Examples of NullPolicy

org.eclipse.persistence.oxm.mappings.nullpolicy.NullPolicy
ffect
aNullPolicy.setNullRepresentedByEmptyNodeNode(false); // default or no effect
aNullPolicy.setNullRepresentedByXsiNil(false); // default or no effect

Input XML
<employee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <firstname xsi:nil=true/> </employee>
Output Object State
anEmployee.getFirstname() = null anEmployee.isSet(firstname) = true
Marshal null composite object (isSet=true) as empty node: .
Code Sample
XMLDescriptor aDescriptor = new XMLDescriptor(); aDescriptor.setJavaClass(Team.class); aDescriptor.setDefaultRootElement("team"); XMLCompositeObjectMapping aManagerMapping = new XMLCompositeObjectMapping(); aManagerMapping.setAttributeName("manager"); aManagerMapping.setXPath("manager/text()"); // do not modify the default NullPolicy or the 3 boolean flags AbstractNullPolicy aNullPolicy = afirstNameMapping.getNullPolicy(); aDescriptor.addMapping(aManagerMapping); aNullPolicy.setMarshalNullRepresentation(XMLNullRepresentationType.EMPTY_NODE);
Input Object State
aTeam.getManager() = null aTeam.isSet(manager) = no effect
Output XML
<team xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <manager/> </team> @see org.eclipse.persistence.internal.oxm.NullCapableValue @since Oracle TopLink 11g Release 1 (11.1.1)
