Detailed Description

template<typename T, typename... OptionalFilter>
class stapl::pg_edge_view< T, OptionalFilter >

Provides a view over the input ports of an inter-paragraph dataflow backed view argument, so that point to point dataflow to tasks within a consuming paragraph can be initiated.

Template Parameters

T	The edge value type (i.e., the return type of the consumed task).
Optional	Filter Type of a functor applied to the the value produced by a task of the edge_container prior data flow to the consumer.

The underlying edge container is non templated and is agnostic to the edge value type. The edge_view informs the edge_container of the type via explicit template parameter specification when invoking methods.

Member Function Documentation

setup_flow()

template<typename T , typename... OptionalFilter>

void stapl::pg_edge_view< T, OptionalFilter >::setup_flow	(	index_type	producer_tid,
		local_notifier_t *	notifier_ptr,
		edge_container &
	)		const

Called by successor tasks to create an edge in the edge_container.

Parameters

producer_tid	The task identifier of the task to set up the data flow from.
notifier_ptr	A pointer to the notifier that should be invoked when the requested value is available on this location for consumption.

Wraps the notifier appropriately based on whether persistency is enabled or not and then redirects to edge_container::setup_flow.

operator[]()

template<typename T , typename... OptionalFilter>

reference stapl::pg_edge_view< T, OptionalFilter >::operator[]

(

index_type

producer_tid

)

const

Return a reference to the value produced by task with identifier producer_tid.

The reference is backed by an entry in value cache of the underlying edge_container.

locality()

template<typename T , typename... OptionalFilter>

constexpr locality_info stapl::pg_edge_view< T, OptionalFilter >::locality ( index_type  ) const

noexcept

Return locality information about the element specified by the gid.

Returns

A locality_qualifier, affinity specifier, as well as this object's handle and associated location for this affinity.
