I have an Interface say Interface ICallback { public void informFunction(); } I have a Class say: Class Implementation implements ICallback { public Implementation() { new AnotherImplementation(this); } @override public void informFunction() { // do something } } Now consider a class where in the instance of Class Implementation is passed as a interface and is used to make a callback. Class AnotherImplementation { public ICallback mCallback; public AnotherImplementation(ICallback callback) { mCallback = callback; } public void testFunction() { mCallback.informFunction(); // Callback } } Now I

In a use case diagram what is the difference between <<includes>> , <<extends>> and <<uses>> ? Are <<includes>> and <<uses>> are the same thing? includes and uses are the same. From http://www.agilemodeling.com/essays/useCaseReuse.htm above An include dependency, formerly known as a uses relationship in UML v1.2 and earlier Nice writeup here: http://www.agilemodeling.com/essays/useCaseReuse.htm Summary from that article: An extending use case continues the behavior of a base use case. An include dependency is a generalization relationship denoting the inclusion of the behavior described by

I've just stumbled into the job of analysing a project for one of my company's clients (an SMB). I am a .Net developer (5 years) with little experience in analysing software (UML from school). We've just finished two weeks of talking with the users and got a nice big list of requirements. Obviously we've filtered out the most important requirements and had to mark a bunch as 'out of scope'. I have just started making some usecases, but feel I don't have the required expertise to bring this entire project to a good end. I'd like to know if someone has made the leap from developer to analyst and

I stumbled across a free state machine tool . This appears to be for programming embedded systems graphically. By doing so, the author claims that the resulting code is more maintainable than if an RTOS had been employed. This tool is based on UML, which is nice to know, but has a steep learning curve. I would like to know what some of the more experienced programmers here think of this tool. I am developing an embedded application for the LM3S5P36 microcontroller. TI has an IDE called Code Composer Studio (CCS). I have not got into CCS yet, but I doubt it has the cool feature of being able to

I would like to create diagram class using pyreverse. I download it, and when I use this command: pyreverse.bat -c PyreverseCommand -a1 -s1 -f ALL -o png test.py I get an error "The name 'dot' is not recognized....". What is "dot", how can I create diagram class? Thanks for answers. dot is part of Graphviz ( http://www.graphviz.org/About.php ). You need to install Graphviz and then modify your PATH so Windows (what I assume you are using) can find it. "the command pyreverse generates the diagrams in all formats that graphviz/dot knows." ( http://www.logilab.org/blogentry/6883 .) Once installed

Hi there I want to have a uml sequence diagram with dot language, now I have the following problem I want to have the layout as follows with a, b, c and d in a straight line at top but with the lines going straight to the bottom. How can I achieve that? a b c d | | | | | | | | perhaps can I achieve that the a, b, c and d with its belonging edges are clusters where I set a different rankdir for the clusters? EDIT Just found a solution by adding invisible edges between a, b, c and d but any other solutions? Dave Webb What you describe seems to be what dot does by default. For example, this graph
