class Range

[source: scala/Range.scala]

class Range(val start : Int, val end : Int, val step : Int)
extends BufferedIterator[Int]

The Range class represents integer values in range [start;end) with non-zero step value step. For example:

     val r1 = Iterator.range(0, 10)
     val r2 = Iterator.range(r1.start, r1.end, r1.step + 1)
     println(r2.length) // = 5
