All Implemented Interfaces:

Serializable, Runnable, ArooaContextAware, ArooaSessionAware, Forceable, PropertyChangeNotifier, Iconic, LogEnabled, Resetable, Stateful, Stoppable

public class StopJob
extends SerializableJob
implements Stoppable

Description

A job which stops another job.

Normally The stop job will not complete until the job it is stopping is in a not executing state. Therefore if the stop job is attempting to stop a parent job of itself the stop job could block indefinitely. This case is detected and the job enters an Exception state.

Example

Examples elsewhere.

• JMXClientJob has an example where the stop job is used to stop a client once the connection is no longer needed.
