Class GroupAwareJob

  • All Implemented Interfaces:
    Job
    public class GroupAwareJob
extends java.lang.Object
implements Job
    A Job that can optionally prepend a group name to another job's name, to make it fit a naming convention for type or origin. E.g. the source job might be overnightJob and the group financeDepartment, which would result in a Job with identical functionality but named financeDepartment.overnightJob . The use of a "." separator for elements is deliberate, since it is a "safe" character in a URL.
