## Detailed Description

A base class for listeners that want to know about changes to an ARADocument object.

Use ARADocument::addListener() to register your listener with an ARADocument.

## Constructor & Destructor Documentation

## ◆ ~ARADocumentListener()

virtual ARADocumentListener::~ARADocumentListener | ( |  | ) |
| virtual default

Destructor.

## Member Function Documentation

## ◆ willBeginEditing()

virtual void ARADocumentListener::willBeginEditing | ( | ARADocument * | document | ) |
| virtual

Called before the document enters an editing state.

Parameters

  document | The document about to enter an editing state.

## ◆ didEndEditing()

virtual void ARADocumentListener::didEndEditing | ( | ARADocument * | document | ) |
| virtual

Called after the document exits an editing state.

Parameters

  document | The document about exit an editing state.

## ◆ willNotifyModelUpdates()

virtual void ARADocumentListener::willNotifyModelUpdates | ( | ARADocument * | document | ) |
| virtual

Called before sending model updates do the host.

Parameters

  document | The document whose model updates are about to be sent.

## ◆ didNotifyModelUpdates()

virtual void ARADocumentListener::didNotifyModelUpdates | ( | ARADocument * | document | ) |
| virtual

Called after sending model updates do the host.

Parameters

  document | The document whose model updates have just been sent.

## ◆ willUpdateDocumentProperties()

virtual void ARADocumentListener::willUpdateDocumentProperties | ( | ARADocument * | document,
|  | ARA::PlugIn::PropertiesPtr< ARA::ARADocumentProperties > | newProperties )
| virtual

Called before the document's properties are updated.

Parameters

  document | The document whose properties will be updated.
  newProperties | The document properties that will be assigned to `document`.

## ◆ didUpdateDocumentProperties()

virtual void ARADocumentListener::didUpdateDocumentProperties | ( | ARADocument * | document | ) |
| virtual

Called after the document's properties are updated.

Parameters

  document | The document whose properties were updated.

## ◆ didAddMusicalContextToDocument()

virtual void ARADocumentListener::didAddMusicalContextToDocument | ( | ARADocument * | document,
|  | ARAMusicalContext * | musicalContext )
| virtual

Called after a musical context is added to the document.

Parameters

  document | The document that `musicalContext` was added to.
  musicalContext | The musical context that was added to `document`.

## ◆ willRemoveMusicalContextFromDocument()

virtual void ARADocumentListener::willRemoveMusicalContextFromDocument | ( | ARADocument * | document,
|  | ARAMusicalContext * | musicalContext )
| virtual

Called before a musical context is removed from the document.

Parameters

  document | The document that `musicalContext` will be removed from.
  musicalContext | The musical context that will be removed from `document`.

## ◆ didReorderMusicalContextsInDocument()

virtual void ARADocumentListener::didReorderMusicalContextsInDocument | ( | ARADocument * | document | ) |
| virtual

Called after the musical contexts are reordered in an ARA document.

Musical contexts are sorted by their order index - this callback signals a change in this ordering within the document.

Parameters

  document | The document with reordered musical contexts.

## ◆ didAddRegionSequenceToDocument()

virtual void ARADocumentListener::didAddRegionSequenceToDocument | ( | ARADocument * | document,
|  | ARARegionSequence * | regionSequence )

Parameters

  document | The document that `regionSequence` was added to.
  regionSequence | The region sequence that was added to `document`.

## ◆ willRemoveRegionSequenceFromDocument()

virtual void ARADocumentListener::willRemoveRegionSequenceFromDocument | ( | ARADocument * | document,
|  | ARARegionSequence * | regionSequence )
| virtual

Called before a region sequence is removed from the document.

Parameters

  document | The document that `regionSequence` will be removed from.
  regionSequence | The region sequence that will be removed from `document`.

## ◆ didReorderRegionSequencesInDocument()

virtual void ARADocumentListener::didReorderRegionSequencesInDocument | ( | ARADocument * | document | ) |
| virtual

Called after the region sequences are reordered in an ARA document.

Region sequences are sorted by their order index - this callback signals a change in this ordering within the document.

Parameters

  document | The document with reordered region sequences.
