[ATL] Multiple output files with cross-references [message #98689]

Hi,
My problem is this: I have multiple input files (a UML file, an AADL
library (propertysets in aadl)) and i want to create two output files; one
that contains an aadl spec (aadl/core.ecore metamodel) and a second one
that contains an instance of the system designed (instance.ecore
metamodel). Both output models should reference elements from the input
aadl library (for example: i can have an allocation which type is
"actual-memory-binding", this property is defined in the AADL library). So
i have two questions:
1- Can i generate two output files that contain cross-references (elements
in the instanciation model reference elements in the specification model)?

2- Can i reference elements in the aadl library from my output models?

Thanks

You can directly link elements each other, like that :
to {
out1 : SPEC!SpecElement (
),
out2 : SYSTEM!SystemElement (
specelement <- out1
)
}

You must use a special feature provided by ATL execution semantics: in
the matching phase ATL will try to create library elements using a rule,
so you need to set it during the imperative execution phase. For example:
(NOTE: here libElement is a SYSTEM!SystemElement reference pointing to
an element of the input library model)

do {
out2.refSetValue('libElement',<any_library_element>);
}

To do such things, you must check the "allowInterModelReference"
parameter (a VM option).

I tried it, in order to ensure it was working using that parameter :-)
but I found a bug which was disabling the effect of this parameter...

It is now fixed (on CVS head), and the correction will be available on
the next ATL 3.0 build.
Fortunately this will happen next friday at least (Galileo M5 build).
If you can't wait you can use ATL from its CVS source code.

Best regards,

William

You can test both bug 255613 fix and allowInterModelReferences fix using
that build:
