      • compare

        public abstract int compare​(int slot1,
                                    int slot2)
        Compare hit at slot1 with hit at slot2.
        slot1 - first slot to compare
        slot2 - second slot to compare
        any N < 0 if slot2's value is sorted after slot1, any N > 0 if the slot2's value is sorted before slot1 and 0 if they are equal
      • value

        public abstract T value​(int slot)
        Return the actual value in the slot.
        slot - the value
        value in this slot
      • compareValues

        public int compareValues​(T first,
                                 T second)
        Returns a negative integer if first is less than second, 0 if they are equal and a positive integer otherwise. Default impl to assume the type implements Comparable and invoke .compareTo; be sure to override this method if your FieldComparator's type isn't a Comparable or if your values may sometimes be null
