Quartz provides an interface (
ISchedulerPlugin) for plugging-in additional functionality.
Plugins that ship with Quartz to provide various utility capabilities can be found documented in the
Quartz.Plugins namespace. They provide functionality such as auto-scheduling of jobs upon scheduler startup, logging a history of job and trigger events, and ensuring that the scheduler shuts down cleanly when the virtual machine exits.
When a trigger fires, the Job it is associated to is instantiated via the JobFactory configured on the Scheduler. The default JobFactory simply activates a new instance of the job class. You may want to create your own implementation of JobFactory to accomplish things such as having your application's IoC or DI container produce/initialize the job instance.
IJobFactory interface, and the associated
IScheduler.JobFactory setter property.
Since Quartz 3.1, there's built-in support for integrating with Microsoft Dependency Injection which in turn allows to use different IoC container implementations.
Quartz also provides a number of utility Jobs that you can use in your application for doing things like sending e-mails and invoking remote objects. These out-of-the-box Jobs can be found documented in the
Quartz.Jobs namespace and are part of the Quartz.Jobs NuGet package.
