      Emits the comparator used to order this set, or null if it obeys its elements' natural ordering (Object), followed by the size of the set (the number of elements it contains) (int), followed by all of its elements (each an Object) in order (as determined by the set's Comparator, or by the elements' natural ordering if the set has no Comparator).
      
      Throws:
      
      java.io.IOException - in case of IO problems
