Class LayoutShape

  • public class LayoutShape
extends java.lang.Object
    A LayoutShape is a set of LayoutShapePoint used to draw a shape. Each point can ether be a point on the shape or a control point that defines a curve that's part of the shape. The shape can be open (end points not connected) or closed (end points connected)
