oop - 为什么工厂方法是类模式，而抽象工厂是对象模式？

Question

来自 GOF 的书:

Class patterns deal with relationships between classes and their subclasses. These relationships are established through inheritance, so they are static-fixed at compile-time. Object patterns deal with object relationships, which can be changed at run-time and are more dynamic. Almost all patterns use inheritance to some extent. So the only patterns labeled "class patterns" are those that focus on class relationships.

为什么工厂方法是类模式，抽象工厂是对象模式，因为它们看起来非常相似？

谢谢。

工厂模式可能更适合放在它自己的类别中。但是对象/类划分背后的逻辑可能很简单。工厂方法的最小形式是静态的(不可配置)，就像类一样。但是抽象工厂结果(它们产生的对象)类依赖于一些输入数据，并且由于它是动态效果，因此应该放入对象模式类别。
