flag allow-no

Mode: Configuration Mode

Description:

Flag allow-no is only used with conjuction with a toggle type attribute. The allow-no flag generates both the normal form and the negated form (no-) of the attribute.

Setting either toggle state of the attribute clears any previous settings of the attribute.

It is important to note that this flag is meaningless if the attribute name is in the negated form.

Example 1:

        object newbie {
            help "Newbie settings";

            /* default is that newbie is not rich */
            attribute no-money {
                help "Is newbie rich?";
                flag allow-no;
                type toggle;
            }

            /* default is that newbie is happy */
            attribute happy {
                help "Is newbie happy?";
                flag allow-no;
                type toggle;
            }
        }
