std::ranges::split_view<V,Pattern>::sentinel

< cpp‎ | ranges‎ | split view
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.
