Hi all,
I have this km3 classes:
class ServiceCall extends Activity {
reference calledService[0-1] : Service oppositeOf serviceCall;
}
class State {
attribute name[0-1] : String;
attribute refersTo: String;
}
now I need to modify this rule:
rule activity2state
{
from
astep: Klaper!Activity (astep.internalFailProb='0')
using{
list: Sequence(Klaper!Behavior) = astep.getSCBehaviorType();
}
to
state: DTMP!State (name<-astep.name,
refersTo<-'TEST',
dtmp<-thisModule.resolveTemp(astep.behavior,
'dtmp'),
}
because I want to write inside the refersTo variable the value of the
reference calledService. How can I do this?
Thanks to all
Best regard
Nicola D'Orazio

Hi,
Since your rule transforms an Activity and not a ServiceCall, you cannot
do astep.calledService. You should do this in a rule matching a ServiceCall.
If you use ATL 2006 (see http://wiki.eclipse.org/index.php/ATL_2006),
then you can use rule inheritance:
rule ServiceCAll2State extends activity2state {
from
astep : Klaper!ServiceCall
to
state: DTMP!State (
refersTo<- astep.calledService
)
}
If you do not want to use ATL 2006 or rule inheritance, then you will
have to modify your rule after having copied and pasted it if you want
to keep a rule matching activities.
