persistence.antlr.collections.impl.BitSet
A BitSet to replace java.util.BitSet. Primary differences are that most set operators return new sets as opposed to oring and anding "in place". Further, a number of operations were added. I cannot contain a BitSet because there is no way to access the internal bits (which I need for speed) and, because it is final, I cannot subclass to add functionality. Consider defining set degree. Without access to the bits, I must call a method n times to test the ith bit...ack! Also seems like or() from util is wrong when size of incoming set is bigger than this.bits.length. @author Terence Parr @author
