All Known Implementing Classes:
    LoggingJobHistoryPlugin, LoggingTriggerHistoryPlugin, JobInitializationPluginMultiple, JobInitializationPlugin, SchedulerPluginWithUserTransactionSupport, ShutdownHookPlugin

Provides an interface for a class to become a "plugin" to Quartz.

Plugins can do virtually anything you wish, though the most interesting ones will obviously interact with the scheduler in some way - either actively: by invoking actions on the scheduler, or passively: by being a JobListener, TriggerListener, and/or SchedulerListener.

If you use org.quartz.impl.StdSchedulerFactory to initialize your Scheduler, it can also create and initialize your plugins - look at the configuration docs for details.

If you need direct access your plugin, you can have it explicitly put a reference to itself in the Scheduler's SchedulerContext as part of its #initialize(String, Scheduler) method.

 public  void initialize(String name,
    Scheduler scheduler) throws SchedulerException

Called during creation of the Scheduler in order to give
the SchedulerPlugin a chance to initialize.



At this point, the Scheduler's JobStore is not yet
initialized.



If you need direct access your plugin, for example during Job
execution, you can have this method explicitly put a
reference to this plugin in the Scheduler's
SchedulerContext.

 public  void shutdown()

Called in order to inform the SchedulerPlugin that it
should free up all of it's resources because the scheduler is shutting
down.

 public  void start()

Called when the associated Scheduler is started, in order
to let the plug-in know it can now make calls into the scheduler if it
needs to.
