public class VariableOneToOneAccessor
extends ObjectAccessor

INTERNAL: A variable one to one relationship accessor. A VariableOneToOne annotation currently is not required to be defined on the accessible object, that is, a v1-1 can default if the raw class is an interface. 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.

EclipseLink 1.0
