4.1.4.5 表面特征附着(Surface Feature Adherence)

附着表示宿主结构(称为“宿主”)与附着组件(称为“附着元素”)之间的外部部分组合关系。附着的概念有多种用途,例如:

  • 附着可用于建筑构件,用于附着表面特征,这些特征以标记、表面处理或缺陷的形式对宿主构件进行修饰。

附着是一种双向关系,从宿主结构到其附加组件的关系称为附着(Adherence),从组件到其宿主结构的关系称为宿主(Hosting)。

下图展示了应用此概念时使用的通用类和关系。 此外,概念可能对常见或标准化的行业实践和场景具有特殊意义。对于这些特定的使用场景,下表展示了用户可采用的推荐通用使用模式列表。
