template<bool Const> class /*sentinel*/; // exposition only | (since C++20) |
The return type of take_while_view::end.
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 two data members: a sentinel that represents the end of the underlying view, and a pointer to the predicate.
| Member type | Definition |
|---|---|
Base(private) | const V if Const is true, otherwise V. The name is for exposition only |
|
(C++20) | constructs a sentinel (public member function) |
|
(C++20) | returns the underlying sentinel (public member function) |
|
(C++20) | compares a sentinel with an iterator returned from take_while_view::begin (function) |
