Hi,
I have defined an ATL module that suprisingly produces a new kind of models. In fact after execution I get a model that is not conform to it's metamodel !
My taget metamodel is ComGraph.ecore and this it's Emfatic description:
class ComGraph {
val Element[*] elements;
}
class Element {
attr String name;
}
class Node extends Element {
}
class Link extends Element {
ref Node source;
ref Node target;
}
My source metamodel is Scenario.ecore:
package Scenario;
import "platform:resource/diagnostic_SGS/metamodel/IFConfiguration.ecore";
class Scenario extends IFConfig.NamedElement{
val IFConfig.Transition[*] firedTransitions;
}
And it is using a metaclass from the IFConfiguration.ecore :
@namespace(
uri="http://irit.fr/ifconfiguration",
prefix="ifconf")
package IFConfig;
...
class Transition {
val Action[*] actions;
attr Integer number;
}
class Action {
attr String kind;
}
...
So the following transformation should create a ComGraph model:
-- @path ComGraph=/diagnostic_SGS/metamodel/ComGraph.ecore
-- @path Scenario=/diagnostic_SGS/metamodel/Scenario.ecore
module Scenario2ComGraph;
create OUT : ComGraph from IN : Scenario;
rule Scenario2ComGraph {
from
sS : Scenario!Scenario
to
tC : ComGraph!ComGraph (
elements <- sS.firedTransitions
)
}
rule Transition2Element {
from
sT : Scenario!Transition
to
tC : ComGraph!Element (
name <- sT.actions->first().kind
)
}
BUT after the execution I found my self with a surprising model with elements from both target AND SOURCE metamodel:
<?xml version="1.0" encoding="ISO-8859-1"?>
<comgraph:ComGraph xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:comgraph="http://irit.fr/comgraph" xmlns:ifconf="http://irit.fr/ifconfiguration">
<elements xsi:type="ifconf:Transition" number="1">
<actions kind="DEBUG" value="402">
<by name="Properties_p0"/>
</actions>
<actions kind="DEBUG" value="428">
<by name="Properties_p0"/>
</actions>
</elements>
</comgraph:ComGraph>
As you can see the ComGraph has elements of type Transition wich is not consistent with the ComGraph metamodel.
This my Eclipse configuraiton:
