template<typename ExPolicy, typename Rng, typename T = typename std::iterator_traits<hpx::traits::range_iterator_t<Rng>>::value_type>
hpx::parallel::util::detail::algorithm_result<ExPolicy, typename hpx::traits::range_traits<Rng>::iterator_type>::type fill(ExPolicy &&policy, Rng &&rng, T const &value)# Assigns the given value to the elements in the range [first, last).
The comparisons in the parallel fill algorithm invoked with an execution policy object of type sequenced_policy execute in sequential order in the calling thread.
The comparisons in the parallel fill algorithm invoked with an execution policy object of type parallel_policy or parallel_task_policy are permitted to execute in an unordered fashion in unspecified threads, and indeterminately sequenced within each thread.
Note
Complexity: Performs exactly last - first assignments.
- Template Parameters
ExPolicy – The type of the execution policy to use (deduced). It describes the manner in which the execution of the algorithm may be parallelized and the manner in which it executes the assignments.
Rng – The type of the source range used (deduced). The iterators extracted from this range type must meet the requirements of an input iterator.
T – The type of the value to be assigned (deduced).
- Parameters
policy – The execution policy to use for the scheduling of the iterations.
rng – Refers to the sequence of elements the algorithm will be applied to.
value – The value to be assigned.
- Returns
The fill algorithm returns a hpx::future<void> if the execution policy is of type sequenced_task_policy or parallel_task_policy and returns difference_type otherwise (where difference_type is defined by void.

template<typename ExPolicy, typename Iter, typename Sent, typename T = typename std::iterator_traits<Iter>::value_type>
hpx::parallel::util::detail::algorithm_result<ExPolicy, Iter>::type fill(ExPolicy &&policy, Iter first, Sent last, T const &value)# Assigns the given value to the elements in the range [first, last).
The comparisons in the parallel fill algorithm invoked with an execution policy object of type sequenced_policy execute in sequential order in the calling thread.
The comparisons in the parallel fill algorithm invoked with an execution policy object of type parallel_policy or parallel_task_policy are permitted to execute in an unordered fashion in unspecified threads, and indeterminately sequenced within each thread.
Note
Complexity: Performs exactly last - first assignments.
- Template Parameters
ExPolicy – The type of the execution policy to use (deduced). It describes the manner in which the execution of the algorithm may be parallelized and the manner in which it executes the assignments.
Iter – The type of the source iterators used for the range (deduced).
Sent – The type of the source sentinel (deduced). This sentinel type must be a sentinel for InIter.
T – The type of the value to be assigned (deduced).
- Parameters
policy – The execution policy to use for the scheduling of the iterations.
first – Refers to the beginning of the sequence of elements of the range the algorithm will be applied to.
last – Refers to the end of the sequence of elements of the range the algorithm will be applied to.
value – The value to be assigned.
- Returns
The fill algorithm returns a hpx::future<void> if the execution policy is of type sequenced_task_policy or parallel_task_policy and returns difference_type otherwise (where difference_type is defined by void.

- Parameters
