Detailed Description

Base function set for keyframe deltas.

Keyframe delta objects are returned via the MAnimMessage::animKeyframeEditedCallback( ... ). They describe atomic changes to keyframes as a result of a curve edit operation. Refer to the documentation in MAnimMessage class for further information.

Base function set for all keyframe delta objects. A keyframe delta object is generated from the MAnimMessage::addAnimKeyframeEditedCallback.
