[ATL] Can input model variables be referred to in rules? [message #105367]

Hi,

I defined a module as follows:

module Test;
create OUT : UML from IN1 : UML, IN2: UML, PROFILE: UML;
...

Later in the implementation of a rule I would like to refer to the PROFILE
input model, as follows for instance:

rule Rule1 {
from e: UML!Class ((sys.oclIsTypeOf(UML!Class)) and
(sys.getModel().equals(thisModule.PROFILE))
...

This code has no compilation error, but at run time I get the following
output:

INFO: Execution terminated due to error (see launch configuration to allow
continuation after errors).
GRAVE: transformation module "Test" does not have an initialized field
named "PROFILE"
java.lang.RuntimeException: transformation module "Test" does not have an
initialized field named "PROFILE"

Any tip on how I can use the input model variable??

Thanks in advance
Agustina

Maybe like this:

rule Rule1 {
from e: UML!Class, p: PROFILE!Profile ((e.oclIsTypeOf(UML!Class)) and
(e.getModel().equals(p.name)) ...

Hi again, sorry, I pressed 'Post' too quickly.

The solution that you propose does not work. PROFILE is not a metamodel
but a variable that refers to an input model that complies with the UML
metamodel.

What I actually need to do in my rule is to check that the class that is
matched in the variable e belongs to the input model PROFILE (PROFILE is a
input variable that refers to such a model)...

I am pasting here again what I would like to be able to write (without
copy/paste errors now):

rule Rule1 {
from e: UML!Class ((e.oclIsTypeOf(UML!Class)) and
(e.getModel().equals(thisModule.PROFILE)) ...

Thanks!
Agustina

try this :

module Test;
create OUT : UML from IN1 : UML, IN2;
...

helper def : profileName : String = 'yourProfileName'

....
rule Rule1 {
from e: UML!Class ((sys.oclIsTypeOf(UML!Class)) and (not
(sys.getAllAppliedProfiles()->select(p | p.name =
thisModule.profileName)->isEmpty())

sorry, you have to get the model of the class first:

....
rule Rule1 {
from e: UML!Class ((sys.oclIsTypeOf(UML!Class)) and (not
(sys.getModel().getAllAppliedProfiles()->select(p | p.name =
thisModule.profileName)->isEmpty())
