Class IntersectionObject

java.lang.Object
  carmetal.objects.ConstructionObject
      carmetal.objects.PointObject
          carmetal.objects.IntersectionObject

All Implemented Interfaces:

DriverObject, MoveableObject, carmetal.rene.lister.Element, carmetal.rene.util.sort.SortObject, Cloneable

Direct Known Subclasses:

AxisFunctionIntersectionObject, CircleIntersectionObject, LineCircleIntersectionObject, LineIntersectionObject, LineQuadricIntersectionObject, PointonObjectIntersectionObject

public class IntersectionObject
extends PointObject

This is the parent class of various intersection objects. Intersections are points. Problems are multiple intersections and restrictions to keep one of them away or close to some other point. The most problematic intersections are between objects of type PointonObject. In case of two possible intersection points, there is also the option to switch from one object to the other in automatic tracks. This allows to run through all possible states of a construction.
