Class FixedNotificationFilter

java.lang.Object
  extended by org.apache.tomcat.util.modeler.FixedNotificationFilter
All Implemented Interfaces:
java.io.Serializable, javax.management.NotificationFilter

public class FixedNotificationFilter
extends java.lang.Object
implements javax.management.NotificationFilter

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.
