    public class FOPEventListenerProxy
    extends java.lang.Object
    implements EventListener

For layout events, it reduces the default severity level if FOP signals that it can recover from the event.

      • processEvent

        public void processEvent​(Event event)
        This method is called for each event that is generated. With the event's ID it is possible to react to certain events. Events can also simply be recorded and presented to a user. It is possible to throw an (unchecked) exception if the processing needs to be aborted because some special event occurred. This way the client can configure the behaviour of the observed application.
