Class Path

  • public class Path
extends java.lang.Object
    Paths define shapes, trajectories, and regions of all sorts. They shall be used to draw lines, define the shapes of filled areas, and specify boundaries for clipping other graphics. A path shall be composed of straight and curved line segments, which may connect to one another or may be disconnected.
    Since:
    5.5.6
