Class FlipperShape

java.lang.Object
  gizmoball.shape.UnionShape
      gizmoball.shape.FlipperShape

All Implemented Interfaces:

Shape

public class FlipperShape
extends UnionShape
implements Shape

This class, implementing the Shape interface, represents a flipper shape, consisting of two circles connected by edges tangent to the circles. This class extends UnionShape. Representation Invariant: center1 != null and center2 != null && radius > 0
