Detailed Description

Function set for block add or removal of keys.

Certain keyframe editing operations work on group of keys rather than an single key. These operations require this function set to retrieve changes.

Function set for reading a block of keyframe changes. They are used internally to set a large group of keys quickly. Because changes occur in groups using base class keyframe methods on this derived class do not make sense. Therefore, methods describing where the block of keys were added or removed are available though methods on this class.

	)

Constructor.

Class constructor that initializes the function set to the given MObject.

Parameters:

[in]	object	The MObject to attach the function set to
[out]	ReturnStatus	the return status

Status Codes:

• MS::kSuccess if the function set is successfully attached
• MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject
