hpx::fill#

Defined in header hpx/algorithm.hpp.

See Public API for a list of names and headers that are part of the public HPX API.

See also:

template<typename ExPolicy, typename FwdIter, typename T>
util::detail::algorithm_result_t<ExPolicy> hpx::fill(ExPolicy &&policy, FwdIter first, FwdIter last, T value)#

Assigns the given value to the elements in the range [first, last). Executed according to the policy.

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.

  • FwdIter – The type of the source iterators used (deduced). This iterator type must meet the requirements of an forward iterator.

  • 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 the algorithm will be applied to.

  • last – Refers to the end of 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 FwdIter, typename T>
void hpx::fill(FwdIter first, FwdIter last, T value)#

Assigns the given value to the elements in the range [first, last).

Note

Complexity: Performs exactly last - first assignments.

Template Parameters:

  • FwdIter – The type of the source iterators used (deduced). This iterator type must meet the requirements of an forward iterator.

  • T – The type of the value to be assigned (deduced).

Parameters:

  • first – Refers to the beginning of the sequence of elements the algorithm will be applied to.

  • last – Refers to the end of the sequence of elements the algorithm will be applied to.

  • value – The value to be assigned.

Returns:

The fill algorithm returns a void.
