Classes:

• MessageHandler: The class MessageHandler contains the static methods log and error which should be used for any end user information instead of System.out.print() or System.err.print(). The class defines several output methods: writing to the screen (default), logging to a file, creating message events and repressing all output.

• MessageListener: For situations, where the messages Fop directs to the user have to be handled in some special way, the interface MessageListener and the class MessageEvent are provided. Embedding Fop into a graphical user interface could be such a scenario. Any MessageListener listens for MessageEvents, which contain the user message and also the message type information (progress information or error warning). The class DefaultMessageListener shows an trivial implementation of MessageListener.
• MessageEvent: a container for the text and the type of a message MessageEvents are created by MessageHandler and can be received by any MessageListener, which is added to MessageHandler;
• DefaultMessageListener: A trivial implementation of a MessageListener.
