EclipseLink/JPA EntityListener: Check if entity is modified -

-

i'm using default entitylisteners (preupdate , prepersist) write create , update timestamps entities. when new child added collection (onetomany) , persist called parent record send entitylistener , timestamps updated. problem don't want update parent if new child record added collection. there way check if entity modified (inside entitylisterner)? andreas

this might (not tested, think work). event descriptorevent got, object entity want check changes.

   unitofworkimpl uow = (unitofworkimpl) event.getsession();    classdescriptor descriptor = uow.getdescriptor(object);     boolean isnew = uow.isobjectnew(object);         if (isnew || descriptor.getobjectchangepolicy().shouldcompareexistingobjectforchange(object, uow, descriptor)) {             objectchangeset changes = null;             if (isnew) {                 changes = descriptor.getobjectchangepolicy().calculatechangesfornewobject(object, changeset, uow, descriptor, true);             } else {                 changes = descriptor.getobjectchangepolicy().calculatechangesforexistingobject(object, changeset, uow, descriptor, true);             }    boolean haschanges = changes.haschanges();
