[ATL] Register ATL metamodel in EMF Registry [message #103834]

Hi,
I want to use the ATL metamodel to launch a high order transformation
where i will modify an ATL model. The problem is that the ATL metamodel
uri is not registered in he EMF registry so i cannot select it in the run
configuration window, i also want to use the ATL metamodel uri
programmatically in the launch method.
The question is, how can i programmatically register the ATL metamodel in
the EMF registry from the ATL .jar files?

I tried to uncompress the atl.ecore metamodel from the .jar then i
generated the code with EMF, then i delivered it in a new feature, but
this causes some problems as there will be two diffrent implementations of
the metamodel that are not "equal".

I'm using ATL3
Thanks

Hello,

Since ATL 3.0, you can use a platform:/plugin... or
platform:/resource... uri. So for ATL, you can use:
platform:/plugin/org.eclipse.m2m.atl.common/src/org/eclipse/ m2m/atl/common/resources/ATL.ecore
in the launch configuration.

Best regards,

William

thanks william, your solution worked and saved me a lot of time.

i also had to register the EPackges programmatically using this:

EMFModelLoader emfLoader = (EMFModelLoader) modelLoader;
Iterator<ASMEMFModelElement> it =
inMM.getElementsByType("EPackage").iterator();
while ( it.hasNext() ) {
EPackage ePackage = (EPackage) it.next().getObject();
emfLoader.getResourceSet().getPackageRegistry().put(
ePackage.getNsURI(), ePackage );

Skander,

You may be able to use the extension point

org.eclipse.emf.ecore.dynamic_package in your plugin.xml to

avoid programmatically doing this.

William, I see that the code for org.eclipse.m2m.atl.drivers.emf4atl has

this present but commented out on the grounds that it is EMF 2.4 specific.

Can it not be enabled for the ATL 3.0.0 codebase?

Andy.
