Hi everyone,
I need to convert Ecore models to their equivalent representation in UML. For that purpose I'm trying to use the atl script in the following link (http://emftriple.googlecode.com/svn/tags/0.6.1/com.emf4sw.uml/src/com/emf4sw/uml/resources/Ecore2UML.atl).
It works fine with the exception of not setting the types of UML Properties. I've allowed inter-model references and then I got the following exception which I understand but do not know how to fix:
org.eclipse.emf.ecore.impl.EDataTypeImpl cannot be cast to org.eclipse.uml2.uml.Type
which is caused by this rule:
rule EAttribute2Property {
from e: Ecore!EAttribute
to
u: UML!Property (
name <- e.name,
type <- e.eType,
upper <- e.upperBound,
lower <- e.lowerBound
)
}
I understand that an ecore type cannot be directly mapped to a UML type. What I need is a function that checks the ecore type and then returns the corresponding UML primitive type.
I've tried the following test, but since I do not have the UML primitive types loaded it does not returns nothing:
type <- UML!PrimitiveType.allInstances() -> select(e | e.name = 'String').first()
In addition, I know that the destination model (UML) must contain the following XML in order to import the UML primitive types:
<packageImport xmi:id="_ZhW94SBFEeO_m-zgIyufMQ">
<importedPackage xmi:type="uml:Model" href="pathmap://UML_LIBRARIES/UMLPrimitiveTypes.library.uml#_0"/>
</packageImport>
Can anyone help me with this?
Thanks in advance!

I solved this issue last week by importing the model with the UMLPrimitiveTypes and then I've defined a helper that receives the Ecore type and return its corresponding UML type.
helper def : getMappingType(input : Ecore!ETypedElement) : UML!Type =
if(input.name = 'EString') then Library!PrimitiveType.allInstancesFrom('IN_Library')->any(e|e.name='String')
else if(input.name = 'EBoolean') then Library!PrimitiveType.allInstancesFrom('IN_Library')->any(e|e.name='Boolean')
else if(input.name = 'EInt') then Library!PrimitiveType.allInstancesFrom('IN_Library')->any(e|e.name='Integer')
else if(input.name = 'EDouble') then Library!PrimitiveType.allInstancesFrom('IN_Library')->any(e|e.name='Real')
else OclUndefined
endif endif endif endif;
rule EAttribute2Property {
from e: Ecore!EAttribute
to
u: UML!Property (
name <- e.name,
type <- thisModule.getMappingType(e.eType),
upper <- e.upperBound,
lower <- e.lowerBound
)
}
Thanks anyway!
