 com.bigbross.bossa.notify.NotificationBus
| NotificationBus | | public class NotificationBus implements Serializable(Code) | | This class manages all event notifications inside Bossa. The events are
notified to listeners registered in the bus. This registration can happen
either at the bus creation or at a later time.
The listeners registered after the bus is created will not be preserved
if this bus is serialized. Due to this behaviour, objects outside the Bossa
core that are registered as listeners may lose notification of events if
a failure crashes the system.
