sequence-diagram

How can you clearly illustrate multiple threads of execution in a sequence diagram or similar diagram? I haven't been able to find any clear examples. All diagrams I see are used to illustrate a single thread. Update : The accepted answer was the best example I saw but it does leave a fair bit to be desired. I ended up illustrating the threads in separate sequence diagrams. I'm not sure if the sequence diagram necessarily works for multiple threads. James Black Here is one diagram that may be useful, and on the left-hand side you can see the explanation: http://sdedit.sourceforge.net

I'm looking for a tool that will reverse engineer Java into a sequence diagram BUT also provides the ability to filter out calls to certain libraries. For example, the Netbeans IDE does a fantastic job of this but it includes all calls to String or Integer which clutter up the diagram to the point it is unusable. Any help is greatly appreciated!!!!!!! I think jtracert is what you are looking for. It generates a sequence diagram from a running Java program. Also, because its output is a text description of the diagram (in the formats of several popular SD tools), you can use grep to filter for

My objective is to stimulate a sequence diagram of an application for this I need the information about a caller and callee class names at runtime. I can successfully retrieve the caller function but not able to get a caller class name? #Scenario caller.py: import inspect class A: def Apple(self): print "Hello" b=B() b.Bad() class B: def Bad(self): print"dude" print inspect.stack() a=A() a.Apple() When I printed the stack there was no information about the caller class. So is it possible to retrieve the caller class during runtime ? Well, after some digging at the prompt, here's what I get:

I was wondering, how can one represent " if " statement on a sequence diagram? if (somethingShouldBeDone) { // Do it } else { // Do something else } Can it be represented at all? The thing is ... in my code, fair amount of conditions are checked to determine a variety of actions. If i am going to show the actions, I'd like to explicitly state that actions are caused by particular events. If possible create an image representation of a solution. GETah If else condition, also called alternatives in UML terms can indeed be represented in sequence diagrams. Here is a link where you can find some

I tried (though not very comprehensively) numerous solutions including ModelGoon (only class and interaction diagrams available), ObjectAid (class diagram only), eUML free edition (quits with an ominous "license not found" error on first use), MoDisco (with the only option on the menu being "browse corresponding model element"). And also some standalone tools - ArgoUML and BOUML either dont provide this feature or at least i was not able to find it. Jsonde started only after i fixed a msvcr71.dll-error and was then unable to connect to the VM for reasons unknown... Java Call Tracer is just a

Which UML diagram is the best for showing dependency between our IT system and other external IT systems? For example I would like to show on diagram: system A gets data from system B system B can call some functionality from system A I'm wondering between component diagram and sequence diagram. What do you think? Components definitelly, and dependencies. Dependency does not go in direction of the data-flow, but from the component that "knows" other component (invokes something from it, creates an object, etc). The following diagram shows the idea. It is common (and highly recommendable)
