      • createPrimaryKeyFromId

        public Object createPrimaryKeyFromId​(Object key,
                                     AbstractSession session)
        Description copied from class: CMP3Policy
        INTERNAL: Use the key to create a EclipseLink primary key. If the key is simple (direct mapped) then just add it to a vector, otherwise must go through the inefficient process of copying the key into the bean and extracting the key from the bean.
        Overrides:
        createPrimaryKeyFromId in class CMP3Policy

      • initializePrimaryKeyFields

        protected CMPPolicy.KeyElementAccessor[] initializePrimaryKeyFields​(Class<?> keyClass,
                                                                    AbstractSession session)
        Description copied from class: CMP3Policy
        INTERNAL: Cache the bean's primary key fields so speed up creating of primary key objects and initialization of beans. Note, we have to re-look up the fields for the bean class since these fields may have been loaded with the wrong loader (thank you Kirk). If the key is compound, we also have to look up the fields for the key.

        initializePrimaryKeyFields in class CMP3Policy
