All Implemented Interfaces:

Job, StatefulJob

public class FileScanJob
extends java.lang.Object
implements StatefulJob

execute

public void execute(JobExecutionContext context)
             throws JobExecutionException

Description copied from interface: Job

Called by the Scheduler when a Trigger fires that is associated with the Job.

The implementation may wish to set a result object on the JobExecutionContext before this method exits. The result itself is meaningless to Quartz, but may be informative to JobListeners or TriggerListeners that are watching the job's execution.

Specified by:

execute in interface Job

Throws:

JobExecutionException - if there is an exception while executing the job.

getLastModifiedDate

protected long getLastModifiedDate(java.lang.String fileName)
