UML多重性的语法是什么? (在班级框内) [英] What's the UML syntax for multiplicity? ( inside the class box )

问题描述

我知道可以在同一类框中指定多重性，而不必绘制到另一个类的链接.

I know it is possible to specify the multiplicity within the same class box, without having to draw the link to another class.

我的问题是，名称或类型后面的多重性应该去哪里?

My question is, Where should the multiplicity go, after the name or after the type?

是吗

可见性名称多重性:类型

为

+ clients [0..n] : Client

或

可见性名称:输入多重性

为

+ clients : Client [0..n]

我有两本书(Larman和UML的《应用UML和模式》以及Arlow和Newstadt的《统一过程》)，但它们有所不同

I have two books (Applitying UML and Patterns by Larman and UML and the Unified process by Arlow and Newstadt ) but they differ
