Class JobRunShell

java.lang.Object
  org.quartz.listeners.SchedulerListenerSupport
      org.quartz.core.JobRunShell

All Implemented Interfaces:

java.lang.Runnable, SchedulerListener

Direct Known Subclasses:

JTAJobRunShell

public class JobRunShell
extends SchedulerListenerSupport
implements java.lang.Runnable

JobRunShell instances are responsible for providing the 'safe' environment for Job s to run in, and for performing all of the work of executing the Job, catching ANY thrown exceptions, updating the Trigger with the Job's completion code, etc.

A JobRunShell instance is created by a JobRunShellFactory on behalf of the QuartzSchedulerThread which then runs the shell in a thread from the configured ThreadPool when the scheduler determines that a Job has been triggered.
