mermaid类图关系语法

  • 泛化（Inheritance）

    • 一种继承关系，表示一般与特殊的关系，它指定了子类如何特化父类的所有特征和行为。例如：老虎是动物的一种，即有老虎的特性也有动物的共性。
    • 箭头指向:带三角箭头的实线，子类指向父类
    • mermaid语法: A --|> B

  • 关联（Association)

    • 是一种拥有的关系，它使一个类知道另一个类的属性和方法；如：老师与学生，丈夫与妻子关联可以是双向的，也可以是单向的
    • 双向的关联可以有两个箭头或者没有箭头，单向的关联有一个箭头
    • 代码体现:成员变量
    • 箭头指向:带普通箭头的实线，拥有者指向被拥有者
    • mermaid语法:A "1" --> "n" B

  • 聚合（Aggregation）

    • 整体与部分的关系，且部分可以离开整体而单独存在,如车和轮胎是整体和部分的关系，轮胎离开车仍然可以存在.
    • 聚合关系是关联关系的一种，是强关联；关联和聚合在语法上无法区分，必须考察具体的逻辑关系
    • 代码体现:成员变量
    • 箭头指向:带空心菱形的实心线，菱形指向整体.
    • mermaid语法:A o-- B
