![]() In this post, we will install and use the ObjectAid plugin for Eclipse to produce jUnit lib class diagrams. Moreover, you can print and bring them to table to discuss a design. Javadoc ) and allow to better explore/understand a design. From my experience thus far, the enterprise edition will be worth the investment.UML diagrams compliment inline documentation ( The freely available version makes me very curious to work witht the enterprise edition. version controlled) projects is a rather severe one and quite annoying, in my humble opinion. Of course, this is unreasonable to expect from a free edition, however the limitation not to be able to work with Team (i.e. The free version does not pretend to be a fully-fledged UML package, hence it is not offering advanced/professional features such as automated design pattern recognition nor a selection of design patterns from a library when designing a model. Synchronization between diagrams and code can be done at any point in time. Diagrams are highly customizable and the performance is reasonably good. Although the plugin takes some time to get used to (typically one or two days), I found it much more pleasant to work with than e.g. This plugin takes away all the disadvantages working with UML diagrams as they were mentioned in the introduction. The tool could have saved me quite some time during my last project! It brings almost full round-trip engineering at no cost. In addition, diagrams can be exported asĪlthough the free edition has some serious limitations, such as no support for projects under CVS source control nor generation of interaction diagrams with reverse engineering, the package offers enough already to make it worthwhile to install (and use!). Rational Rose understands this format as well). This is most likely due to the underlying Eclipse Modeling Framework (EMF), but quite standard in “modelling land” (e.g. ucd files, which are in fact XMI (XML Metadata Interchange) based files. Export of diagrams in various formats.Code (classes, interfaces, methods, attributes, documentation) is being generated when designing/drawing a UML diagram class diagrams.Diagrams are clear and highly customizable, such as visibility and per class sorting of methods and attributes.Reverse engineering from byte code (!!) is possible, although I did not try this myself at home □.Many options and much flexibility is offered via context sensitive menus Generate diagrams all in once or in a stepwise fashion.Inheritance, association and dependency exploration.Generate class and package diagrams from source.Some more details I “discovered” during evaluation: The features supported in the free edition are listed in this table on the Omondo website. ![]() Installation with the auto-installer is straightforward and from then on everything worked smoothly on my Eclipse 3.1 base-installation on a Pentium III 1 Ghz with 640 MB of RAM. Tools not integrated in development environmentĬonsequently, the use of UML diagrams is often much less useful than it could and should be and hence quite often neglected all together, unfortunately.Model/documentation and code run out of sync easily.Method names, attributes and so on have to be typed in twice.Visio 2003 (Windows) or dia (Linux) has serveral drawbacks: Interaction diagram, representing the dynamic relations = behaviour, being realized as either collaboration or sequence diagrams.ĭrawing such diagrams using e.g.Package & class diagrams, representing the static relations and structure between the packages and classes.In my opinion, two diagram types are indispensable here: the development and documentation of Java code using UML. In this review I will mainly focus on the implementation phase, i.e. In a forthcoming post, I’ll present a more indepth howto on the installation and its use. Recently a version for the latest Eclipse 3 became available. In this post I will review the freely available Omondo UML plugin for Eclipse. UML diagrams are used during (almost) the whole software product development life cycle: from requirements analysis (use case diagrams) to deployment (deployment diagrams).
