Investigate pm.getXXX methods that don't take a Class arg #164

Closed GoogleCodeExporter closed 8 years ago

pm.getObjectbyId() and pm.getObjectsById()

Can we make these work?

JDO operates the same as it should with those methods.
tx.begin();
pm.makePersistent(myObj);
tx.commit();
Object id = pm.getObjectId(myObj);
...
tx.begin();
MyClass myObj = (MyClass)pm.getObjectById(id);

See the foot of JDOFetchTest for a simple test of this. The "id" passed in is a 
JDO identity, not your internal datastore identity (and nor should it be your 
identity to be JDO compliant)
