In the state pattern how is this modeled ? state A to state B on trigger X and conditon C1 when current state is A state A to state C on trigger X and condition C2 when current state is A how is this usually accomplished ? I have a lot of guard conditions that I may need to implement. That's pretty standard see e.g. this example . [Edited on basis it's not homework!] Assuming I understand right: You have one event ( X ) which can trigger one of two possible transitions Selecting which transition to fire is made according to which condition holds true ( C1 or C2 ) If so that's a standard case

I have an application that models a tree, with classes Tree, Node and Edge (I need the Edge class!), and I'm not sure how to represent the relationships in the class diagram for this. I've read other posts about this, but am still in doubt. The Tree object have a pointer to a Node (its root), which I believe defines an one-way association (Tree -> Node) with multiplicity 1..1 in both ends. Is it right? Each Node object have pointers to the edges that comes out of it (Edge objects). Since these edges only exist if the node exist, I believe it's a composition association. But then I have, in

I am trying to convert a file exported from PowerDesigner in the UML 1.3 - XMI 1.1 format to the UML 2.1 XMI Interchange Model from Rational Software Architect. How can I do this? chooselife It can be worth to give a try to the XMI file converter its web based using Php. If RSA won't import XMI 1.1 then you'll need to find another tool that will. Enterprise Architect by Sparx Systems can import XMI 1.1 and can write XMI 2.1. You can get a free 30 day trial from their website at http://www.sparxsystems.com . Be warned though that there are different dialects of XMI, so you may need to try a

For a school assignment, we have to make a Usecase diagram. But the documentation that we have, is not very extended. It just describes what components a usecase consists of, and one example. We have to make a usecase about a library system. We have found 11 usecases, but I won't bother you with all of them. IIRC, a usecase describes a typical usage of a system, right? But what things belong on a usecase diagram, and how do they connect together? What we have now are four actors (member, employee, manager and accountant). The ones we have most problems with are member and employee. The

Is there a way to generate UML Class diagram for swift programming language? I found that the Mac A&D tool claims to be able to scan the swift code and create a class diagram. And there is a video to introduce it. https://wn.com/swift_code_to_class_diagram Unfortunately, it is not free. I wonder if there is another free tool to generate class diagram automatically. Could you guys help me? Thanks in advance. UML class diagrams for Xcode (swift programming) I recently found a free tool, that gets you a decent start on this. Take a look at this tutorial https://martinmitrevski.com/2016/10/12
