public class DerivedIdClassAccessor
extends EmbeddedAccessor

A derived id class accessor is found within an entity's embedded id class and is a reference back to a parents id class. Key notes: - any metadata mapped from XML to this class must be compared in the equals method. - any metadata mapped from XML to this class must be handled in the merge method. (merging is done at the accessor/mapping level) - any metadata mapped from XML to this class must be initialized in the initXMLObject method. - methods should be preserved in alphabetical order.
