  Class
  Description
  `class`
  `DeserializerComparator<T>`
  A `RawComparator` that uses a `Deserializer` to deserialize the objects to be compared so that the standard `Comparator` can be used to compare them.
  `class`
  `JavaSerializationComparator<T extends Serializable & Comparable<T>>`
  A `RawComparator` that uses a `JavaSerialization` `Deserializer` to deserialize objects that are then compared via their `Comparable` interfaces.
