## Detailed Description

Extension class meant to be subclassed by the plugin's implementation of.

See also
  AudioProcessor.

Subclassing AudioProcessorARAExtension allows access to the three possible plugin instance roles as defined by the ARA SDK. Hosts can assign any subset of roles to each plugin instance.

## Member Function Documentation

## ◆ getPlaybackRenderer()

template<typename PlaybackRenderer_t = ARAPlaybackRenderer>

PlaybackRenderer_t * AudioProcessorARAExtension::getPlaybackRenderer | ( |  | ) | const
| noexcept

Returns the result of ARA::PlugIn::PlugInExtension::getPlaybackRenderer() with the pointer cast to ARAPlaybackRenderer*.

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

## ◆ getEditorRenderer()

template<typename EditorRenderer_t = ARAEditorRenderer>

EditorRenderer_t * AudioProcessorARAExtension::getEditorRenderer | ( |  | ) | const
| noexcept

Returns the result of ARA::PlugIn::PlugInExtension::getEditorRenderer() with the pointer cast to ARAEditorRenderer*.

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

## ◆ getEditorView()

template<typename EditorView_t = ARAEditorView>

EditorView_t * AudioProcessorARAExtension::getEditorView | ( |  | ) | const
| noexcept

Returns the result of ARA::PlugIn::PlugInExtension::getEditorView() with the pointer cast to ARAEditorView*.

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

## ◆ isPlaybackRenderer()

bool AudioProcessorARAExtension::isPlaybackRenderer | ( |  | ) | const
| noexcept

Returns true if plugin instance fulfills the ARAPlaybackRenderer role.

## ◆ isEditorRenderer()

bool AudioProcessorARAExtension::isEditorRenderer | ( |  | ) | const
| noexcept

Returns true if plugin instance fulfills the ARAEditorRenderer role.

## ◆ isEditorView()

bool AudioProcessorARAExtension::isEditorView | ( |  | ) | const
| noexcept

Returns true if plugin instance fulfills the ARAEditorView role.

## ◆ getTailLengthSecondsForARA()

bool AudioProcessorARAExtension::getTailLengthSecondsForARA | ( | double & | tailLength | ) | const
| protected

Implementation helper for AudioProcessor::getTailLengthSeconds().

If bound to ARA, this traverses the instance roles to retrieve the respective tail time and returns true. Otherwise returns false and leaves tailLength unmodified.

## ◆ prepareToPlayForARA()

bool AudioProcessorARAExtension::prepareToPlayForARA | ( | double | sampleRate,
|  | int | samplesPerBlock,
|  | int | numChannels,
|  | AudioProcessor::ProcessingPrecision | precision )
| protected

Implementation helper for AudioProcessor::prepareToPlay().

If bound to ARA, this traverses the instance roles to prepare them for play and returns true. Otherwise returns false and does nothing.

## ◆ releaseResourcesForARA()

bool AudioProcessorARAExtension::releaseResourcesForARA | ( |  | ) |
| protected

Implementation helper for AudioProcessor::releaseResources().

If bound to ARA, this traverses the instance roles to let them release resources and returns true. Otherwise returns false and does nothing.

## ◆ processBlockForARA() [1/2]

bool AudioProcessorARAExtension::processBlockForARA | ( | AudioBuffer< float > & | buffer,
|  | AudioProcessor::Realtime | realtime,
|  | const AudioPlayHead::PositionInfo & | positionInfo )
| protected

Implementation helper for AudioProcessor::processBlock().

If bound to ARA, this traverses the instance roles to let them process the block and returns true. Otherwise returns false and does nothing.

Use this overload if your rendering code already has a current positionInfo available.

## ◆ processBlockForARA() [2/2]

bool AudioProcessorARAExtension::processBlockForARA | ( | AudioBuffer< float > & | buffer,
|  | AudioProcessor::Realtime | isNonRealtime,
|  | AudioPlayHead * | playhead )
| protected

Implementation helper for AudioProcessor::processBlock().

If bound to ARA, this traverses the instance roles to let them process the block and returns true. Otherwise returns false and does nothing.

Use this overload if your rendering code does not have a current positionInfo available.

## ◆ didBindToARA()

void AudioProcessorARAExtension::didBindToARA | ( |  | ) |
| override protected noexcept

Optional hook for derived classes to perform any additional initialization that may be needed.

If overriding this, make sure you call the base class implementation from your override.
