public class Message

extends java.lang.Object

implements java.io.Serializable

A message class for sending data across the network: defines message types and constructors for messages. A message is just a type plus a list of fields for the message, you can interpret it however you want.

This might be done more cleanly with an abstract message class and subclasses for different types, but since there is no processing associated with message types, this implementation is simpler!
