Class FJoint

java.lang.Object
  fisica.FDrawable
      fisica.FJoint

Direct Known Subclasses:

FConstantVolumeJoint, FDistanceJoint, FGearJoint, FMouseJoint, FPrismaticJoint, FRevoluteJoint

public abstract class FJoint
extends FDrawable

Represents a joint between two or more bodies. A joint establishes some kind of relation between two or more bodies. Depending on the specific joint the relation might be a distance relation, a rotation relation or even a volume conservation relation. This class cannot be be instantiated, instead use one of the derived classes.
