Examples of javax.jdo.PersistenceManager.detachCopy()

javax.jdo.PersistenceManager.detachCopy()
Detach the specified instance from the PersistenceManager. The flags for detachment (DETACH_LOAD_FIELDS and DETACH_UNLOAD_FIELDS) and the active fetch groups determine the scope of fetching for the graph of instances reachable from the pc parameter.
