Comments on: One of a kind – Generating UUID with EMF

For those interested I’ve written a small Eclipse Plugin to make generating UUIDs as simple as possible when you are inside your IDE. For more details see: http://tomsondev.bestsolution.at/2010/10/20/uuid-generator-plugin/

I think EMF might have introduced its own variant because EMF did not originally target 1.5. I myself did not know of the java.util.UUID class until I read Bryan’s comment since I’ve primarily been working with 1.4 until e4 came along.

@Lars No worries! As a well-known critic of the role of EMF in e4, this type of thing is just ‘Gefundenes Fressen’. I am perfectly happy to see EMF continue its MDD quest, but not as a core part of the framework. I feel that EMF lacks the maturity and the broad appeal it needs to warrant adoption on this level by this community.

Because EMF is being pushed down our throats, I now have to spend time on criticizing, instead of on helping the Eclipse community to work for everyone. That’s pretty sad.

EMF wants to be in the driver seat? You’d better buckle up, then

@Dann Sorry, but I don’t know why EMF has re-implemented this. I’m also not aware of the difference between both implementations. If you want to know I suggest to check on the EMF forum.

I am a bit puzzled by this claim. Being familiar with this RFC, I know it details different versions and variants, which can be particularly relevant for the context the UUID is used in.

The UUID utility class from the java.util library supports several of these. Why exactly has this wheel been reinvented?

Ironically, as I consider a project like EMF quite bloated, should I now conclude that part of the cause for that is that standard Java classes have been rewritten?

@Bryan: Thanks for the info!

You can also use java.util.UUID.randomUUID() to achive the same result without EMF.
