Class RegionDelta

A RegionDelta represents a change in the state of a Region, holding the state before and after some change. They are in some sense complementary to Joints: In the same way that you can use Filters to examine Joints, you can use RegionDeltas to examine Filters. See also Filter::isSwitchedBy(RegionDelta *) and related methods.
