[Craig L Russell]

Please vote for

[ ] Proposal A void deleteObjectById
[ ] Proposal B long deleteObjectById
[ ] Proposal C (do nothing)

This vote will close Monday 12-Mar-2007.

Please see https://issues.apache.org/jira/browse/JDO-469

I'd like to discuss adding the methods to PersistenceManager:



Proposal A

proposed by Matthew Adams:
void deleteObjectById(Class cls, Object key);
void deleteObjectById(Object oid);
void deleteObjectsById(Collection oids);
void deleteObjectsById(Object[] oids);



Proposal B


long deleteObjectById(Class cls, Object key);
long deleteObjectById(Object oid);
long deleteObjectsById(Collection oids);
long deleteObjectsById(Object[ ] oids);

Proposal C

do nothing

P.S. A good JDO? O, Gasp!

Both Proposals A and B follow the basic rules of deletePersistent, with differences if the object identified by the oid is not persistent. With proposal A, any object that cannot be deleted would throw an exception similar to what is done with deletePersistent. I think we might want to allow for the possibility that it was not possible to delete all the requested items, so add a return value with the number of objects actually deleted:
