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