scala
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`. Sort of acts like a sequence also (supports length and contains). For example:

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

Method Summary
`def` | apply (idx : Int) : Int
`def` | by (step : Int) : Range create a new range with the start and end values of this range and a new `step`
`def` | contains (x : Int) : Boolean a `Seq.contains`, not a `Iterator.contains`!
`override def` | contains (elem : Any) : Boolean a `Iterator.contains`, not a `Seq.contains`!
`override def` | hasNext : Boolean Does this iterator provide another element?
`def` | length : Int
`override def` | next : Int Returns the next element.
`override def` | peekList (sz : Int) : Seq[Int] returns the first `sz` elements that will be iterated by this iterator, or fewer if the iterator has less elements left to iterate over
`def` | seqOfRange : Projection[Int]
