如何在UML中建模关联数组? [英] How to model associative arrays in UML?

问题描述

我知道有关此问题的一些相关问题，例如此，此和

I know there are some related questions about this question, such as this, this and this, but no one of them really helped me. My array keys are dynamic, so I can't create an additional class holding this attributes (like done in second linked question).

我的概念的想法是持有类的实例，如下所示:

The idea of my concept is to hold instances of classes as follows:

$instances = [
    "nameOfClass" => [
        //instances of "nameOfClass"
    ],
    "nameOfClass2" => [
        //instances of "nameOfClass2"
    ]
    //some more classes
];

但是当array-key与类名一致时，我不知道如何用UML为这些概念建模.

But I don't know how to model these concept with UML when the array-key is unanimously with the class-name.

有没有一种方法可以对我的概念/一般的关联数组进行建模?

Is there a way to model my concept/in general associative arrays?

推荐答案

用UML表示此问题的正确方法是使用限定符或限定的关联.那里您有一个拥有者，并且拥有一个与班级相关联的限定词(即键").此外，您可以给限定符指定一个类型，以表示您的键是某个类的String，int或Object.

The correct way to express this in UML is to use a qualifier, or qualified association. There you have an owner and that has a qualifier, i.e., "key", that associates to a class. Further you can give the qualifier a type, to express that your key is a String, int, or Object of a certain class.
