JobChainingJobListener (Quartz Enterprise Job Scheduler 2.5.1 API)

java.lang.Object
- org.quartz.listeners.JobListenerSupport
- - org.quartz.listeners.JobChainingJobListener

All Implemented Interfaces:

JobListener
```
public class JobChainingJobListener
extends JobListenerSupport
```
Keeps a collection of mappings of which Job to trigger after the completion of a given job. If this listener is notified of a job completing that has a mapping, then it will then attempt to trigger the follow-up job. This achieves "job chaining", or a "poor man's workflow".
Generally an instance of this listener would be registered as a global job listener, rather than being registered directly to a given job.

If for some reason there is a failure creating the trigger for the follow-up job (which would generally only be caused by a rare serious failure in the system, or the non-existence of the follow-up job), an error message is logged, but no other action is taken. If you need more rigorous handling of the error, consider scheduling the triggering of the flow-up job within your job itself.
