monitored - an absolute path is recommended.public static final String DIRECTORY_SCAN_LISTENER_NAME
JobDataMap key with which to specify the
DirectoryScanListener to be
notified when the directory contents change.public static final String MINIMUM_UPDATE_AGE
JobDataMap key with which to specify a long
value that represents the minimum number of milliseconds that must have
past since the file's last modified time in order to consider the file
new/altered. This is necessary because another process may still be
in the middle of writing to the file when the scan occurs, and the
file may therefore not yet be ready for processing.
If this parameter is not specified, a default value of
5000 (five seconds) will be used.

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 that are watching the job's
execution.
