public class FixedNotificationFilter
Special NotificationFilter that allows modeler to optimize its notifications.
This class is immutable - after you construct it it'll filter based on
a fixed set of notification names.
The JMX specification requires the filters to be called before the
notifications are sent. We can call this filter well in advance, when
the listener is added. Based on the result we can maintain separate
channels for each notification - and reduce the overhead.
