静态类和单例 [英] static class and singleton

问题描述

不是所有静态成员/方法的类都是一种单例设计模式？有没有什么缺点，特别是有这样的类？详细的解释将有所帮助。

Isn't a class with all static members/methods a kind of singleton design pattern? Is there any disadvantage in particular of having such classes? A detailed explanation would help.

推荐答案

这种类被称为 monostate - 它与单身人士有所不同。

This kind of class is known as a monostate - it is somewhat different from a singleton.

为什么使用单体而不是单身？在他们的原始论文在模式上，贝尔&克劳福德提出三个理由（由我解释）：

Why use a monostate rather than a singleton? In their original paper on the pattern, Bell & Crawford suggest three reasonns (paraphrased by me):

• 更自然的访问语法


• singleton缺少


• 更容易继承自

我必须承认，我没有找到任何这些特别引人注目。另一方面，单身人士绝对不会比单身人士更糟糕。

I must admit, I don't find any of these particularly compelling. On the other hand, the monostate is definitely no worse than the singleton.
