Hi James,
I don't remember reading about any such API in OpenJpa (some body
please correct me if there is one), but getting that information should not be
that difficult. I just wrote a little API which would get you the information,
if the property has been loaded or not. Based on my really simple tests, the
API works fine. If you want you can use it for your tests.
public static boolean isPropertyLoaded(Object entity, String property) {
PersistenceCapable pc = (PersistenceCapable) entity;
StateManagerImpl sm = (StateManagerImpl) pc.pcGetStateManager();
ClassMetaData metaData = sm.getMetaData();
FieldMetaData[] fields = metaData.getFields();
int dx = 0;
for (int j = 0; j < fields.length; j++) {
if (fields[j].getName().equals(property)) {
dx = j;
break;
}
}
return sm.getLoaded().get(dx);
}
For forcing initialization you can just call the getter method. I am sure there
are better ways of getting the same information, but this is based on my very
limited knowledge of OpenJPA.
Thanks and Regards,
Nitish Kumar

Subject: hibernate conversion items
In unit tests (technically integration tests) where I test my mappings, I
used to call (in hibernate)
Hibernate.isInitialized(someentity.property) to validate things were lazy or
to generally check their load status. Also, Hibernate had
Hibernate.initialize(sometntity.property) to programmatically force
initialization. Is there an easy way to do this in openjpa.? I see the
fetchgroups (which are nice), but configuring a fetchgroup seems overkill in
some cases...
Can someone point me to equivalent items in openjpa?
Thanks!
James
