在计算机面向对象的体系结构中,具有关联类。关联类既是类也是关联。它有着关联和类的特性。它将多个类连接起来同时又具有属性和操作。
可以用多种方法建立关联,包括在地图中临时连接或关联各表,或者在geodatabase中创建关联类(relationship classes),它可以存储很多永久的关连类。

范例模型显示了原型关联与原型关联类之间的不同。
The example model shows the difference between the stereotyped association and the stereotyped association class.
首先,关联表的目的是实现关联,而关联类的目的是描述关联。
First, the purpose of an associative table is to implement an association, whereas the purpose of an associative class is to describe an association.
通过按照上面总结的步骤操作,您可以在模型中定制您的模型以为关联类上的原型生成工具代码。
By following the steps outlined above, you can now customize your profile tooling model in order to permit the generation of tooling code for stereotypes on association classes.
Some of which I built: cmp, init, str. And there, notice, are the internal definitions And in fact I should've said, we often call those things fields.
就是给我一个所有东西的列表:,所有的方法,与这个类关联的,有一些是我写的:,还有这里,请注意,是一些内部的定义。
They are instances of a class, and associated with that class is a set of methods.
它们是同一个类的实例,与这个类相关联的是一个方法集,因此例如,我可以说。
So you can actually say, how do I know which methods are associated with the class? For that, we can call dir. And what it does, is it gives me back a listing of all the things, dir all the methods, that are associated with it.
我们开始建立类了,我们得到了这些方法,因此实际上你可以说,我怎么知道,哪些方法是关联与这些类的?,为了解决这个问题,我们可以调用,这个方法的作用。
