Class 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

    NullCapableValue
