If the value's type is not UndefinedType, a null object will be returned (i.e. one with it's internal pointer set to 0). If you do not know for sure whether the value is of type UndefinedType, you should check the isValid() methods afterwards before calling any methods on the returned value.

Returns:
The value converted to an Undefined
