Markdown 的原生语法不支持绘制图形但通过扩展模块我们可以将一些格式化的文字渲染成我们需要的图形。常用的图形有 “流程图”、“时序图”、“类图”、“状态图”、“甘特图”、“饼图” 等。
本节将重点介绍如何通过 Mermaid 绘制「类图」。 类图(Class diagrams)用来描述系统中静态对象的内容和关系。 类图是一种面对对象的建模形式。它是应用系统结构的概念模型通常与开发时的代码有严格的对应关系。类视图也可以用于数据建模。
2. 语法详解
2.1 类图的[类]
类是类图中的核心组成类的成员包括属性和方法以及一些扩展信息。在类图中一个类实例由三层组成。
类名称在类图的最顶端类属性在类图的中间层类方法在类图的最下层 实例一 代码
