Class ProgressListener

java.lang.Object
  nl.knowledgeplaza.util.ProgressListener

public abstract class ProgressListener
extends java.lang.Object

A class to provide progress feedback. The class does not dictate what the listened to process will provide for feedback. It may or may not class begin, done or init. That depends on the implementation in the process that is monitored. Progress is called always, but it is undefined how often, that -again- depends on the implementation in the process that is monitored. An actual progress listener should extend this class. It can override the neccesary methods and do with the information what is appropriate for the context. For example: - the information can be printed on System.out - in a Swing application the information can be forwarded to a MonitorProgress component. This is implemented as a abstract class and not an interface, so that future changes will not required existing code to be modified.
