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
