[ATL] Problem with stereotypes property with several values [message #96833]

Hi all,

I use this helper to get the value of the stereotypes property

helper context UML!"uml::Class" def: getTagValue(stereotype :
String ,tag : String) : String=
self.getValue(self.getAppliedStereotype(stereotype),tag);

It works fine if the property has only one value, but if it has more than
one array of string it can work if I specify the first or last element
in the array. But I need to iterate over all the values in the array and
see if a specific value is exist. I tried to use for or iterates(),
but it didnt work!

Any help is greatly appreciated,

Rasha

Hi i don't understand your question
what you want is not a select ?

myCollec->select(s | s = ...)

I try to copy a class according to the value of its stereotypes property.
There is no problem if the property has only one value. But if it has more
than one value, I want to check if a specific value exists among these
values.

Property = [value_1, value_2, value_3]
If Property has value_2, Ill copy this class.

The getValue() method returns in this case a sequence of value. I want to
iterate over this sequence to check if value_2 exists.

In another word, I need to iterate over the result of this method
self.getValue(self.getAppliedStereotype(stereotype),tag)

I tried to use self.getValue(self.getAppliedStereotype(stereotype),tag)->
select(c | c = 'value_2')but it didn't create a target model and didn't
raise any errors.

Thanks Tristan for your help,

Rasha

did you try to do debug() after your select maybe you should do a
first() after the select to specify that you want a value and not a
selection

self.getValue(self.getAppliedStereotype(stereotype),tag)
==> sequence
self.getValue(self.getAppliedStereotype(stereotype),tag)->select(c | c =
'value_2')
==> sequence
self.getValue(self.getAppliedStereotype(stereotype),tag)->select(c | c =
'value_2')->first()
==> value

Thanks Tristan a lot. I have another question for the Lazy rule. You said
that object is created once even I match it several times. I try to copy
the association between 2 classes, but I have to call the lazy rule which
copy the association twice from the Property rule because each association
has two properties.

rule Property{
from
s : UML!Property
to
t : UML!Property (
name <- s.name,
association <- thisModule.CopyAssociation(s.association) )

}
lazy rule Association{
from
s : UML!Association
to
t : UML!Association (
name <- s.name
)
}
It raise this error
message: trying to register several rules as default for element
IN!Cource-Student: 'CopyAssociation' and 'CopyAssociation'

is this because I called it twice? what did I miss here?

Thanks so much for your help,

Rasha

Hi Rasha this message said that you have two rules able to manage the
object which is not permitted in ATL check that you don't have 2 from
able to match your association in standard rules

and it's strange that you call your lazy rule with this instruction
thisModule.CopyAssociation(s.association) while your lazy rule is
called Association maybe you should use :
thisModule.Association(s.association)

for the fact that object is created once i said the object is created
once for one object matched with unique lazy rule maybe your lazy rule
should be like this :
unique lazy rule Association{
from
s : UML!Association to
t : UML!Association (
name <- s.name
)
}

in fact i've never used "unique" lazy rule :p

Thanks Tristan for this magic word unique. It works fine. Im trying now
to compare between two transformation files doing the same job but one has
to be faster than the other in producing the target model. Is there any
way to measure the time taken by the engine to do that? Something similar
to the time function in C language.

Hi Rasha
One of my friend have designed a ATL profiler to profile ATL
transformations. The ATL team should have this contribution but i don't
know if it will be integrated a day.

Maybe some Obeo's member could answer ...

Hello,

The profiler contribution is still here:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=230906 and should be
compatible with the ATL 2.0 maintenance builds (and 2.0.0 release).

As we recently change a lot of things in the architecture, we were not
able to directly integrate that great contribution... but we are going
to work on it. In the best case it will be integrated in the next ATL
release (Galileo version).

Best regards,

William

to obtain the time an ATL transformation takes to execute you can check
the "print execution times..." in the advanced tab of the ATL run
configuration.
