UML平方图-可视化数据验证 [英] UML Squence Diagram - visualize validation of data

问题描述

一种方法对一些传递的数据进行连续的验证检查。
如果验证检查失败，则将立即引发异常并且该方法将中止。

A method performs successively validation checks with some passed data. If a validation check fails, a exception will be immediately thrown and the method aborted.

如何用UML序列图可视化此流程？

How can visualize this flow with UML sequence diagrams? Is it possible / allowed to show exceptions in sequence diagrams?

一种可能的解决方案也许是使用嵌套替代方法。

A possible solution perhaps is to use nested alternatives.

推荐答案

UML不提供特定于模型异常的内容。查看 http://www.uml-diagrams.org/sequence-diagrams -questions-answers.html

UML does not provide something specific to model exceptions. Look at http://www.uml-diagrams.org/sequence-diagrams-questions-answers.html

但是，有一些方法可以在序列图中对其进行建模。您可以在 http://www.ibm.com/developerworks上了解有关序列图的更多信息。 /rational/library/3101.html

However there are ways to model it in a sequence diagram. You can read more about sequence diagrams at http://www.ibm.com/developerworks/rational/library/3101.html

我更喜欢忽略序列图中的异常。在您的情况下，我会将所有验证都包含在仅能进行验证的一种方法中。因此，此方法的序列图将仅显示验证步骤。

I prefer to ignore exceptions from sequence diagrams. In your case, I would include all validations in one method that only makes that. So the sequence diagram of this method would show the validation steps only.
