Difference between DeleteJob() and Unschedulejob() in Quartz 1.8.5

Question

Can someone let me know the difference between deleteJob() and unscheduleJob() of quartz 1.8.5?

Thanks.

Answer 1

If you look at the implementations of both methods in QuartzScheduler.java , you'll notice that deleteJob(JobKey jobKey)

• loops through all the triggers having a reference to this job, to unschedule them
• removes the job from the jobstore

whereas unscheduleJob(TriggerKey triggerKey) just unschedules a trigger, so if other triggers reference this job, they won't be changed.
