Examples of org.quartz.Trigger

org.quartz.Trigger

The base abstract class to be extended by all Triggers.

Triggers s have a name and group associated with them, which should uniquely identify them within a single {@link Scheduler}.

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

Triggers can 'send' parameters/data to Jobs by placing contents into the JobDataMap on the Trigger.
