Hi,

I have some problems to run the EGL Example (org.eclipse.epsilon.examples.egldoc.zip).

I just downloaded the zip file and imported it into a Java Project within Eclipse. But now I have some trouble to solve the import problems.
I added some libraries like
org.eclipse.epsilon.eol.engine.jar
org.eclipse.epsilon.egl.engine.jar
org.eclipse.epsilon.commons.jar
to the build path and changed the imports in the java classes from org.epsilon to org.eclipse.epsilon.
But there is a problem I cannot resolve. In the class EglDocFacade.java (line 69 and 70) I get the following error message
The method getScope() is undefined for the type IEglContext

Have there been any major changes on the interfaces in the last time?
Or do I have to import other libraries to run the example?

Thanks,
Andreas

Hi Andreas,

It appears that we'll need to update this example as there have been a
few changes in the EGL API since we first wrote it. We'll have a look at
this and get back to you.

Cheers,
Dimitris

Hi Andreas,

I've updated the EGLDoc example to work with the latest version of EGL. Would you try downloading the current version?

http://www.eclipse.org/gmt/epsilon/examples/getit.php?exampl e=org.eclipse.epsilon.examples.egldoc

To launch the example, run the EglDoc.launch file in the example directory. This should produce an output directory containing documentation for the example/Families.ecore metamodel.

I'll update the JAR, DOC and PDF files tomorrow.

Cheers,
Louis.

Hi Louis,

thank you for the quick response.

I downloaded the example and now it works fine.

Thanks again,

Hi Louis,

yeah maybe you can help me again.

What do I want to generate with EGL?
I have a trace model (XMI file), which is based on a meta model (ECore file).
Now I want to generate a report based on the data in the trace model. So far I think that should be possible with EGL.
I studied your example a little bit and now I'm trying to implement a small prototype.
My only problem at the moment is, that I have no idea how I can access the data from the trace model in the template files.

Maybe you can give me a hint?

Thanks,
Andreas

... in the meanwhile I moved a step forward.

I made a mistake by the instantiation of the class EmfModel for the trace model. I had set the property READONLOAD to false.
Now I'm able to access the trace model, but only on the meta level (via the allInstances() method).

Is there a possibility to access the correct data from the trace model within my EGL templates?
Can I cast objects in EGL templates?

Thanks,
Andreas

Hi Andreas,

It would probably help if you could provide some more information on
this (metamodels, sample models, what you're trying to generate etc.).

Cheers,
Dimitris

Hi Dimitris,

sure I can provide you some more information.

I have a trace model (xmi file) with was generated during a model to model transformation. Now I want to generate something like a coverage report from that trace model. So I want to read the trace model, calculate some things and then generate a HTML report from this information.
But at the moment, I'm not able to access the concrete data within the trace model. I only can access the meta model level.

How the meta model of the trace model looks like, you can see here:
http://img225.imageshack.us/img225/1724/tracemodel.png

A small version of a concrete trace model could look like this:
http://img843.imageshack.us/img843/5540/tracemodelexamle.png

Till now I haven't found a way to access the attributes like id, name, modelID, ...

I also already sent you my sample project on your GMail account. I hope you received it.

Thanks,

Andreas

Hi Andreas,

I've received your email but haven't had a chance to look at it yet.
I'll hopefully do so and get back to you later on today.

Thanks to Dimitris I'm now able to access the attributes, ...

If you know how it's really easy:

for (l in TraceLink.all) {
out.println(l.id + "<br><br>");
}

Thanks again.

Hi Dimitris,

now I have another problem.
The solution above for accessing the attributes works fine as long as I only have one model.
If I try to load an additional model in my program, I only can access the data the way above for the model which I loaded first. For the second model I get the following exception:

Exception in thread "main" Type 'Package' not found (...)
at org.eclipse.epsilon.egl.internal.EglPreprocessorModule.execu te(EglPreprocessorModule.java:64)
at org.eclipse.epsilon.egl.internal.EglModule.execute(EglModule .java:143)
at org.eclipse.epsilon.egl.internal.EglModule.execute(EglModule .java:153)
at org.eclipse.epsilon.egl.EglTemplate.process(EglTemplate.java :69)
at org.epsilon.egl.doc.EglDocFacade.generate(EglDocFacade.java: 90)
at org.epsilon.egl.doc.EglDoc.main(EglDoc.java:26)

Is it not possible to use several input models with EGL? Or do I have to consider something special?

Kind regards,

Andreas

Hi Andreas,

When you have more than one models in your Epsilon programs you should
use the ModelName!ClassName syntax to distinguish between meta-classes
in your models.

Dimitris
