schedule

public void schedule(Tracker tracker,
                     java.lang.String coreName,
                     java.util.Properties props)

Schedules individual trackers based on the solrcore properties.

Parameters:

tracker - the tracker to bo scheduled.

coreName - the owning core name.

props - the core properties.

getJobName

protected java.lang.String getJobName(Tracker tracker,
                                      java.lang.String coreName)

shutdown

public void shutdown()
              throws org.quartz.SchedulerException

Throws:

org.quartz.SchedulerException

deleteTrackerJobs

public void deleteTrackerJobs(java.lang.String coreName,
                              java.util.Collection<Tracker> trackers)
                       throws org.quartz.SchedulerException

Throws:

org.quartz.SchedulerException

deleteJobForTrackerInstance

public void deleteJobForTrackerInstance(java.lang.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

deleteTrackerJob

public void deleteTrackerJob(java.lang.String coreName,
                             Tracker tracker)
