Description copied from interface: Scheduler

Delete the identified Jobs from the Scheduler - and any associated Triggers.

Specified by:

deleteJobs in interface Scheduler

Returns:

true if all of the Jobs were found and deleted, false if one or more were not deleted.

If any of the given jobs or triggers already exist (or more specifically, if the keys are not unique) and the replace parameter is not set to true then an exception will be thrown.

Specified by:

If the related job does not have any other triggers, and the job is not durable, then the job will also be deleted.

Note that while this bulk operation is likely more efficient than invoking unscheduleJob(TriggerKey triggerKey) several times, it may have the adverse affect of holding data locks for a single long duration of time (rather than lots of small durations of time).

interrupt

public boolean interrupt(JobKey jobKey)
                  throws UnableToInterruptJobException

Description copied from interface: Scheduler

Request the interruption, within this Scheduler instance, of all currently executing instances of the identified Job, which must be an implementor of the InterruptableJob interface.

If more than one instance of the identified job is currently executing, the InterruptableJob#interrupt() method will be called on each instance. However, there is a limitation that in the case that interrupt() on one instances throws an exception, all remaining instances (that have not yet been interrupted) will not have their interrupt() method called.

If you wish to interrupt a specific instance of a job (when more than one is executing) you can do so by calling Scheduler.getCurrentlyExecutingJobs() to obtain a handle to the job instance, and then invoke interrupt() on it yourself.

This method is not cluster aware. That is, it will only interrupt instances of the identified InterruptableJob currently executing in this Scheduler instance, not across the entire cluster.

Specified by:

interrupt in interface Scheduler

Returns:

true is at least one instance of the identified job was found and interrupted.

Throws:

UnableToInterruptJobException - if the job does not implement InterruptableJob, or there is an exception while interrupting the job.

See Also:

InterruptableJob.interrupt(), Scheduler.getCurrentlyExecutingJobs()
