    • getRankings

      public List<Rankable> getRankings()
      The returned defensive copy is only "somewhat" defensive. We do, for instance, return a defensive copy of the enclosing List instance, and we do try to defensively copy any contained Rankable objects, too. However, the contract of Rankable.copy() does not guarantee that any Object's embedded within a Rankable will be defensively copied, too.
      Returns:
      a somewhat defensive copy of ranked items
