当要使用的设计模式？ [英] When to use which design pattern?

问题描述

我喜欢设计模式非常多，但我觉得很难看的时候我可以申请之一。我看过很多网站，其中设计模式进行了说明。我明白了其中大部分，但我觉得很难承认我自己的情况的模式。

I like design patterns very much, but I find it difficult to see when I can apply one. I have read a lot of websites where design patterns are explained. I do understand the most of them, but I find it difficult to recognize a pattern in my own situations.

所以，这就是为什么我问这个问题。是否有任何指引/警钟时使用的设计模式。

So, that is why I ask this question. Are there any guidelines / alarm bells when to use which design pattern.

例如，如果你正在做一个switch语句来确定哪些对象需要创建，你可能要使用的工厂设计模式。因此，在这种情况下，switch语句是一个警钟使用工厂模式。

For example, if you are doing a switch statement to determine which object you need to create, you probably want to use the factory design pattern. So the switch statement in this case is a 'alarm bell' to use the Factory pattern.

那么，你知道更多'警钟'，以确定一个设计模式？

So, do you know more 'alarm bells' to determine a design pattern?

推荐答案

对于初学者只是采取偷看在这个页面：

While Jeremy here deals with a few set of patterns, you must read these articles and then follow it up with this: http://codebetter.com/jeremymiller/2005/09/01/learning-about-design-patterns/

此外，使用此文章（尤其是埃里克·伽马的采访）的引用，你应该设置。

Also use the references on this article(especially Eric Gamma's interview) and you should be set.
