This marshaller treats well-known objects that need marshalling - such as MethodCall , Fqn , DataVersion , and even some JDK objects such as String , List , Boolean and others as types that do not need complete class definitions. Instead, each of these well-known types are represented by a short , which is a lot more efficient.

In addition, reference counting is done to reduce duplication of writing certain objects multiple times, to help keep the streams small and efficient.
