Examples of javax.jdo.PersistenceManager.detachCopyAll()

javax.jdo.PersistenceManager.detachCopyAll()
Detach the specified instances 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 pcs parameter. The state of fields in the affected instances is as specified by the FetchPlan. @param pcs the instances to detach @return the detached instances @see #detachCopyAll(Object[]) @since 2.0
