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.

Function set type.
Return the class type : MFn::kKeyframeDelta.
Reimplemented from MFnBase.
Reimplemented in MFnKeyframeDeltaTangent, MFnKeyframeDeltaBlockAddRemove, MFnKeyframeDeltaInfType, MFnKeyframeDeltaMove, MFnKeyframeDeltaAddRemove, MFnKeyframeDeltaScale, MFnKeyframeDeltaBreakdown, and MFnKeyframeDeltaWeighted.

The index of this key on the animation curve.
Note that when keys are added and then moved in a single action, the delta for the added key may refer to a key that no longer exists. In this case, the index returned related to the add operation will be the index where the key would be if it still existed on the curve. For example, if an animation curve has keys at frames 1 and 10, and a key is added at frame 12 and then moved to frame 11 in a single action, when the callback for the addition is received, the key at frame 12 will no longer exist. In this case, the keyIndex returned will be 3, to indicate that the key would be at index 3 if it existed.
