std::experimental::ranges::sort(3) C++ Standard Libary std::experimental::ranges::sort(3)

NAME

std::experimental::ranges::sort - std::experimental::ranges::sort

Synopsis


Defined in header <experimental/ranges/algorithm>
template< RandomAccessIterator I, Sentinel<I> S,


class Comp = ranges::less<>, class Proj = ranges::identity> (1) (ranges TS)
requires Sortable<I, Comp, Proj>


I sort( I first, S last, Comp comp = Comp{}, Proj proj = Proj{} );
template< RandomAccessRange R,


class Comp = ranges::less<>, class Proj = ranges::identity>
requires Sortable<ranges::iterator_t<R>, Comp, Proj> (2) (ranges TS)


ranges::safe_iterator_t<R> sort( R&& r, Comp comp = Comp{}, Proj
proj = Proj{} );


1) Sorts the elements in the range [first, last) in ascending order. The order of
equal elements is not guaranteed to be preserved. Elements are compared using comp
after applying the projection proj.
2) Sorts the elements in the range r, as if by return ranges::sort(ranges::begin(r),
ranges::end(r), comp, proj);


Notwithstanding the declarations depicted above, the actual number and order of
template parameters for algorithm declarations is unspecified. Thus, if explicit
template arguments are used when calling an algorithm, the program is probably
non-portable.

Parameters


first, last - the range of elements to sort
r - the range of elements to sort
comp - the comparator to use
proj - the projection to apply to elements in the range

Return value


An iterator pointing past the end of the range (i.e., it compares equal to last for
overload (1), and ranges::end(r) for overload (2)).

Complexity


O(N·log(N)) comparisons, where N is equal to the number of elements in the range.
