Class XYCurve.Itr

java.lang.Object

de.lmu.ifi.dbs.elki.math.geometry.XYCurve.Itr

Enclosing class:

XYCurve

public class XYCurve.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());
 }
