Class PointsToBitVector

java.lang.Object
  soot.util.BitVector
      soot.jimple.spark.sets.PointsToBitVector

public class PointsToBitVector
extends BitVector

An extension of a bit vector which is convenient to use to represent points-to sets. Used by SharedHybridSet. We have to extend soot.util.BitVector rather than java.util.BitSet because PointsToSetInternal.getBitMask() returns a soot.util.BitVector. which must be combined with other bit vectors.
