Detailed Description

A processor generally performs operation on input data and outputs the new result.

It can hold arbitrary number of inports and outports, as well as properties which can be used to customize the processors behavior.

A typical flow for processing Processor 1 is shown below.

Constructor & Destructor Documentation

◆ Processor()

inviwo::Processor::Processor	(	std::string_view	identifier = "",
		std::string_view	displayName = "" )

Processor constructor, takes two optional arguments.

Parameters

identifier	Should only contain alpha numeric characters, "-", "_" and " ".

Member Function Documentation

◆ addInteractionHandler()

void inviwo::Processor::addInteractionHandler ( InteractionHandler * interactionHandler )

Adds the interaction handler such that it receives events propagated to the processor. Will not add the interaction handler if it has been added before.

Note: The processor will not take ownership of the interaction handler.

See also: InteractionHandler

Parameters

interactionHandler Interaction handler to be added.

◆ addPort() [1/3]

template<typename T , typename std::enable_if_t< std::is_base_of< Outport, T >::value, int > >

T & inviwo::Processor::addPort	(	std::unique_ptr< T >	port,
		std::string_view	portGroup = "default" )

Add port to processor and pass ownership to processor.

Note: Port group is a concept for event propagation. Currently only used for ResizeEvents, which only propagate from outports to inports in the same port group

Parameters

port	to add
portGroup	name of group to propagate events through (defaults to "default")

◆ addPort() [2/3]

template<typename T , typename std::enable_if_t< std::is_base_of< Outport, T >::value, int > = 0>

T & inviwo::Processor::addPort	(	std::unique_ptr< T >	port,
		std::string_view	portGroup = "default" )

Add port to processor and pass ownership to processor.

Note: Port group is a concept for event propagation. Currently only used for ResizeEvents, which only propagate from outports to inports in the same port group

port	to add
portGroup	name of group to propagate events through (defaults to "default")

◆ addPort() [3/3]

template<typename T >

T & inviwo::Processor::addPort	(	T &	port,

◆ invalidate()

virtual void inviwo::Processor::invalidate	(	InvalidationLevel	invalidationLevel,
		Property *	modifiedProperty = nullptr )

overridevirtual

Triggers invalidation. Perform only full reimplementation of this function, meaning never call Processor::invalidate() in your reimplemented invalidation function. The general scheme is that the processor will invalidate is self and it's outports the outports will in turn invalidate their connected inports, which will invalidate their processors. Hence all processors that depend on this one in the network will be invalidated.

Reimplemented from inviwo::PropertyOwner.

Reimplemented in inviwo::PoolProcessor, and inviwo::ProcessorTrampoline.

◆ invokeEvent()

virtual void inviwo::Processor::invokeEvent ( Event * event )

overridevirtual

Reimplemented from inviwo::PropertyOwner.

◆ isConnectionActive()

virtual bool inviwo::Processor::isConnectionActive	(	Inport *	inport,
		Outport *	outport ) const

inlinevirtual

Return true if ProcessorNetworkEvaluator should evaluate the connection during ProcessorNetwork traversal. An inactive connection will propagate invalidations and events but will not be processed. Useful if the Processor has states in which it does not use an inport.

Parameters

inport	This processor's inport
outport	Another processor's outport

See also: InputSelector for an example

Reimplemented in inviwo::ImageLayoutGL, inviwo::InputSelector< InportType, OutportType >, and inviwo::Layout.

◆ isReady()

bool inviwo::Processor::isReady ( ) const

Returns whether the processor is ready to be processed. By default this will call allInportsAreReady. This behavior can be customized by setting the isReady_ update functor.

See also: StateCoordinator; allInportsAreReady

◆ isSink()

bool inviwo::Processor::isSink ( ) const

Returns whether the processor is a sink. I.e. whether it pulls data from the network. By default a processor is a sink if it has no outports. This behavior can be customized by setting the isSink_ update functor. For a processor to be evaluated there have to be a sink among its descendants.

See also: StateCoordinator

◆ isSource()

bool inviwo::Processor::isSource ( ) const

Returns whether the processor is a source. I.e. whether it brings data into the network. By default a processor is a source if it has no inports. This behavior can be customized by setting the isSource_ update functor.

See also: StateCoordinator

◆ onIdentifierChange()

NameDispatcherHandle inviwo::Processor::onIdentifierChange ( std::function< void(std::string_view, std::string_view)> callback )

Get notified when the processor identifier changes. The callback happens after the identifier is changed.

Parameters

callback gets called with the new and the old identifier respectively.

◆ process()

virtual void inviwo::Processor::process ( )

inlinevirtual

Deriving classes should override this function to do the main work of the processor. This function is called by the ProcessorNetworkEvaluator when the network is evaluated and the processor is invalid, i.e. some of its inports or properties has been modified, and is ready i.e. all non optional inports have valid data.
