具有静态成员的类 vs 单例 [英] Class with static members vs singleton

问题描述

只有静态成员的类不就是一种单例设计模式吗?有这样的课有什么坏处吗?详细的解释会有所帮助.

Isn’t a class with only static members a kind of singleton design pattern? Is there any disadvantage of having such a class? A detailed explanation would help.

推荐答案

这种类被称为 monostate - 它与单例有些不同.

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

为什么使用单态而不是单态?在他们的 原始论文中 关于模式，贝尔 &克劳福德提出了三个理由(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
• 单身人士没有名字
• 更容易继承

我必须承认，我不觉得这些特别引人注目.另一方面，单态绝对不比单态更糟.

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.
