如何在不公开给所有类的情况下公开接口中的方法 [英] How to expose a method in an interface without making it public to all classes

问题描述

我遇到了一个问题，我正在使用一个特定的界面来处理很多事情.但是，我有一个特定的方法，我希望它只对特定的一组类可用(基本上，一个 internal 方法).

I have a issue where I'm working with a particular interface for quite a lot of things. However, I have a particular method that I want to be available only to a particular group of classes (basically, an internal method).

interface IThing {
    function thisMethodIsPublic():void;
    function thisMethodShouldOnlyBeVisibleToCertainClasses():void;
}

问题是，无法在接口中添加访问修饰符(即公共、私有、内部)——至少在 ActionScript 3.0 中没有.

The problem is, there is no way to add access modifiers (i.e. public, private, internal) in an interface - at least not in ActionScript 3.0.

所以我想知道这里的最佳做法是什么?公开这个内部方法似乎是一种不好的形式，但我需要它成为接口的一部分，这样我才能保证实现它的类具有这个内部方法.

So I'm wondering what would be the best practice here? It seems like bad form to make this internal method public, but I need it to be a part of the interface so I can guarantee that classes that implement it have this internal method.

感谢您的帮助！

推荐答案

答案:定义两个接口，并将私有"功能保留在第二个接口中.如果 ActionScript 支持接口继承，则将私有"接口定义为扩展公共"接口.

Answer: Define two interfaces, and keep the 'private' functions in the second interface. If ActionScript supports inheritance for interfaces, then define the 'private' interface as extending the 'public' interface.
