简介
使用Clojure封装了Graphviz的使用，目前主要实现了UML的绘制
使用
以命令模式的UML为例，演示cdraw的使用
安装Graphviz
cdraw是对Graphviz的简单封装，请先安装Graphviz
添加依赖
- 使用leiningen新建一个Clojure项目uml
- 在project.clj中添加如下依赖
[com.ivaneye/cdraw "0.2.0"]定义类
- 在uml.core中编写如下代码
(ns uml.core
(:require [cdraw.uml :refer :all]))
(defclass Client)
(defclass Inboker)
(defclass Receiver {:m ["Action()"]})
(defclass Command {:m ["Execute()"]})
(defclass ConcreteCommand {:f ["state"] :m ["Execute()"]})- 第一，二行，引入了cdraw
- defclass定义了类，及其字段(:f)和方法(:m),效果图如下:
添加依赖
- 继续在uml.core中添加依赖代码
(defrelation Client :u Receiver)
(defrelation ConcreteCommand :u Receiver {:t "reveiver"})
(defrelation Client :d ConcreteCommand)
(defrelation ConcreteCommand :e Command)
(defrelation Invoker :p Command)- Client关联Receiver
- ConcreteCommand关联Receiver
- Client依赖ConcreteCommand
- ConcreteCommand继承Command
- Invoker聚合Command
关联 :u
依赖 :d
聚合 :p
组合 :c
继承 :e
实现 :i
添加label
- 在uml.core中添加如下代码
(label ConcreteCommand "receive-\\>Action()")- >需要转义
定义子包
(defsub "Sub Command" Command ConcreteCommand)- 第一个参数为子包名称
- 后续为需要包含到子包中的类
生成
- 在uml.core中添加如下代码
(watch (to-file "/t.dot") "/t.png")- to-file生成符合Graphviz的dot文件
- watch生成需要的最终文件，这里是生成了png图片
最终代码
(ns uml.core
(:require [cdraw.uml :refer :all]))
(defclass Client)
(defclass Invoker)
(defclass Receiver {:m ["Action()"]})
(defclass Command {:m ["Execute()"]})
(defclass ConcreteCommand {:f ["state"] :m ["Execute()"]})
(defrelation Client :u Receiver)
(defrelation ConcreteCommand :u Receiver {:t "reveiver"})
(defrelation Client :d ConcreteCommand)
(defrelation ConcreteCommand :e Command)
(defrelation Invoker :p Command)
(label ConcreteCommand "receive-\\>Action()")
(defsub "Sub Command" Command ConcreteCommand)
(watch (to-file "/t.dot") "/t.png")
