Detailed Description

Base class representing an ARA region sequence.

Member Typedef Documentation

PropertiesPtr

using ARARegionSequence::PropertiesPtr = ARA::PlugIn::PropertiesPtr<ARA::ARARegionSequenceProperties>

Listener

using ARARegionSequence::Listener = ARARegionSequenceListener

Member Function Documentation

getDocument()

template<typename Document_t = ARADocument>

Document_t * ARARegionSequence::getDocument ( ) const

noexcept

Returns the result of ARA::PlugIn::RegionSequence::getDocument() with the pointer cast to ARADocument*.

If you have overridden ARADocumentControllerSpecialisation::doCreateDocument(), then you can use the template parameter to cast the pointers to your subclass of ARADocument.

getMusicalContext()

template<typename MusicalContext_t = ARAMusicalContext>

MusicalContext_t * ARARegionSequence::getMusicalContext ( ) const

noexcept

Returns the result of ARA::PlugIn::RegionSequence::getMusicalContext() with the pointer cast to ARAMusicalContext*.

If you have overridden ARADocumentControllerSpecialisation::doCreateMusicalContext(), then you can use the template parameter to cast the pointers to your subclass of ARAMusicalContext.

getPlaybackRegions()

template<typename PlaybackRegion_t = ARAPlaybackRegion>

const std::vector< PlaybackRegion_t * > & ARARegionSequence::getPlaybackRegions ( ) const

noexcept

Returns the result of ARA::PlugIn::RegionSequence::getPlaybackRegions() with the pointers within cast to ARAPlaybackRegion*.

If you have overridden ARADocumentControllerSpecialisation::doCreatePlaybackRegion(), then you can use the template parameter to cast the pointers to your subclass of ARAPlaybackRegion.

getNumChildren()

size_t ARARegionSequence::getNumChildren ( ) const

overridevirtualnoexcept

Returns the number of ARA model objects aggregated by this object.

Objects that are merely referred to, but not aggregated by the current object are not included in this count, e.g. a referenced RegionSequence does not count as a child of the referring PlaybackRegion.

See the ARA documentation's ARA Model Graph Overview for more details.

Implements ARAObject.

getChild()

ARAObject * ARARegionSequence::getChild ( size_t index )

overridevirtual

Returns the child object associated with the given index.

The index should be smaller than the value returned by getNumChildren().

Note that the index of a particular object may change when the ARA model graph is edited.

Implements ARAObject.

getParent()

ARAObject * ARARegionSequence::getParent ( )

overridevirtual

Returns the ARA model object that aggregates this object.

Returns nullptr for the ARADocument root object.

Implements ARAObject.

visit()

void ARARegionSequence::visit ( ARAObjectVisitor & visitor )

overridevirtual

Allows the retrieval of the concrete type of a model object.

To use this, create a new class derived from ARAObjectVisitor and override its functions depending on which concrete types you are interested in.

Calling this function inside the function passed to ARAObject::traverse() allows you to map the entire ARA model graph.

Implements ARAObject.

References ARAObjectVisitor::visitRegionSequence().

getTimeRange()

Range< double > ARARegionSequence::getTimeRange

(

ARAPlaybackRegion::IncludeHeadAndTail

includeHeadAndTail = ARAPlaybackRegion::IncludeHeadAndTail::no

)

const

Returns the playback time range covered by the regions in this sequence.

Parameters

includeHeadAndTail

Whether or not the range includes the playback region's head and tail time.

getCommonSampleRate()

double ARARegionSequence::getCommonSampleRate

(

)

const

If all audio sources used by the playback regions in this region sequence have the same sample rate, this rate is returned here, otherwise 0.0 is returned.

If the region sequence has no playback regions, this also returns 0.0.
