學過物件導向程式設計的人,都知道繼承(inheritance)與複合(composition)這兩種觀念。前者是「is a」,後者則是「has a」的關係。近年來很多人提倡「favor composition over inheritance」,我也是支持者之一,但為何這樣,三言兩語又很難講清楚。我只能說,以前維護Java程式碼的時候,那一層又一層的繼承關係讓人腦袋發脹...

这里重点讨论一下composition over inheritance的思想和jdk本身设计中的几个反例。希望通过这些分析能够有一个更深刻的理解而不至于浮于表面。 概念及对比 关于composition以及inheritance的概念其实再简单不过了。我们在创建的某个类中包含对其他类的引用,在实现某些功能的时候实际上是利用到了被引用类的一些方法或者功能。

Favor Composition Over Inheritance 项目 2012/09/05 Making code reusable through public class inheritance (PCI) is so convenient and easy that to say it should be avoided may sound a bit heretical. After all, isn’t this what OOP is about? And yet that’s the position I hold. To be ...
In my view, the real benefit of Composition over Inheritance is that it encourages better problem decomposition –if you don’t break up the problem into smaller pieces (that are easier to tackle) first you have nothing to compose with later on. Scott Wlaschin’s railway oriented programming...
