List of detachCopy() Examples

Examples of 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. The state of fields in the affected instances is as specified by the FetchPlan. @param pc the instance to detach @return the detached instance @see #detachCopyAll(Object[]) @since 2.0
org.apache.openjpa.persistence.OpenJPAEntityManager.detachCopy()
Detach the specified object from the entity manager, detaching based on the AutoDetach value specified and returning a copy of the detached entity. @param pc the instance to detach @return the detached instance @since 2.0.0Note: This method provides the same contract as the detach method with signature: public T detach(T pc) available in the 1.x release of OpenJPA. The JPA 2.0 specification defined a method with an incompatible signature and different semantics. The specification defined method trumped the existing method.
org.datanucleus.state.StateManager.detachCopy()
Method to make detached copy of this instance @param state State for the detachment process @return the detached PersistenceCapable instance
org.jpox.sco.SCO.detachCopy()
Method to return a detached copy of this object. Detaches all components of this object that are also PersistenceCapable. @param state State of the detachment process @return The detached copy
