org.quartz Interface JobDetail

All Superinterfaces:
Cloneable, Serializable
All Known Subinterfaces:
LocalityJobDetail
All Known Implementing Classes:
DelegatingLocalityJobDetail, JobDetailImpl
public interface JobDetail
extends Serializable, Cloneable

Conveys the detail properties of a given Job instance. JobDetails are to be created/defined with JobBuilder.

Quartz does not store an actual instance of a Job class, but instead allows you to define an instance of one, through the use of a JobDetail.

Jobs have a name and group associated with them, which should uniquely identify them within a single Scheduler.

Triggers are the 'mechanism' by which Jobs are scheduled. Many Triggers can point to the same Job, but a single Trigger can only point to one Job.
