Detailed Description

The IAAFTransition interface is implemented by objects describe a change or transition from one piece of essence to another.

Transitions must exist in the context of a sequence, and must be surrounded on both sides by segments (an object which has an IAAFSegment interface).

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

AAFRESULT_NOT_INITIALIZED

This object has not yet had Initialize() called on it through this object's primary interface. Note that IAAFMob 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 IAAFTransition also implement the following interfaces:

Member Function Documentation

HRESULT IAAFTransition::GetCutPoint ( [out] aafPosition_t * cutPoint )

Gets the point at which a cut would be inserted if the transition were removed.

Parameters:

cutPoint [out] Cut Point

HRESULT IAAFTransition::GetOperationGroup ( [out] IAAFOperationGroup ** groupObj )

Gets the OperationGroup associated with the transition.

Parameters:

groupObj [out] OperationGroup used by transition

cutPoint	[in] The point at which a cut would be inserted if the transition were removed
op	[in] A reference to an operation group object

HRESULT IAAFTransition::SetCutPoint ( [in] aafPosition_t cutPoint )

Sets the point at which a cut would be inserted if the transition were removed.

Parameters:

cutPoint [in] Cut Point

HRESULT IAAFTransition::SetOperationGroup ( [in] IAAFOperationGroup * opgroup )
