- 继承关系Generalization:类与类,或接口与接口之间的父子关系 - 实现关系Implementation: 接口或抽象类定义好的操作集合,由实现类完成接口或抽象类的具体操作 其实从更宽泛的角度来说,类与类之间的关系其实只有三种:继承、实现、关联(依赖是一种弱关联,聚合和组合是关联中的特例)。继承和实现是类与类之间的纵向关系...

So we have a Python implementation written in C, one in Java, and one in C#. The next logical step: a Python implementation written in…Python. (The educated reader will note that this is slightly misleading.) Here’s where things might get confusing. First, lets discuss just-in-time (...
