7.  def thenBy[S](f: (T) ⇒ S)(implicit arg0: Ordering[S]): Ordering[T]

   Returns a new Ordering which compares elements by applying a function (f) to them if this Ordering returned 0 when comparing them.

   Returns a new Ordering which compares elements by applying a function (f) to them if this Ordering returned 0 when comparing them.

   This method is an alias of thenOrderingBy, intended to be used when chaining several calls in order to reduce verbosity, as in the following example:

   case class IntTuple(a: Int, b: Int, c: Int, d: Int)
   
   object IntTuple {
     val ordering: Ordering[IntTuple] =
       Ordering.by[IntTuple, Int](_.a)
         .thenBy(_.b)
         .thenBy(_.c)
         .thenBy(_.d)
   }

   S

   the return type of f

   f

   a function mapping elements to some value to be compared

   returns

   a new Ordering which compares elements by applying a function to them if this Ordering returned 0 when comparing them

8.  def thenOrderingBy[S](f: (T) ⇒ S)(implicit arg0: Ordering[S]): Ordering[T]

   Returns a new Ordering which compares elements by applying a function (f) to them if this Ordering returned 0 when comparing them.

   Returns a new Ordering which compares elements by applying a function (f) to them if this Ordering returned 0 when comparing them.

   This method is intended to be used to build more complex Orderings from other Orderings, as in the following example:

   case class PlayingCard(rank: Rank, suit: Suit)
   
   object PlayingCard {
     val rankOnlyOrdering: Ordering[PlayingCard] = Ordering.by(_.rank)
     val fullOrdering: Ordering[PlayingCard] = rankOnlyOrdering.thenOrderingBy(_.suit)
   }

   S

   the return type of f

   f

   a function mapping elements to some value to be compared

   returns

   a new Ordering which compares elements by applying a function to them if this Ordering returned 0 when comparing them
