问题 I am using PlantUML to create an Activity diagram. I want the arrow that comes out of Modify Details to go back to OP2 instead of the diamond. I have this diagram: @startuml |Swimlane1| start :OP1; |Swimlane2| :OP2; if (Form Valid?) then (No) |Swimlane1| :Modify Details; /' <-- This should point _back_ to OP2 '/ |Swimlane2| else (Yes) :Add Detals to System; endif :OP3; |Swimlane2| :foo5; stop @enduml Which gives this image: 回答1: Can you express it with a while or repeat ? Below is not quite

问题 I have made an activity diagram for gym management, but i am facing a problem how will i connect Receptionist with Admin, According to requirement activity between Admin and receptionist takes place only through notification and i have made a signal and receptor for notification. Please also check if every notation is right and suggest me for modification? 回答1: I am sorry for not answering at once - several times had I looked at your picture, and, frightened, retreated. You really tried and

问题 I've got a game that I'm trying to create an activity diagram for but I run into some problems. My try so far looks like this: This shows the flow good, the GUI is created -> Player performs actions one -> Action Two -> Ends turn. But what I don't really like is how I could solve action 3. It is suppose to be optional and can be performed anytime from the "System creates GUI" action up until "Player ends turn". Though, performing action three still doesn't move the player back or forth in the

问题 How to show «include» and «extend» in activity diagram? And how can I show types in activity diagram. E.g. Vehicle is of 2 types i.e Bike and Car. So how can I show this in activity diagram? 回答1: (This answer is independent of whether or not you should use «include» or «extend».) A use case can be specified any number of ways. For some examples, you can use natural language, tables, or activity diagrams. It appears that you would like to specify use cases as activities. In that case, each use

问题 As Thomas Kilian described here, normal behavior of nodes of Activity diagrams with tokens is: A node becomes active when at all of its incoming InformationFlow connectors a token has arrived. When the node finalizes it sends single tokens along all its outgoing InformationFlow connectors. But also he added: There are special nodes like fork and merge which behave a bit different I know that behavior of "merge" node differs because it becomes immediately active by receiving first token and

问题 UML specs 2.5 says: The effect of one ActivityNode on another is specified by the flow of tokens over the ActivityEdges between the ActivityNodes. But above definition is obscure; specially because tokens are not explicitly modeled in an Activity . After reading 15.2.3.3 Activity Edges section of specifications, I think purpose of them is: to capable the diagram to describe it may wait for other token or refuse flow instead of entering next node immediately Is it true? Also is it the only

问题 I had a doubt regarding parallel activities that occur in the system. How can we represent those in the diagram? Is there always a need of fork or the decision element can also be used? Eg.: The user can choose among "Add Book" , "Search Book", "Search User" and "Update profile". So after the user logs in the system he can choose among the above operations. Below is the image of my activity diagram. 回答1: According to http://www.uml-diagrams.org/activity-diagrams-reference.html the .. Fork

问题 We're currently designing an application with an exit button, meaning the user can exit the application at any time. Now, we're not sure how to write this down. Right now, we're thinking about doing it like shown in the picture below, because this is the only way we know how to do this. However, we feel like there must be an easier way. Also: if we do this for our whole application (which is quite big), we'd get a whole ton of decision and end nodes... 回答1: Your model looks ok. Instead of

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . I need to automatically construct flowcharts out of C++ code, ideally one flowchart per source file. Is there any tool (preferably C++/Python and either open-sourced or highly configurable - so I may change the look) that I can use to create flowcharts? 回答1: clang/llvm can generate graphviz dot files. Example:

问题 What is the difference between Join and Merge in Unified Modeling Language Activity Diagram. Give an example to understand more clearly. 回答1: Join Node (see reference 1): Join node is a control node that has multiple incoming edges and one outgoing edge and is used to synchronize incoming concurrent flows . Join nodes are introduced to support parallelism in activities . Merge Node (see reference 2): Merge node is a control node that brings together multiple incoming alternate flows to accept
