Hello,

I am beginner with ATL. I would like to tranforme a Class with property to a other Class with same properties and 2 operations corresponding to the setter and getter of the properties.
I work with UML2 metamodel for the IN and OUT model.

I arrive to generate the properties inside the target Class but the operations don't inside the the target class.



My ATL code :
-- @path UML2=platform:/plugin/org.eclipse.uml2.uml/model/UML.ecore

module persistence;
create OUT : UML2 from IN : UML2;

helper context String def : firstUpper() : String =
self.substring(1, 1).toUpper()+self.substring(2,self.size());

rule dao {
from a:UML2!Class
to d:UML2!Class (
name <- a.name +'DaoImpl',
ownedAttribute <- a.ownedAttribute->select(sf | sf.oclIsKindOf(UML2!Property)
)
)
}
rule attribute {
from a:UML2!Property
to p:UML2!Property (
name <- a.name,
owner <-a.owner),
get:UML2!Operation (name <- 'get'+a.name.firstUpper()),
set:UML2!Operation (name <- 'set'+a.name.firstUpper())
}



The model generated :
<?xml version="1.0" encoding="ISO-8859-1"?>
<xmi:XMI xmi:version="2.1" xmlns:xmi="http://schema.omg.org/spec/XMI/2.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:uml="http://www.eclipse.org/uml2/3.0.0/UML" xsi:schemaLocation="http://www.eclipse.org/uml2/3.0.0/UML platform:/plugin/org.eclipse.uml2.uml/model/UML.ecore">
<uml:Class xmi:id="_BbNQpDWzEd-NCLTv9ULYUg" name="DepartementDaoImpl">
<ownedAttribute xmi:id="_BbNQpTWzEd-NCLTv9ULYUg" name="property1"/>
</uml:Class>
<uml:Operation xmi:id="_BbNQpjWzEd-NCLTv9ULYUg" name="getProperty1"/>
<uml:Operation xmi:id="_BbNQpzWzEd-NCLTv9ULYUg" name="setProperty1"/>
</xmi:XMI>

see Public To Private Example

getter : UML!Operation (
name <- 'get'+publicAttribute.name.toU1Case,
class <- publicAttribute.refImmediateComposite(),
type <- publicAttribute.type
),

Create a called rule which gives you a set of operations (your 2
accessors) for a property and add this set to the classe operations set.
Be care that in ATL the Union method on sets return a copy of the set so
you must reaffect the result to the class:
ownedOperation <- ownedOperation->union(yourCalledRule(xxx))

Hello,

Thank you for the answers.

Vincent, I have try your solution, but i have a error.
It doesn't find a operation.
Have you got a idea for the solution ?
Thank.


see the error message bellow :
Operation not found: OUT!property1:UML2!Operation.not()
at __applydao(persistence.atl[14:21-14:75])
	local variables: self=thisModule, link=org.eclipse.m2m.atl.engine.emfvm.lib.TransientLink@166aa35, a=IN!Departement:UML2!Class, d=OUT!DepartementDaoImpl:UML2!Class, sf=IN!property1:UML2!Property
at __exec__(persistence.atl)
	local variables: self=thisModule, e=org.eclipse.m2m.atl.engine.emfvm.lib.TransientLink@166aa35
at main(persistence.atl)
	local variables: self=thisModule


see the code of my transformer :

module persistence;
create OUT : UML2 from IN : UML2;

helper context String def : firstUpper() : String = 
	self.substring(1, 1).toUpper()+self.substring(2,self.size());

rule dao {
	from a:UML2!Class
	to  d:UML2!Class (
		name <- a.name +'DaoImpl',
		ownedAttribute <- a.ownedAttribute->select(sf | sf.oclIsKindOf(UML2!Property)),
		ownedOperation <- a.ownedOperation->union(a.ownedAttribute->select(sf | thisModule.accessor(sf)))
		)
}

lazy rule accessor {
	from a:UML2!Property
	to o:UML2!Operation (name <- a.name)
}


Cordialement,

ownedOperation <- a.ownedOperation->union(a.ownedAttribute->collect(sf | thisModule.accessor(sf)))

BTW you can keep a declarative mode by using resolveTemp :

rule attribute {
from a:UML2!Property
to p:UML2!Property (
name <- a.name,
owner <-a.owner),
get:UML2!Operation (name <- 'get'+a.name.firstUpper()),
set:UML2!Operation (name <- 'set'+a.name.firstUpper())
}

ownedOperation <- a.ownedOperation->union(a.ownedAttribute->collect(sf | Sequence{thisModule.resolveTemp(sf,'get'),thisModule.resolve Temp(sf,'set')})- >flatten())

This solution is too difficulte for me.
I'm a begginer

I have to work on the doc before understand this kind of code.
but there isn't lot of tuto for ATL.

Thanks again.
