Class BitSet<T>

java.lang.Object
com.ibm.wala.util.intset.BitSet<T>
@Deprecated(since="1.9.0") public final class BitSet<T> extends Object
Deprecated.
Use an IntSet such as MutableSparseIntSet or BitVectorIntSet together with an OrdinalSetMapping instead. This class has no known use within WALA.
A bit set is a set of elements, each of which corresponds to a unique integer from [0,MAX].
