Hi,

I have a ATL transformation which take one input and produce in output
one ATL transformation (High Order Transformation), it works fine with
ATL 3.0 (tested with Galileo M7).
Now I want execute this output ATL transformation, but this output is in
XMI format, then my first question is, can I execute directly my ATL
transformation in XMI format and how?

If not possible, I could transform my XMI format in concrete syntax to
execute a .atl. With TCS I could do it, but I don't find TCS source code
repository. What is the status of TCS, what is the project plan. And
what is TCS compared to TMF Xtext from oAW?

I found AMW project from GMT which use HOT transformation, but it
doesn't works and I don't understand these sources.

Thanks.

At this time you can't.

ATL 3.0 API provide utilities to:
- output ATL source code from an ATL model
* org.eclipse.m2m.atl.engine.parser.AtlParser
* available within ATL ant tasks, use "ATL" extractor
- create an ATL model from ATL source code
* org.eclipse.m2m.atl.engine.parser.AtlParser
* available within ATL ant tasks, use "ATL" injector
- compile ATL source code to an ASM file/outputstream
* org.eclipse.m2m.atl.engine.compiler.AtlCompiler
- compile an ATL model to an ASM file/outputstream
* org.eclipse.m2m.atl.engine.compiler.AtlDefaultCompiler

> Thanks.

Best regards,

William

Hi William,

To begin my HOT transformation I would like to create a simple rule :

rule getEntity2ValueObject {
from
entitySource : UML!Class (
entitySource.getAppliedStereotypes()->exists(e|e.name='Entity')
)
to
entityTarget : UML!Class (
)

To do that I have the joined mapping2ATLBis.atl which use
OperationCallExp and StringExp respectively to '=' operator and to
'Entity' expression. The problem when my HOT transformation is executed
is that is get the following ATL code :

rule Entity2ValueObject {
from
entitySource : UML!Class
(
entitySource.getAppliedStereotypes()->exists(e |
e.name.'='('Entity')
)
)
to
entityTarget : UML!Class
}

which isn't syntactically correct. What is my mistake?
It's too hard to debug in PrettyPrinter and finally I don't understand
why these characters are appended.
My purpose it to reproduce Business2TechnicalM2M.atl joined code;
To help my HOT writing I use XMI version of Business2TechnicalM2M.atl to
see what ATL.ecore EClass to use.

About ATL.ecore, LocatedElement has a location EAttribute which concerns
ATL syntactic sugar, that's right? If right why this appears in metamodel?

Last question :
How can I assign
pathmap://UML_LIBRARIES/UMLPrimitiveTypes.library.uml#string to a target
UML!Parameter?
I must probably use a appropriate input but how to reference String type?

Thanks.

It's a mistake in my HOT ATL transformation, I have confused
OperationCallExp and OperatorCallExp.
