StarUML笔记之从C++代码生成UML图

—— 2024-04-14

1.安装C++插件

2.准备好一个C++代码文件放某个路径下

main.cpp

#include <iostream>
#include <string>class Shape {
public:// 构造函数Shape(const std::string& name) : name_(name) {}// 纯虚函数，用于返回形状的面积virtual double area() const = 0;// 虚析构函数virtual ~Shape() {}// 输出形状的信息void printInfo() const {std::cout << "Shape: " << name_ << ", Area: " << area() << std::endl;}protected:std::string name_;
};class Circle : public Shape {
public:// 构造函数Circle(const std::string& name, double radius) : Shape(name), radius_(radius) {}// 实现基类中的纯虚函数virtual double area() const override {return 3.14159 * radius_ * radius_;}private:double radius_;
};class Rectangle : public Shape {
public:// 构造函数Rectangle(const std::string& name, double width, double height): Shape(name), width_(width), height_(height) {}// 实现基类中的纯虚函数virtual double area() const override {return width_ * height_;}private:double width_;double height_;
};int main() {Circle circle("Circle 1", 5.0);Rectangle rectangle("Rectangle 1", 4.0, 5.0);circle.printInfo();rectangle.printInfo();return 0;
}

3.点击Reverse Code选择项目文件夹

4.拖动(Class)到中间画面可以形成UML

5.另外一种方式：双击Type Hierarchy，然后拖动(Class)到中间画面可以形成UML带箭头指向

6.可以更改UML样式

样式更改后新的UML：
