Method Summary

Modifier and Type	Method and Description
boolean	isMarshalOnlyNodeValue() INTERNAL: Return whether we ignore this node value when marshalling its parent
boolean	marshal(XPathFragment xPathFragment, MarshalRecord marshalRecord, java.lang.Object object, AbstractSession session, NamespaceResolver namespaceResolver) INTERNAL:
boolean	marshalSingleValue(XPathFragment xPathFragment, MarshalRecord marshalRecord, java.lang.Object object, java.lang.Object objectValue, AbstractSession session, NamespaceResolver namespaceResolver, MarshalContext marshalContext) INTERNAL: This method provides an optimization in cases where the value has already been calculated.
boolean	startElement(XPathFragment xPathFragment, UnmarshalRecord unmarshalRecord, org.xml.sax.Attributes atts) During an unmarshal event we output an empty array for a null value
