为了实现继承这个特性,编程语言需要提供特殊的语法机制来支持,比如Java使用extends关键字来实现继承,C++使用冒号(class B:public A),Python使用parentheses(),Ruby使用<。不过,有些编程语言只支持单继承,不支持多重继承,比如Java、PHP、C#、Ruby等,而有些编程语言既支持单重继承,也支持多重继承,比如C++、Python、Perl...

一直往下找,最终都能够找到 Object类,不仅是 Sprite,所有的类皆如此,这就叫单根继承。AS 单根继承的思想应该说是从 Java 借鉴来的,实践证明单根继承取得了很大的成功。Java 发明的单根继承摒弃了 C++ 的多继承所带来的很多问题。 虽然在 AS 3 中不能直接利用多继承,但是可以通过实现多个接口(interface)达到相同的...
