界面中的访问修饰符 [英] access modifiers in interface

问题描述

大家好，

众所周知，在接口中，所有方法都必须是公共的，我们不能定义私有或受保护的方法.如果我们尝试尝试，则编译器将给出错误，因为它定义了接口.

我的问题是，为什么接口不接受除public之外的访问修饰符，其背后的原因是什么?

在此先感谢:)

Hi to all,

As we know in an interface all methods must be public, we can not define private or protected methods. If we will try then compiler will give the error because its definition of the interface.

My question is why interfaces do not accept access modifiers other then public and what are the reasons behind it?

Thanks in advance :)

推荐答案

因为这是接口的定义.
在C ++中，仍然可能具有接口的访问说明符，因为接口只不过是一个结构.

Because that is the definition of an interface.
In C++ it is still possible to have access specifiers for an interface because an interface is nothing but a struct.

非公共接口背后的原因是什么? :)

一个类的所有非公共方法都可以直接访问
(，如果您有适当的此上下文...
...在接口调用中不是这种情况):)

What would be a reason behind non-public interfaces ? :)

All non-public methods of a class could be accessed directly
(, if you have an appropriate this-context...
...that is not a case at an interface call) :)

因为这是接口定义(接口是合约).
接口中私有方法的含义是什么?
:)

Because that''s the interface definition (an interface is a contract).
What would be the sense of a private method in a interface?
