如何在UML中表达互斥继承? [英] How to express mutually exclusive inheritance in UML?

问题描述

如何举例说明一个类可以继承两个超类中的任何一个，但不能同时继承两个?

How to exemplify that a class can inherit either of two super-classes, but not both?

Property 类可以代表一个集合的数字，或者一个Cardinalstrong> 数字，但不是同一类型.

The class Property can either represent a Set of numbers, or a Cardinal number, BUT not both at the same type.

推荐答案

你的子类是颠倒的.您需要一个 Set Property 和一个专门用于 Property 的 Cardinal Property.如果这些子类也具有 Set 和 Cardinal 的特征，您也可以将它们子类化.

Your sub classing is upside down. You need a Set Property and a Cardinal Property that specialize Property. If those subclasses also have characteristics of Set and Cardinal, you could subclass those as well.
