Hi,
I wish to add elements of a model into another which is a kind of
repository. To do that,I made a transformation which creates the target
model elements I need, and programmatically, I launch my transformation
using as target model the existing model instead of a new model
(depending on the model already exists or not) !
######## transformation header #######
-- @atlcompiler atl2004
module saveil;
create OUT : asurIL refining IN : asurIL;
######## my code ########
ASMModel outputModel = null;
ASMModel inputModel =
emfamh.loadModel("IN" ,asurilMM_EMF,domainModelPath.toFile().toURI().toURL().openS tream());
if (domainProject.exists(new Path(".components"))) {
outputModel =
emfamh.loadModel("OUT",asurilMM_EMF,domainProject.getFile( ".components").getContents());
} else {
outputModel = emfamh.newModel("OUT", asurilMM_EMF);
}
Map models = new HashMap();
models.put(asurilMM_EMF.getName(), asurilMM_EMF); // input metamodel
models.put(asurilMM_EMF.getName(), asurilMM_EMF); // output metamodel
models.put("IN", inputModel); // input model
models.put("OUT", outputModel); // output model
AtlLauncher.getDefault().launch(saveilURL,Collections.EMPTY_ MAP,models,Collections.EMPTY_MAP);
emfamh.saveModel(outputModel,".components", domainProject);
########################
I try to use the refining mode for this transformation.
It works fine if the target model is new but it generates an exception
if I use the existing model :
"java.lang.IllegalArgumentException: argument type mismatch"
NativeOperation public static void
org.atl.engine.vm.nativelib.ASMTransientLink.addTargetElemen t(org.atl.engine.vm.StackFrame,org.atl..engine.vm.nativelib. ASMTransientLink,org.atl.engine.vm.nativelib.ASMString,org.a tl.engine.vm.nativelib.ASMOclAny)
args = [TransientLink {rule = 'MODEL', sourceElements = {input =
IN!<unnamed>}, targetElements = {}, variables = {}}, TransientLink {rule
= 'MODEL', sourceElements = {input = IN!<unnamed>}, targetElements = {},
variables = {}}, 'output']
Refining mode or normal mode, the error is the same !
Is it possible to do what I want ?
Maybe, using 2 source models, one to refine with the content of the
second ? How to do that ?
Many thanks !
Guillaume

Sorry, I think I have found the solution be using 2 input models,
creating a target model which merge the 2 input

I finally get what I want, a model 'MERGE' which merge the content of a
repository 'COMP' + content of a new model 'IN' !
It works fine launching the transformation using Eclipse Run Dialog
But its behavior changes when launching it programmatically !
The transformation is first copying content of repository model into the
output model by using an entrypoint. All components are copying, and
other matched rules will put into the output model, new elements using
some constraints !
If you look to the entrypoint below, I have put some debug information
about the components I want to copy into the output model :
there is 2 strange things
- launching programmatically, the number of components inserted in the
merge model is 0 (thisModule.mergeModel.components->size()) so, in that
case, the assignment 'model.components <- oldmodel.components' doesn't
seem to work !
- using the eclipse running dialog, the set of components get with
'asurIL!Component.allInstancesFrom('COMP')' is empty, and using the
helper compFromRep, it works fine !
Here is the two strange things I don't understand. I insert below the
launching java code I used, maybe I do something wrong here.
Thank you for your interest
