Class XYPlot.Curve.Itr

  • Enclosing class:
    XYPlot.Curve
    public class XYPlot.Curve.Itr
extends java.lang.Object
    Iterator for the curve. 2D, does not follow Java collections style. The reason is that we want to have #getX() and #getY() operations, which does not work consistently with Java's next() style of iterations. Instead, use this style of iteration: 
     
 for (XYCurve.Itr it = curve.iterator(); it.valid(); it.advance()) {
   doSomethingWith(it.getX(), it.getY());
 }
