你可以解释上下文设计模式吗？ [英] Can you explain the Context design pattern?

问题描述

我已经开始阅读上下文设计模式。这是我从文本中理解的：

• 你有一个包含所有变量的地图




• 你将它传递给需要它的人，所以你不必发送所有变量作为方法参数

我是否得到？

解决方案

然而，我也认为这是更多的避免反模式。了解为什么此处。

I've started to read about the Context design pattern. Here's what I understood from the text :

• you have a map containing all your variables

• you pass it around to whoever needs it, so that you won't have to send all the variables as method parameters

Did I "get" it?

解决方案

I think you got it.

However, I also think it is more of an anti-pattern to be avoided. See why here.
