Just a very quick post today, which will hopefully be useful to someone other than myself as well.

When using the org.eclipse.emf.common.notify.Notification interface in Eclipse GEF editors, more precisely in any extensions of Adapter or EContentAdapter (cf. respective tutorial at vogella.com) you use in EditParts, you may want to catch certain event types in your Adapter‘s notifyChanged() method.

In my case, I have an Adapter listen to model elements, and want to implement a switch statement for certain event types. I’m able to get the event type in the method via notification.getEventType() and print that to, say, System.out1, but this only gives me an int value. To be able to quickly implement the switch case for this event type, I thought it would be useful to have a list of event types and their corresponding int values. So here it is (one ordered alphabetically, and another one ordered by int value).

I’ve worked on the implementation of a GEF editor for an EMF-based model, using both the GEF book and vainolo‘s great GEF tutorials. The model consists of several types of nodes and connections, with different layout requirements for the display of their figures in the editor, as follows.

EclipseCon Europe 2012 – lessons learned

Last week I went to my first ever developer conference (apart from a local Eclipse Demo Camp for the Juno release): EclipseCon Europe 2012. It could be summed up in one word: GREAT!

In the course of the conference, I’ve learned a great deal about Eclipse, its projects, Java, OSGi (EclipseCon was co-locating with the OSGi Community Event 2012), and programming in general, but also about open source communities, more precisely the Eclipse community.

In this post I’d like to share some of the stuff I’ve learned as well as some more general thoughts about my experiences at EclipseCon.
