影响代码的可维护性的因素有很多,比如: Code Review(代码审查)是个很好的测验代码可读性的方法。 如果你的同事可以轻松读懂你写的代码,说明你的代码可读性很好; 如果其他人在读你的代码时,有很多疑问,说明你的代码可读性并不高。 2.3 可扩展性(extensibility) 可扩展性表示代码应对未来需求变化的能力。 如果原有...
Design Patterns 之原型模式 原型(Prototype)模式的定义如下:用一个已经创建的实例作为原型,通过复制该原型对象来创建一个和原型相同或相似的新对象。在这里,原型实例指定了要创建的对象的种类。用这种方式创建对象非常高效,根本无须知道对象创建的细节。例如,Windows操作系统的安装通常较耗时,如果复制就快了很多。在生活...

概述 不使用建造者模式 建造者模式(Builder) 连贯接口 Fluent Builder 本文主要会介绍设计模式中的建造者模式(Builer)。通过列举几个例子,来帮助大家更好的理解这个模式。 概述 我们为什么在写代码的过程中需要使用建造者模式这种方法呢?对于有些对象来说,他们比较简单,因此一个简单的构造函数就可以完成对于对象的生成...

I think the problem with patterns is that often people do know them but don't know when to apply which. Remember that each pattern has its own trade-offs. And you need to pay attention more to why you're choosing a certain pattern than to how to implement it....
The first time I heard the word “prototype” was inDesign Patterns. Today, it seems like everyone is saying it, but it turns out they aren’t talking about thedesign pattern. We’ll cover that here, but I’ll also show you other, more interesting places where the term “prototype” ...
