[ATL] ecore to ecore transformation [message #63873]

Hi all,

I'm trying to write my first ATL project using Eclipse 3.3. Here is my
first ATL file :

module ClassModel2DAClassModel; -- Module Template
create da : MOF from dto : MOF;

rule Package{
from
ip :MOF!EPackage
to
op :MOF!EPackage(
name <- ip.name + '.da.hibernate.impl'
)
}

rule Class {
from
ic : MOF!EClass
to
oc : MOF!EClass (
name <- ic.name + 'DAImpl'
)
}

The result is that the packages and the classes are created with the
suffixes I specified.

Example :
- km3 format of my ecore input
package "com.mdd.test" {

class Project {
attribute name[0-1] : ;
attribute beginDate[0-1] : ;
attribute endDate[0-1] : ;
attribute id[0-1] : ;
}
- km3-like format of my ecore output
package "com.mdd.test.da.impl" {

}
class ProjectImpl {
}

So, it's not too bad to begin. The first problem is that my classes are
not in the package. How could I do that in my ATL file?

Then, I would like to add some methods in my MyClassDAImpl like :

public List<MyClass> getAll(){
}

How could I do that?

I will try to read the ATL guide to understand that myself, but I you
can simply explain me the concepts I need to know to do that, it would
really help me.

Thanks for your help.

Regards

Hi Nicolas,

I advise you to take a look to the following article/example:
http://www.eclipse.org/m2m/atl/basicExamples_Patterns/Tree2L ist/
(especially section 6).

Hello,

To link classes with packages, you must create the containment link in
the rule. In your case, you can add a binding in the "Package" rule,
like this :
eClassifiers <- ip.eClassifiers

Then to create an operation in a class, you have to add a binding in the
class to rely the operation, and to describe the operation creation.
Here is an example :

rule Class {
from
ic : MOF!EClass
to
oc : MOF!EClass (
name <- ic.name + 'DAImpl'
)
}
operations <- Sequence{getAllOperation}

and then in the same rule

rule Operation {
from
io : MOF!EOperation
to
oo : MOF!EOperation (
name <- io.name,
parameters <- io.eParameters,
type <- io.eType
)
}

Sorry, I encountered a bug and didn't finish my answer...
:-)

So I wanted to describe the class rule which adds an operation to the
class element :

rule Class {
from
ic : MOF!EClass
to
oc : MOF!EClass (
name <- ic.name + 'DAImpl',
operations <- Sequence{getAllOperation}
),
getAllOperation : MOF!EOperation (
name <- 'getAll'
....
etc...
)
}
