Class BitSet

java.lang.Object
fj.data.hamt.BitSet
public final class BitSet extends Object
A sequence of bits representing a value. The most significant bit (the bit with the highest value) is the leftmost bit and has the highest index. For example, the BitSet("1011") represents the decimal number 11 and has indices [3, 0] inclusive where the bit with the lowest value has the lowest index and is the rightmost bit.
