public abstract class AbstractNullPolicy extends Object
Null policies have 2 concrete implementations:
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 |

getIsSetPerformedForAbsentNode() |
XMLNullRepresentationType |
getMarshalNullRepresentation()
Get the enum that determines what XML to write when a null value is encountered.
|
boolean |
isNullRepresentedByEmptyNode() |
boolean |
isNullRepresentedByXsiNil() |
void |
setMarshalNullRepresentation(XMLNullRepresentationType anEnumInstance)
Set the enum that determines what XML to write when a null value is encountered.

abstract void |
xPathNode(org.eclipse.persistence.internal.oxm.XPathNode xPathNode,

INTERNAL: When using the SAX Platform this allows a NodeValue to be
registered to receive events from the TreeObjectBuilder.
