UML用于C编程语言

问题描述

UML最常用于使用C ++建模系统。在我的项目中，C是实现语言。我正在寻找适用于C的UML策略的资源。我想在设计过程中使用UML，代表系统的不同方面。

解决方案

我不知道有什么现有资源讨论使用UML专门为C。如其他人所说，UML是语言无关的。

保持请记住，使用UML，您可以有一个问题域的模型，另一个用于实现。尽量不要用C来对问题领域进行建模，而应该是高级别的OO。一旦您充分了解问题域，就可以开始对实现进行建模。

对于建模过程式C实现，以下图可能很有用：

• 类图：
  
  
  
  
  • 显示C模块API
  
  
  • 显示C模块关系（主要是非OO的依赖关系）
  
  
  • 显示结构和枚举（使用<< stereotype>）
  
  


• 包图：显示库的内容（模块）以及库之间的依赖关系


• 活动图：流程图的非平凡算法


• 顺序/协作图：显示模块/实体/输入/输出之间的事件/消息如何及时发生


• 状态图：对于状态机，当然！

在类图上展开，您可以以下列方式对其进行滥用：对程序式C：

• Glo外部函数 - > public方法


• 本地静态函数 - >私有方法


• 全局外部变量 - > public成员


• 本地静态变量 - >私有成员


• 结构 - >具有struct原型的类



• 定义常量 - >类使用枚举原型

实验，你会发现自己的滥用UML的惯例。

UML is most commonly used for modelling system by using C++. In my projects C is the implementation language. I am looking for resources on UML strategies which are applicable for C. I want to use UML during design and represent the different aspects of the system.

解决方案

I don't know of any existing resources that discuss using UML specifically for C. As others have mentioned, UML is language-agnostic.

Keep in mind that with UML, you can have a model for the problem domain, and another for the implementation. Try not to model the problem domain in terms of C, but rather as high-level OO. Once you understand the problem domain adequately enough, you can begin modeling an implementation.

For modeling procedural-style C implementations, the following diagrams could be useful:

• Class diagram:
  • Show C module APIs
  • Show C module relationships (mostly dependencies for non-OO)
  • Show structures and enumerations (using < < stereotype> >)
• Package diagram: Show contents (modules) of libraries, and the dependency relationships between libraries
• Activity diagram: Flowcharting non-trivial algorithms
• Sequence/collaboration diagram: Show how events/messages between modules/entities/inputs/outputs occur in time
• Statechart diagram: For state machines, of course!

Expanding on class diagrams, you can "abuse" them in the following way for procedural-style C:

• Global extern functions -> public methods
• Local static functions -> private methods
• Global extern variables -> public members
• Local static variables -> private members
• Structs -> class with "struct" stereotype

• define constants -> class with "enumeration" stereotype

Experiment, and you'll find your own conventions for abusing UML.
