NAME¶

std::ranges::transform_view::sentinel - std::ranges::transform_view::sentinel

Synopsis¶

template< bool Const > (since C++20)
class /*sentinel*/

The return type of transform_view::end when the underlying view is not a
common_range.

The type /*sentinel*/<true> is returned by the const-qualified overload. The type
/*sentinel*/<false> is returned by the non-const-qualified overload.

The name of this class template (shown here as /*sentinel*/) is unspecified.

Typical implementation holds only one data member: a sentinel obtained from
(possibly const-qualified) V.

Member types¶

Member type Definition
Parent (private) const transform_view<V, F> if Const is true, otherwise
transform_view<V, F>. The name is for exposition only
Base (private) const V if Const is true, otherwise V. The name is for exposition
only

Member functions¶

constructor constructs a sentinel
(C++20) (public member function)
base returns the underlying sentinel
(C++20) (public member function)

Non-member functions¶

operator== compares a sentinel with an iterator returned from transform_view::begin
(C++20) (function)
operator- computes the distance between a sentinel and an iterator returned from
(C++20) transform_view::begin
(function)
