I'd recommend create an EOperation in your metamodel and implement it in Java. You can then use it in your ATL program.

rule rule_getHeadModule{
from
b:source!ModuleItem

to
d:target!HeadModule(
deviceID<-b.IdentNumber,
s7ModuleReference <- b.ModuleReference,
isSelectedWithinStep7<-b.IsSelected
)

}

IdentNumber is string which has hex value. deviceID is int. if i have hex2Int(String str) at target!HeadModule, how can i call that to above rule?

thanks
K

lazy rule rule_getModule{

to
d:target!Module(
deviceID<- d.hexToInt(b.IdentNumber),
s7ModuleReference <- b.ModuleReference,
isSelectedWithinStep7<-b.IsSelected

I get an error:

at rule_getHeadModule#28(TPF2PSSu2.atl[95:16-95:46])

any solution?

Thanks.

here is the issue:

helper context source!ModuleItem def : getIdentNumber():
String = self.ParameterList.ParameterItem->select(pi |
pi.Name='IdentNumber')->collect(e|e.Value)->first();

lazy rule rule_getModule{
from
b:source!ModuleItem

to
d:target!Module(
deviceID<-d.hexToInt(b.getIdentNumber()),
s7ModuleReference <- b.ModuleReference,
isSelectedWithinStep7<-b.IsSelected
)

}

Error comes at the deviceID line as:

org.eclipse.m2m.atl.engine.emfvm.VMException: Operation not found: OUT!<unnamed>.hexToInt(java.lang.String)
at rule_getModule#28(TPF2PSSu2.atl[81:16-81:46])
local variables: self=TPF2PSSu2 : ASMModule, b=IN!<unnamed>, d=OUT!<unnamed>

any help is appriciated.

Thanks

are you using the EMF version as the meta-model instead of the ecore file ?

Or this might be because d is not already a target!Module in which case you could try to do the line in the "do" section :

lazy rule rule_getModule{
from
b:source!ModuleItem
to
d:target!Module(
s7ModuleReference <- b.ModuleReference,
isSelectedWithinStep7<-b.IsSelected
)
do{
d.deviceID<-d.hexToInt(b.getIdentNumber());
}
}

Hi Sylvain,

Thanks a mil for ur help.

I have set ecore files at the run configuration.

How to set the EMF version as the meta-model instead of the ecore file?

Thanks in advance

what do u mean?

At run configuration, I have set source.ecore and target.ecore files. How can i set EMF version as the meta-model instead of the ecore file ?

Thanks.

Use the URI of the meta-model and not the physical .ecore file.

Hi Sylvain,

metamodel is model.ecore,which is saved in c:\temp\ .

<?xml version="1.0" encoding="UTF-8"?>
<ecore:EPackage xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" name="model"
nsURI="model" nsPrefix="">

----

</ecore:EPackage>

how to get the URI of this meta model, which I need to set up at run configuration?

Thanks a million.
Kosala

I setup target meta model as nsURI="model".
Now i get an error:

Error loading platform:/resourcensURI="model": java.net.MalformedURLException: Invalid URL "platform:/resourcensURI="model"".

any clue on this?

Thanks.

Thanks.

My problem is, yes I defined EOperation (hexToInt(String)) signature at target.ecore diagram, however the EOperation is implemented at the code base, which is generated from the target.genmodel.

How to call this hexToInt() in my ATL module? This is my problem.

Can I use run configuration settings to call this operation? I do not think so, because run configuration is not linked with generated code. (is there any way to make that link?)

As the other option,
I created an ATL plugin, and trying to run as a java application.

Properties file:
# Metamodels paths or nsUris
TPF2PSSu2.metamodels.source = file:/C:/..../source.ecore
TPF2PSSu2.metamodels.target = file:/C:/.../target.ecore

loading models:

/**
* Load the input and input/output models, initialize output models.
* @generated
*/
public void loadModels(String inModelPath) throws ATLCoreException {
ModelFactory factory = new EMFModelFactory();
IInjector injector = new EMFInjector();
IReferenceModel sourceMetamodel = factory.newReferenceModel();
injector.inject(sourceMetamodel, getMetamodelUri("source"));
IReferenceModel targetMetamodel = factory.newReferenceModel();

injector.inject(targetMetamodel, getMetamodelUri("target"));
this.inModel = factory.newModel(sourceMetamodel);
injector.inject(inModel, inModelPath);
this.outModel = factory.newModel(targetMetamodel);
}

I still get the error:

org.eclipse.m2m.atl.engine.emfvm.VMException: Operation not found: OUT!<unnamed>.hexToInt(java.lang.String)
at rule_getModule#40(TPF2PSSu2.atl[87:15-87:45])

Yes, I can understand, this launcher is not yet connected with the generated code.

Is there any approach to load the target meta model from the generated code?

It looks to me some modification is needed at
injector.inject(targetMetamodel, getMetamodelUri("target"));
this.inModel = factory.newModel(sourceMetamodel);

I really appriciate any help to solve this problem.

Thanks
Kosala
