class BitSet
[source: scala/collection/immutable/BitSet.scala]
abstract class BitSet
extends Set[Int] with BitSet with BitSetTemplate[BitSet]
a base class for immutable bit sets

Method Summary
def + (elem : Int) : BitSet
Adds element to bitset, returning a new set.

override def empty : BitSet
def fromArray (elems : Array[Long]) : BitSet
Create a new set of this kind from an array of longs
protected abstract def updateWord (idx : Int, w : Long) : BitSet
Update word at index `idx`; enlarge set if `idx` outside range of set
