qx.util.range
Class IntegerRange

java.lang.Object
  qx.core.Object
      qx.util.range.IntegerRange

public class IntegerRange
extends Object

Create a list of successive integers.

WARNING: Experimental! Most likely to change in the future. May be pimped up by ideas from http://www.mochikit.com/doc/html/MochiKit/Iter.html#fn-range or consolidated with Range

The constructor can take a negative step width, or start greater than stop, to create decreasing ranges.

  var r = new qx.util.range.IntegerRange(1,20);
  var i;
  while ((i = r.next())!=null) { alert(i) }; // yields 1,2,3,..,20
