如何表示一个类的实例与将该类作为输入的类之间的关系?

问题描述

我有一个叫做 House 的类.此类的实例是 house .

I have a class called House. The instance of this class is house.

class House:
    def __init__(self, height, length):
        self.height = height
        self.length = length

    def housePlan():
        houseHeight = self.height
        houseEdgeLength = self.length

house = House(height,length)

我还有一个叫做 Person 的课程.此类获得一些输入，包括 House 的实例.

I have another class called Person. This class gets several inputs including an instance of House.

class Person:
    def __init__(self,name, house):
        self.name = name
        self.house = house

问题我想向观众展示我的程序，我如何将这些关系与图表展示出来?

Question I would like to present my program to an audiance, how I can present these relationships with diagrams?

推荐答案

House 的实例不仅在 Person 的构造函数的参数中给出，而且是类的属性( self.house = house )，因此:

the instance of House is not only given in argument of the constructor of Person but it is a property of the class (self.house = house), so :

我说过 name 是很有可能的 String .

所有属性/属性/操作都是公开的，以遵守Python规则.

All attributes / property / operations are public to respect Python rules.

在类图的级别上，无法看到操作的参数来自何处，因为您可以使用交互(例如，在您下一个问题中的序列图，我也将一个 answer )或一项活动

At the level of a class diagram it is not possible to see from where the arguments of the operation come from, for that you can use an interaction (e.g. a sequence diagram like in your next question where I also put an answer) or an activity

(奇怪的是，您的房子只有长度但没有宽度，因此必须是正方形)

(Out of that it is strange your house has a length but not a width, so it is mandatory a square)
