9.2.6 Inheritance

Each class inherits the instance traits of its base class. These traits are effectively copied down to the instance traits of the derived class. Classes that don't declare an explicit base class inherit the built-in Object class.

A class may also inherit the instance traits of one or more interfaces. Interface traits are abstract and so must be implemented by any class that inherits them.

Unlike static properties in other object-oriented languages, such as Java, static properties in ActionScript are not inherited, but they are in scope in the static and instance methods of the derived class.
