If you do not know for sure whether the value is of type UndefinedType, you should check the isNull() methods afterwards before calling any methods on the returned value. Returns: The value converted to an Undefined Definition at line 336 of file value.cpp. References KJS::Value::isNull(), and KJS::Value::type().
