[Tom Ware <tom.ware@xxxxxxxxxx>]

Hi Andreas,

  The best suggestion I can think of is to write a similar method.  You can leverage the behavior already provided by persistenceUnitUtil.isLoaded(value).  In addition to that, you can do your own check for null.  The additional code you will have to add is EclispeLink specific.  Essentially what you need to do is check whether EclispeLink thinks the class of the object is one that is an Entity. You can do that using our org.eclipse.persistence.jpa.JpaHelper utility.  It provides a set of method that allow you to get at the EclipseLink internals from a JPA class.  One thing you could do is this:

  Session session = JpaHelper.getDatabaseSession(entityManagerFactory);
  if (session.getClassDescriptor(object.getClass()) != null){
      // this indicates this is an Entity/MappedSuperclass//Embeddable

I'm looking for an equivalent of Hibernate.isInitialized(object) which checks if the passed object is "initialized".

 

- If object is null, it returns true.

- If the object is an Entity and the entity is loaded it returns true.

- If the object is something other than null or an Entity (String, Collection, @ManyToOne or whatever) it returns true unless the object is a lazy-mapped attribute with isn't loaded yet.

 

I'ved tried to use persistenceUnitUtil.isLoaded(value) but it fails if the value is null or not an Entity....

 

Thanks.
