问题描述

我有一个关于UML的问题.我有一个类，该类简单地包含一个带有私人访问修饰符的内部类 - 无法从其他任何地方访问...通常是为了提出内部类关系，我可以使用(+)的关系(+)关系(InnerOddIterator):

我还没有找到有关如何清楚地强调该类是私人的任何信息.您知道是否存在这种方法?如果是，我很感激您在这里给我一些链接?

只是为了保持清晰，示例代码:

public class DataStrucure {
     // fields, methods, etc
     private class InnerOddIterator{
          // ... 
     };
}

其他推荐答案

首先:您的代码中有一些内容并要求使用UML表示.但是，恕我直言，您应该以相反的方式看待它:如何用代码表示该UML-IDEA. (某些编程语言甚至不提供私人嵌套类...).

至于私人嵌套类:我建议使用构图.它更强大，但不如继承那么强.如果没有其作曲家，那么组成的班级就不可能存在.几乎完全是一个私人嵌套班.

为了表明您的内部类是最好的，对我来说是最好的 - 如下所示，但在这种情况下，您会错过内部类的内部结构. 在此处输入图像描述

问题描述

I have a question regarding UML. I have a class which simply contains an inner class with the private access modifier - cannot be accessed from anywhere else... Normally in order to present an inner class relation I can use a (+) relation like here (InnerOddIterator):

I have not found anywhere any information about how can clearly emphasize that this class is private. Do you know if such a method exist at all? If yes I'll be grateful you give me some link here or something?

Just to keep things clear, a sample code:

public class DataStrucure {
     // fields, methods, etc
     private class InnerOddIterator{
          // ... 
     };
}

First of all: You have something in your code and asking for an UML representation. But, IMHO, you should look at it the other way round: How can that UML-idea be represented in code. (Some programming languages don't even offer private nested classes...).

As for private nested classes: I suggest using a Composition. It is stronger as Association but not as strong as inheritance. And the composed class can not exist without its composer. Pretty much exactly a private nested class.

In order to indicate that your inner class is privete the best, for me, is to use - character as depicted below but of course in this case you miss the internal structure of your inner class.. enter image description here
