Hi,
Trying to do a very basic transformation using QVT, but doesn't work.
My ecore model is :
<?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="myDsl"
nsURI="http://www.xtext.org/example/mydsl/MyDsl" nsPrefix="myDsl">
<eClassifiers xsi:type="ecore:EClass" name="Namespace">
<eStructuralFeatures xsi:type="ecore:EReference" name="elements" upperBound="-1"
eType="#//ModelElement" containment="true"/>
</eClassifiers>
<eClassifiers xsi:type="ecore:EClass" name="ModelElement">
<eStructuralFeatures xsi:type="ecore:EReference" name="case" eType="#//Case" containment="true"/>
</eClassifiers>
<eClassifiers xsi:type="ecore:EClass" name="Case">
<eStructuralFeatures xsi:type="ecore:EAttribute" name="name" eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EString"/>
</eClassifiers>
</ecore:EPackage>
& instance file is :
<?xml version="1.0" encoding="UTF-8"?>
<myDsl:Namespace xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:myDsl="http://www.xtext.org/example/mydsl/MyDsl">
<elements>
<case name="Name">
</case>
</elements>
</myDsl:Namespace>
QVT file is as:
modeltype myDslTransform uses "http://www.xtext.org/example/myDslTransform/myDslTransform";
modeltype myDsl uses "http://www.xtext.org/example/mydsl/MyDsl";
transformation NewTransformation(in source:myDsl,out target:myDslTransform);
main() {
source.rootObjects()[Namespace] -> map NamespaceToNS();
log("comes here in main " );
}
mapping Namespace::NamespaceToNS():myDslTransform::NS{
log("NamespaceToNS " + self.metaClassName() );
self.subobjects() -> map ModelElementToME();
}
But the above thing does not work. It does not traverse to the mapping NamespaceToNS().
But if write the QVTo file like as below then it works & traverse through the next mapping but then it wont solve the purpose.
The log statement self.metaClassName() gives Namespace. But then not sure what the problem is?
main() {
source.rootObjects()[Element] -> map NamespaceToNS();
log("comes here in main " );
}
mapping Element::NamespaceToNS():myDslTransform::NS{
log("NamespaceToNS " + self.metaClassName() );
self.subobjects() -> map ModelElementToME();
}
Thanks
Vishal
