 String coreName)

shutdown

public void shutdown()
              throws org.quartz.SchedulerException

Throws:

 Collection<Tracker> trackers)

Throws:

org.quartz.SchedulerException

deleteJobForTrackerInstance

public void deleteJobForTrackerInstance(String coreName,
 Tracker tracker)

Delete a Tracker Job ONLY if its exactly the same tracker instance that was passed in. In theory more than one instance of a core can exist with the same core name but the scheduler stores jobs using the core name as a unique key (even though it may not be unique). This method gets the tracker instance associated with the Job and compares to see if its identical to the instance that is passed in. If they are identical then the job is deleted. Otherwise, another core (of the same name) scheduled this job, so its left alone.

Parameters:

coreName - the core name.

tracker - Specific instance of a tracker

 Tracker tracker)
