NAME¶

std::experimental::ranges::prev - std::experimental::ranges::prev

Synopsis¶

Defined in header <experimental/ranges/iterator>
namespace {
(ranges TS)
constexpr /* unspecified */ prev = /* unspecified */; (customization point
object)
}
Call signature
template< Iterator I > (1)
constexpr I prev( I i );
template< Iterator I > (2)
constexpr I prev( I i, ranges::difference_type_t<I> n );
template< Iterator I >
constexpr I prev( I i, ranges::difference_type_t<I> n, I (3)
bound );

Decrements the iterator i n times, or until bound is reached, whichever comes first,
and returns the decremented iterator.

1) Equivalent to --i; return i;.
2) Equivalent to ranges::advance(i, -n); return i;.
3) Equivalent to ranges::advance(i, -n, bound); return i;.

The decremented iterator.
