- Scheduler
The Primary API for scheduling, unscheduling, adding, and removing Jobs.
- Job
The interface to be implemented by classes that represent a ‘job’ in Quartz. It has a single method called execute() where you write the work that needs to be performed by the Job.
- JobDetail
A JobDetail represents an instance of a Job. It also contains additional data in the form of a JobDataMap that is passed to the Job when it is executed.
Every JobDetail is identified by a JobKey that consists of a name and a group. The name must be unique within a group.
- Trigger
A Trigger, as the name suggests, defines the schedule at which a given Job will be executed. A Job can have many Triggers, but a Trigger can only be associated with one Job.
Every Trigger is identified by a TriggerKey that comprises of a name and a group. The name must be unique within a group.
Just like JobDetails, Triggers can also send parameters/data to the Job.
- JobBuilder
JobBuilder is a fluent builder-style API to construct JobDetail instances.
- TriggerBuilder
TriggerBuilder is used to instantiate Triggers.
