Subject [jira] Created: (JDO-469) Delete by object id
Date Tue, 06 Mar 2007 19:25:24 GMT
Delete by object id
-------------------

                 Key: JDO-469
                 URL: https://issues.apache.org/jira/browse/JDO-469
             Project: JDO
          Issue Type: Improvement
          Components: api2, api2-legacy, specification
    Affects Versions: JDO 2 maintenance release 1
            Reporter: Matthew T. Adams
             Fix For: JDO 2 maintenance release 1


Currently, Query & PersistenceManager allow a user to get by query and by object id, respectively.
 However, symmetry is broken in the case of deletion:  you can delete by query, but you cannot
delete by object id.  The result is that you are forced to use a query or load each object
that you want to delete.  I noticed this asymmetry when I came across a use case where I had
the object id and wanted to delete by id without having to load the object or construct a
query.

Why don't the following PersistenceManager methods exist?

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

Can we add these?
