public abstract class AbstractMessage
extends java.lang.Object

This is a generic message implementation. Messages normally are used by observed objects when calling the update() method of the observers (but there are also other usage scenarios possible). Thus it is possible to send the reason for the update() call. Messages have a message code containing the reason for the update. Also there is the possibility to append an Object to the message with more detailed information. The message codes and the usage of the appended object are defined within the children of this class.
