public PersistenceManager getPersistenceManager (); public PersistenceManager getPersistenceManager (String user, String pass);
The PersistenceManagerFactory
interface
includes two getPersistenceManager
methods
for obtaining PersistenceManager
instances.
One version takes as parameters the user name and password to
use for the PersistenceManager
's data
store connection. The other version relies on the
ConnectionUserName
and
ConnectionPassword
settings of the
PersistenceManagerFactory
. Both methods
may return a newly-constructed
PersistenceManager
, or may return
one from a pool of instances.
If the PersistenceManagerFactory
was not already
immutable, then it will be after you acquire the first
PersistenceManager
from it.
Any attempt to change the factory's properties will result in a
JDOUserException
.
