Package org.apache.nifi.bootstrap.notification

Interface NotificationService

All Superinterfaces:

ConfigurableComponent

All Known Implementing Classes:

AbstractNotificationService, EmailNotificationService, HttpNotificationService

public interface NotificationService
extends ConfigurableComponent

A NotificationService is simple mechanism that the Bootstrap can use to notify interested parties when some event takes place, such as NiFi being started, stopped, or restarted because the process died.

Note: This feature was introduced in version 0.3.0 of NiFi and is likely to undergo significant refactorings. As such, at this time it is NOT considered a public API and may well change from version to version until the API has stabilized. At that point, it will become a public API.

Since:

0.3.0
