Class ConfigurationChangeEvent

java.lang.Object
  java.util.EventObject
      de.fhg.igd.logging.ConfigurationChangeEvent

All Implemented Interfaces:

Serializable

public class ConfigurationChangeEvent

extends EventObject

Instances of this EventObject will be fired to every registered ConfigurationChangeListener. It contains the type of operation that has been carried out on the LoggingConfiguration, as well as further information about the affected property.

Notice: Originally, the ConfigurationChange event mechanism was meant to be used by a GUI implementation, which is on the To-Do list. Hence, even though the mechanism is fully operational, it is not yet being used by the Logging Framework itself.
