IAAFDescriptiveMarker Interface Reference

Detailed Description

The IAAFDescriptiveMarker interface is implemented by objects which represent a descriptive metadata associated with a point in time.

A DescriptiveMarker may contain a DescriptiveFramework object that specifies the metadata.

In addition to the specific error results listed for each method, all methods in this interface may also return one of the following values:

AAFRESULT_NOMEMORY

• insufficient system memory is available to perform the operation.

AAFRESULT_NOT_INITIALIZED

• This object has not yet had Initialize() called on it through this object's primary interface. Note that IAAFMobSlot is a primary interface for an abstract class, so it is not appropriate for the Initialize() method to exist in this interface. The Initialize() method is available through the concrete object's primary interface.

Objects that implement IAAFDescriptiveMarker also implement the following interfaces:

• IAAFCommentMarker
• IAAFEvent
• IAAFSegment
• IAAFComponent
• IAAFComponent2
• IAAFObject

Member Function Documentation

HRESULT IAAFDescriptiveMarker::GetDescribedSlotIDs (  [in] aafUInt32  numberElements, [in] aafUInt32 *  pDescribedSlotIDs )

Parameters: numberElements  [in] Number of elements in the pDescribedSlotIDs array pDescribedSlotIDs  [in] Array of channel IDs

HRESULT IAAFDescriptiveMarker::GetDescribedSlotIDsSize (  [out] aafUInt32 *  numberElements  )

Parameters: numberElements  [out] Number of elements in the pDescribedSlotIDs array

HRESULT IAAFDescriptiveMarker::GetDescriptiveFramework (  [out, retval] IAAFDescriptiveFramework **  ppDescriptiveFramework  )

Parameters: ppDescriptiveFramework  [out,retval] DescriptorFramework object to return

HRESULT IAAFDescriptiveMarker::Initialize (   )

Initializes a newly allocated, IAAFDescriptiveFrame object. This method must be called after allocation, and before any other method can be called. Return codes: AAFRESULT_SUCCESS succeeded. (This is the only code indicating success.) AAFRESULT_ALREADY_INITIALIZED Initialize() has already been called on this object.

HRESULT IAAFDescriptiveMarker::SetDescribedSlotIDs (  [in] aafUInt32  numberElements, [in] aafUInt32 *  pDescribedSlotIDs )

Parameters: numberElements  [in] Number of elements in the pDescribedSlotIDs array pDescribedSlotIDs  [in] Array of slot IDs

HRESULT IAAFDescriptiveMarker::SetDescriptiveFramework (  [in] IAAFDescriptiveFramework *  pDescriptiveFramework  )

Parameters: pDescriptiveFramework  [in] DescriptorFramework object to set
