Class GroupAwareJob

java.lang.Object
org.springframework.batch.core.configuration.support.GroupAwareJob
All Implemented Interfaces:
Job
public class GroupAwareJob extends 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. For example, the source job might be overnightJob and the group might be 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.
