Transforming a model instance to .e4xmi and .fxml [message #1748166] Sun, 20 November 2016 00:16 Go to next message

I'm looking at using ATL to generate an application.e4xmi file from a model instance but I can't find a corresponding .km3 or .ecore file. Where can I find it?

I also need to generate .fxml files which are plain javafx XML files, as opposed to XMI. What would work best for this transformation?

Any suggestions or guidance appreciated.

Of course each project that uses EMF to define models provides their own models and where those might be is determined by that project, so best you ask each project's forum about that.

One trick you might use is if you have any *.ecore open, you can use Load Resource... from the context menu and then use either Browser Target Platform Packages... (packages available in the target platform) or Browse Registered Packages... (packages registered in the running IDE/application) to locate packages of interest.

I don't know anything about javafx XML files. Perhaps https://www.eclipse.org/efxclipse/index.html provides something useful for this purpose.

Ed, thanks for taking the time to respond.

A link to the .ecore files for .e4xmi can be found in this topic.

As for .fxml, a quick review of the M2T (model-to-text transformation) forum show Acceleo and Xpand are in use. Interestingly wiki.eclipse.org/Xpand -> Tutorial leads to www.eclipse.org/Xtext. Which would you recommend or are there any other M2T tools I should be considering?

I would have expected an XML language to have an XML Schema, but I suppose that's not the case?

Googling "javafx.ecore" just turns up my M2T topic. Interestingly I found an explanation here. Search for "There will"

Quote:
There will never be a full reference (nor xml schema) for FXML as it works by reflecting on Java classes in the classpath and defining elements and attributes based on the properties of the classes.


I've been posting here as well. Maybe Xpand or a M2T other than Acceleo would be better suited. Please let me know if you are aware any.

Cheers.

Hi

Then Modisco may be perfect since I think it can (easily be extended to) reflect on the classpath and produce an Ecore file.

Hi Ed Willink,

I'm going to try and use Epsilon because I'm a little bit out of my depth with Modisco. However if that doesn't work out is there any chance you could produce the Ecore file?

Thanks Ed and Ed.

Hi

To be honest, if I was doing this myself, I would use Java to create the missing Ecore (instance) model since I already have a classpath scan that I am familiar with:

doFullScan() in /org.eclipse.ocl.xtext.oclstdlib/src/org/eclipse/ocl/xtext/oclstdlib/scoping/JavaClassScope.java

Then an M2M to transform the Ecore instance of the Ecore metamodel to the fxml instance of the XML metamodel.

The amount of detail that you require in your Ecore instance model is probably pretty limited, perhaps just EPackage, EClass, EAttribute, EReference; no EOperation, but perhaps you need EGenericType too. It's pretty simple, so faster to code it yourself than struggle to re-use an unfamiliar fuller capability. You could even make it adapt incrementally to classpath changes/rebuilds with moderate effort.

Hi Ed

I haven't yet invested much time in learning Acceleo or epsilon. I accept that Acceleo would probably be easier to learn and use. If you get me the .ecore for javafx (or all of java) I'll give it a try on the weekend.

Best regards,
Henri
