9 Iterators library [iterators]

9.7 Iterator adaptors [iterators.predef]

9.7.1 Reverse iterators [iterators.reverse]

9.7.1.2 reverse_iterator operations [reverse.iter.ops]

9.7.1.2.1 reverse_iterator constructor [reverse.iter.cons]

constexpr reverse_iterator();

1

Effects: Value-initializes current. Iterator operations applied to the resulting iterator have defined behavior if and only if the corresponding operations are defined on a value-initialized iterator of type I.

explicit constexpr reverse_iterator(I x);

2

Effects: Initializes current with x.

constexpr reverse_iterator(const reverse_iterator<ConvertibleTo<I>>& i);

3

Effects: Initializes current with i.current.
