Class PathBuilder

  • public class PathBuilder
extends Object
    Builder class for paths. All methods for constructing path elements return a reference to the builder, so that it can be used like: 
      PathBuilder builder = new PathBuilder();
  builder.moveTo(p1).lineTo(p1).close();
  GeneralPath path = builder.createPath();
