Examples of AbstractNullPolicy

org.eclipse.persistence.oxm.mappings.nullpolicy.AbstractNullPolicy

PUBLIC: Description: This node null policy allows for the handling of various representations of null in XML documents.

Null policies have 2 concrete implementations:

NullPolicy (default implementation)
IsSetNullPolicy (keyed off isSet() state of the node)

Unmarshal Flag	Description
isSetPerformedForAbsentNode	This umarshal flag represents whether a set is done for absent nodes only.
isNullRepresentedByEmptyNode	If this unmarshal flag is false for empty nodes we set an empty Object for composite mappings, otherwise we set to null.
isNullRepresentedByXsiNil	If this unmarshal flag is false for xsi:nil nodes we ignore the xsi:nil attribute and treat as an empty node. Otherwise we set to null.

Marshal Enum	XMLNullRepresentationType Description
XSI_NIL	Nillable: Write out an xsi:nil="true" attribute.
ABSENT_NODE(default)	Optional: Write out no node.
EMPTY_NODE	Required: Write out an empty or node="" node.

Usage:
