FetchGroup implementation

[Craig L Russell]

The JDO expert group has adopted a user-level API for configuring FetchGroups at runtime. There is a factory for FetchGroup in the PersistenceManager and PersistenceManagerFactory, corresponding to EntityManager and EntityManagerFactory.

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

I'd like to implement this concept for OpenJPA, and have a few questions before I start. Currently there is an Annotation org.apache.openjpa.persistence.FetchGroup that allows an annotation to be defined for a class or field. There are also FetchPlan.java and FetchPlanImpl.java in that same package. The FetchPlan is the interface (not standard) and the FetchPlanImpl is the implementation for the FetchPlan interface. So if we want to have an interface representing the FetchGroup how do we avoid the name conflict between the annotation name and the interface name for FetchGroup?
