Class ERQSJobSupervisor

java.lang.Object

er.quartzscheduler.foundation.ERQSAbstractJob

er.quartzscheduler.foundation.ERQSJobSupervisor

All Implemented Interfaces:

org.quartz.Job

@DisallowConcurrentExecution
public class ERQSJobSupervisor
extends ERQSAbstractJob

The supervisor has in charge to add, remove or update the list of job handled by the quartz scheduler.

Every job handled by the supervisor has a group starting by GROUP_NAME_PREFIX. The goal is to let developers to add any job directly, aka not linked to a job description. For that reason, by convention, the jobs not handled by the supervisor must have a group not starting with GROUP_NAME_PREFIX
