[ATL] MoDisco .javaxmi files [message #656618]

Hi!

I am working on a Modeling Project with MoDisco with the full workflow from Reverse Engineering to M2M to Forward Engineering.

I retrieve a Model from an application with MoDisco Discoverer which results in a x.javaxmi file.

For platform independence i want to transform this model in a PIM model but within the same metamodel (java.xmi or ecore?) but with less information.

I did some UML transformation earlier and I remember that I got a copy of the source model when I startet the ATL Transformation with an empty atl-file (without any rules).

I wanted to test the atl-file for the javaxmi transformation now without any rules but I keep getting an empty result file.
Is there any special meta model definition to use with the javaxmi transformation?

I am using: http://www.eclipse.org/MoDisco/Java/0.2.incubation/java for the uri.

Many thanks in advance

Hello George,

I'm not aware of the "empty atl-file" but working on a project this period, I found something that could be useful in your case...

It's an atl transformation file that produces atl code for coping any model you want....

Thx 4 your answer, Thanasis.

I was able to solve this problem. It was just a mistake with from/refine keyword in atl module.

But anyway I am running into some strange problems.

Still on javaxmi model based on java.ecore doing transformation from java to java - same metamodel.
I tried to create lazy rules to transfer type information from FieldDeclarations and Parameters, which works so far.

lazy rule F2F {
	from
		s: Java!FieldDeclaration
	to
		t : Java!FieldDeclaration (
			type <- thisModule.TA2TA(f),
		)
}

lazy rule TA2TA {
	from
		f: Java!TypeAccess
	to
		t : Java!TypeAccess (
			type <- if (f.type.type.oclIsKindOf(Java!PrimitiveTypeVoid))
.....

I am not quite sure, why I have to access type twice here - but this way the checks work - although I can not figure it out from the metamodel. From my understanding it should work with f.type.olcIsKindOf ...

the same code works for Parameters (i.e. SingleVariableDeclarations)

but when I try to transfer returnType in MethodDeclaration I get an error, that type is not valid for MethodDeclaration.

Maybe I am missunderstanding some concepts of ATL. But I dig through the Metamodel and from my point of view it should not matter whether it is type in SingleVariableDeclaration/AbstractVariablesContainer or returnType in MethodDeclaration.

Any hints would be appreciated.

Thx
Rob
