Interface TupleComparator

All Superinterfaces:

Comparator<Tuple>

public interface TupleComparator
extends Comparator<Tuple>

Comparator defines sort total order of tuples: that is given two tuples t1, t2; 1. when t1.equals(t2), compare(t1, t2) = 0, that is, compare(t1, t1) = 0 2. when t1.compare(t1, t2) < 0, t2.compare(t1) > 0. (reflexible) 3. if compare(t1, t2) < 0 and compare(t2, t3) < 0, then compare(t1, t3) < 0 (transitivity)
