Method Detail

newInstance

ProxyCollection newInstance(Class elementType,
                            Comparator compare,
                            boolean trackChanges,
                            OpenJPAConfiguration conf)

This method should return a new proxy of the same concrete type as the implementing class. Used by the ProxyManager factories: one template instance of each type is created for the purpose of producing new instances via this method. Overcomes the performance penalties of reflection.
