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 ob
ject 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 i
s that you are forced to us
e a query or load each object that you want to delete.  I noticed this asymm
etry when I came across a use case where I had the object id and wanted to d
elete 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?
