Detailed Description

template<typename WF>
struct stapl::paragraph_impl::compute_demotion_wf< WF >

Functor that recovers the original workfunction passed to task creation prior to any wrappers to support the promotion of localized return values.

Template Parameters

WF	The type of the workfunction that is held in a Task that may have been transformed to support promotion.

The functor supports task migration, allowing the original workfunction to be recovered to be paired with the original, non localized viewset. Localization will be attempted again on the new execution location, once migration has completed.

Primary template matches case where promote_wf wrapper was not applied. Return the input parameter.
