All Implemented Interfaces:

Runnable, ArooaContextAware, Forceable, PropertyChangeNotifier, Iconic, LogEnabled, Resetable, StateListener, Stateful, Stoppable

public class DependsJob
extends SimpleJob
implements Stoppable, StateListener

Description

A job which depends on another job.

• If the other job is in a READY state, this job will run the other job.
• If the other job is in an EXECUTING state, this job will wait.
• If the other job has finished this job will reflect the completion state.

This job is intended to simulate Ant's dependency like functionality however it's usefulness is currently questionable. Solutions using Trigger may well be more elegant.
