![]() ![]() ![]() You have variety of options about the colors, arrows (the type of requests, responses), you can add Activation sections, different interaction fragments, comments and everything you will potentially need from a sequence diagram. The above code will result in the following sequence diagram: "Login Page" -> "Restricted Page": Redirect to the \nrestricted you save the text file the plantuml application will generate a png image for you. "Login Page" -> "Login Page": Show error \nmessage I installed the PlantUML extension (by jebbs) in Visual Studio Code for Windows and everything is working perfectly for sequence diagrams. "Restricted Page" -> "Login Page": Redirect "Restricted Page" -> "Restricted Page": Open page ![]() Let’s give it a try and describe that with the plantUML language: User There are two possible situations here – one is to authenticate the user and redirect him back to the restricted page, and the other is to fail his authentication due to invalid username or password and show him a message. If the user is already authenticated he will be allowed to just open the restricted page, otherwise he is redirected to a login page where he enters his credentials. Imagine a scenario where a user tries to access a restricted area in a web site. It does not matter whether its C (not-/) or C (OO). If you have some code written in the some objected language its possible to generate sequence diagram especially in the visual paradigm (tool for creating UML diagrams). Let me give you an example of plantUML format in order to clear the process and the idea. So if you ask me, it is not possible no generate sequence diagram from the code written in the C. I am going to create a txt file for that purpose in the selected directory. When you open it it will display the following window:įrom here you can set the directory, where the plantuml description file will be positioned. For the other types of diagrams we will also require a software called Graphiz.įirst of all you will need to download the plantuml.jar from here: The reason I choose exactly this type of diagrams is that we will only need the plantuml.jar file for that purpose. You can create all kinds of diagrams with it, but today I am going to illustrate this component by focusing only on the sequence diagrams. The idea is to describe the content of your diagrams using a simple language and then PlantUML will create the visual representation for you. It can be considered as a standard of making UML, because the output is auto-generated and thus unified. Recently I came across PlantUML as a tool for building UML diagrams. ![]()
