CAppJobEventTranslator Standard Listener that generates notification events.

IAppJobListener Interface for components that need to be notified about changes in Jobs.

CAppJobNotification Notification send by CAppJobEventTranslator.

CEvent - generic event implementation TODO TODO - Attachments.

IAppJobEngineListener - receives notifications about changes in job state.
