Class IsSetNullPolicy

java.lang.Object

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

org.eclipse.persistence.oxm.mappings.nullpolicy.IsSetNullPolicy

public class IsSetNullPolicy
extends AbstractNullPolicy

PUBLIC: Description: This null policy allows for various configurations of isSet behavior to be set.
Marshal:
The boolean value of the isSet() state of a node will determine whether a node will be written out for a null value. Unmarshal:

The following instance fields can be set:

• isSetMethodName:
• isSetParameterTypes:
• isSetParameters:

Usage:

• Set to a non-null value

IsSet==true, value=value
• Not set

isSet=false, value=null
• Set to null value

isSet=true, value=null
• Set to default value

isSet=false, value=default

Since:

Oracle TopLink 11g Release 1 (11.1.1)
