Class IntBitSet

java.lang.Object

regexodus.ds.IntBitSet

public class IntBitSet
extends Object

An implementation of BitSet (that does not technically extend BitSet due to BitSet not existing under GWT) using 32-bit sections instead of the normal 64-bit (again, for GWT reasons; 64-bit integer math is slower on GWT). Created by Tommy Ettinger on 3/30/2016.
