Class JobEntityListener

java.lang.Object
com.netflix.genie.web.data.services.impl.jpa.listeners.JobEntityListener
public class JobEntityListener extends Object
Listener for Job JPA entity (JobEntity). Currently tracks persistent changes to the status of a job and notifies an observer. Could be extended to do proxy more persist changes.

N.B. Spring configuration. - This class does not appear in any AutoConfiguration as bean. It is referenced as EventListener by JobEntity. EntityManager creates it even if a bean of the same type exists already. - The constructor parameter persistedJobStatusObserver is marked Nullable so that an instance can be created even if no bean of that type is configured.

Since:
4.0.0
