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.
