不是说 iterator 或者 visitor 必须使用 inheritance 或者 aggregation,两种都是可以的。简单的小节就是 composite 提供了一种数据组织形式,iterator 提供遍历这种结构或者容器等类似对象的通用方案,visitor 是 algorithm 作用在一个复杂对象各个元素上的一种钩子。iterator 和 visitor 对处理的复杂对象都有足够的了解,能够...
Simple Inheritance Example in VB.NetHere, we will create a Sample1 class then create a new class Sample2 by extending the feature of Sample1 class using the Inherits keyword.Program/Source Code:The source code to demonstrate the simple inheritance is given below. The given program is compiled...
避免如下 power features:meta class(这个似乎非常强大的,居然禁掉了),access to byte code,on the fly compilation,dynamic inheritance,object reparenting,import hacks,reflection,modification of system internals,看起来是下一个学习 python 的起点呀 书写风格 避免使用 ; 在同一行上写两行代码 行宽80 return ...

与C++ 类似的可能就是 python,尽管没有那么多复杂的访问控制,python 也使用了 multiple inheritance,但使用了 linearization。相对 C++ 这样复杂的模型,Java 其实做了很大的简化,这包括 默认的方法就是 virtual 的,子类就能覆盖并产生多态 引入abstract 关键字来标识 pure virtual 函数或者类 ...
