std::experimental::ranges::Sentinel(3) | C++ Standard Libary | std::experimental::ranges::Sentinel(3) |
NAME¶
std::experimental::ranges::Sentinel - std::experimental::ranges::Sentinel
Synopsis¶
Defined in header <experimental/ranges/iterator>
template< class S, class I >
concept bool Sentinel = (ranges TS)
Semiregular<S> && Iterator<I> &&
WeaklyEqualityComparableWith<S, I>;
The Sentinel concept specifies the relationship between an Iterator type and
a
Semiregular type whose values denote a range.
Let s and i be values of type S and I, respectively, such that [i, s) denotes
a
range. Sentinel<S, I> is satisfied only if:
* i == s is well-defined.
* If bool(i != s) then i is dereferenceable and [++i, s) denotes a range.
The domain of == can change over time. Given an iterator i and sentinel s
such that
[i, s) denotes a range and i != s, [i, s) is not required to continue to
denote a
range after incrementing any iterator equal to i (and so i == s is no longer
required to be well-defined after such an increment).
