std::experimental::ranges::InputIterator - cppreference.com (original) (raw)

| | | | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | ----------- | | template< class I > concept bool InputIterator = Iterator<I> && Readable<I> && requires { typename ranges::iterator_category_t<I>; } && DerivedFrom<ranges::iterator_category_t<I>, ranges::input_iterator_tag>; | | (ranges TS) |

The InputIterator concept is a refinement of Iterator, adding the requirement that the referenced values can be read (via Readable) and the requirement that the iterator category tag be present.

[edit] Notes

Unlike the input iterator requirements in the C++ standard, InputIterator in the Ranges TS does not require EqualityComparable.
