getFetchGroup(cls, name) - JDO PersistenceManager's method
Get a modifiable
FetchGroup
for the Class and name. If a modifiable
FetchGroup
already exists in the
PersistenceManager
scope, return it. If not, create and populate a new
FetchGroup
from the existing definition in the
PersistenceManager
or
PersistenceManagerFactory
. If the definition for the
FetchGroup
is not in scope in either the
PersistenceManager
or
PersistenceManagerFactory
, create it with no members. The
FetchGroup
immediately becomes active and in scope of the PersistenceManager, and hides the corresponding fetch group in the PersistenceManagerFactory.
