你也可以使用下面这些关键字来声明参与者，这会改变参与者的外观： • actor（角色） • boundary（边界） • control（控制） • entity（实体） • database（数据库） • collections（集合） • queue（队列） @startuml participant participant as Foo actor actor as Foo1 boundary User << Human >> :Main Database: as MySql << Application >> (Start) << One Shot >> (Use the application) as (Use) << Main >> User -> (Start) User --> (Use) MySql --> (Use) @enduml 2.10 改变箭头方向 默认连 User << Human >> :Main Database: as MySql << Application >> (Start) << One Shot >> (Use the application) as (Use) << Main >> User -> (Start) User --> (Use) MySql --> (Use) @enduml 2.14 一个完整的例子 @startuml

使用这些其他的关键字来声明参与者，将改变参与者的表示形状。 • actor（角色） • boundary（边界） • control（控制） • entity（实体） • database（数据库） • collections（集合） • queue（队列） @startuml participant Participant as Foo actor Actor as Foo1 boundary User << Human >> :Main Database: as MySql << Application >> (Start) << One Shot >> (Use the application) as (Use) << Main >> User -> (Start) User --> (Use) MySql --> (Use) @enduml 2.10 改变箭头方向 默认情况下，类之间的链接有两个破折号-- User << Human >> :Main Database: as MySql << Application >> (Start) << One Shot >> (Use the application) as (Use) << Main >> User -> (Start) User --> (Use) MySql --> (Use) @enduml 2.14 完整样例 @startuml

� 图 ��� 显示了开发的后期阶段预订票交互的协作图 协作显示了对于订票 应用程序内 部对象的交互 来自售票亭的请求被用于在数据库中从所有的演出中选择特定的一场 返 回给售票员 售票员 售票员 售票员 ������������ 的指针 �� 表达了至演出节目数据库的暂时性链 该链在交互中 维持以及完成后被丢弃 售票员需要节目的若干座位 不同价格范围座位选择项被获得 并暂时被锁定 接着返回给售票亭以供顾客选择 性 图 ��� 展示了关联之间的 ��� 约束 对象仅能拥有其中之一 约束适用于用文字表达 ��� 结构不直接支持的陈述 � 构件 ������ 上的版型指明了该构件是数据库 它允许省略构件所支持的接口 因为它 们是被所有数据库支持的接口 建模人员可以增加新的版型来表达特殊的元素 一系列约 束 标签值或代码特性可以附加至版型 建模人员可以为给定的版型名称定义图标 以作 为辅助 当然 文字形式仍可使用 链是关联的一个实例 链是对象引用的有序列表 每个对象引用必须是关联中相应类 的一个实例或者类后代的一个实例 系统中的链是系统状态的组成部分 链不会独立于对 象而存在 它们从相关联的对象获取标识 在数据库术语中 对象列表是链的主键 概念 上 链独立于相关联的类 而在实践中 关联常常用参与类中的指针来实现 它们也可用 于独立于所连接类的容器来实现 � 双向性 双向性 双向性 双向性 关联的不同端点是可以区分的
