Utility derived value allows products or services to be measured on outcome instead of demand or supply theories that have the inherent ability to be manipulated.

Placing an inheritance demand on a static method in the base class has no impact on derived classes because the static methods are unrelated.

由于没有相关的静态方法，因此在基底类别的静态方法上放置继承要求对衍生类别并没有影响。

All methods in the derived class, including the constructor for the class, must meet the inheritance demand.

派生类中的所有方法(包括类的构造函数)都必须满足该继承要求。
