.end_ and !x.trailing_empty_;.

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::split_view::sentinel is an associated class of the arguments.
