org.openscience.cdk.renderer.elements.path.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();
