Member Function Documentation

set_result_impl()

template<typename Return, bool b_has_span = false>

void stapl::detail::result_manager< Return, b_has_span >::set_result_impl	(	std::size_t	,
		task_graph::task_id_t	task_id,
		task_graph &	tg
	)

Signature for non-void return types. Redirect to the edge_container.

set_os_result_notifier()

template<typename Return, bool b_has_span = false>

os_td_wait_t* stapl::detail::result_manager< Return, b_has_span >::set_os_result_notifier	(	task_graph &	tg,
		result_type &
	)

If the return type of the paragraph is non-void, initializes an instance of one_sided_wait_td_notifier to tie parent paragraph notification to both this paragraph's dataflow and termination detection.

finalize_result()

template<typename Return, bool b_has_span = false>

result_type& stapl::detail::result_manager< Return, b_has_span >::finalize_result

(

result_type &

res

)

For the primary class template, this method is an identity op.

Parameters

res	The PARAGRAPH result from this location.
