java.lang.Objectorg.jibx.extras.IdRefMapperBase
public abstract class IdRefMapperBase
Abstract base custom marshaller/unmarshaller for an object reference. This
marshals the reference as an empty element with a single IDREF attribute, and
unmarshals an element with the same structure to create a reference to the
object with that ID value. To use this class you need to create a subclass
with a constructor using the same signature as the one provided (calling the
base class constructor from your subclass constructor) and implement the
abstract getIdValue(java.lang.Object) method in your subclass. You can also override
the provided getAttributeName() method to change the name used for the
IDREF attribute. Note that this class can only be used when the definitions
precede the references in the XML document; if a referenced ID is not defined
the unmarshaller throws an exception.
