public class Scale
extends Node
implements Transformation

A Scale node scales the local coordinate system using the scaling factors scaleX, scaleY and scaleZ. In general, the scaling factors may differ. However, there is the constructor Scale(float) which initializes the three factors with the same value such that a uniform scaling is performed.
This class declares two predicates: Scale.Pattern allows one to write Scale(x,y,z) in a pattern of an XL query. Scale.XPattern is useful for uniform Scale nodes since it allows one to write Scale(x) in a pattern. It uses scaleX to obtain the value for the predicate argument.
