Detailed Description

Abstract base class for all inports An Inport can be connected to an Outport. The approved connection can be determined by the canConnectTo function.

Member Function Documentation

◆ invalidate()

void inviwo::Inport::invalidate ( InvalidationLevel invalidationLevel )

protectedvirtual

Called by Outport::invalidate on its connected inports, which is call by Processor::invalidate. Will by default invalidate its processor. From above in the network.

◆ isChanged()

bool inviwo::Inport::isChanged ( ) const

virtual

An inport is changed when it has new data, and it's processor has not been processed.

◆ isReady()

bool inviwo::Inport::isReady ( ) const

overridevirtual

An inport is ready when it is connected, and it's outports are ready.

See also: Outport::isReady

Implements inviwo::Port.

◆ onChange()

template<typename T >

const BaseCallBack * inviwo::Inport::onChange	(	T *	o,
		void(T::*)()	m
	)

The on change call back is invoked before Processor::process after a port has been connected, disconnected, or has changed its validation level. Note it is only called if process is also going to be called.

◆ onInvalid()

template<typename T >

const BaseCallBack * inviwo::Inport::onInvalid	(	T *	o,
		void(T::*)()	m
	)

the onInvalid callback is called directly after the port has been invalidated. It's only called once for each transition from valid to invalid.

◆ propagateEvent()

void inviwo::Inport::propagateEvent	(	Event *	event,
		Outport *	target = `nullptr`
	)

virtual

Propagate event upwards towards connected outports, if targets is nullptr, propagate the even to all connected outport, otherwise only to target.

◆ readyUpdate()

void inviwo::Inport::readyUpdate ( )

protected

Called by the connected outports to let the inport know that their ready status has changed.

◆ setOptional()

void inviwo::Inport::setOptional ( bool optional )

An inport can be set optional, in which case the processor will by default be ready even if no outport is connected. This means that an optional inport may not have any connected outports when evaluating the ProcessorNetwork, i.e. when Processor::process() is called. Hence one needs to check manually that the port isReady before using it.

See also: isReady

◆ setValid()

void inviwo::Inport::setValid ( const Outport * source )

protectedvirtual

Called by Outport::setValid, which is call by Processor::setValid, which is called after Processor:process. From above in the network.
