Hi,
I would like to write a generic rule that calls a helper that computer the
type of the metaclass that will be generated, i wrote this code (that
doesn't work):

helper context UML2!Class def : GenericComponentName () :
AAXL!ComponentClassifier =
if self.isStereotypeApplied('MemoryPartition') then
AAXL!MemoryType
else if self.isStereotypeApplied('SwSchedulableResource') then
AAXL!ProcessType
else
AAXL!ComponentClassifier
endif
endif ;

rule ClassGeneric {
from a: UML2!Class (a.isAbstract())
--ERROR HERE-- to p: oclType(a.GenericComponentName())(name <- a.name)}

It seems that this is impossible to do this way because of the way ATL
computes the atl transformation file, does anybody have an idea of how to
do this?

Hello,

The "to" part of the rule can't be parametrized, you need to do that in
another way. For instance :

rule Class2MemoryType {
from a: UML2!Class (
a.isAbstract() and a.isStereotypeApplied('MemoryPartition'))
to p: AAXL!MemoryType ()
}

rule ClassGeneric {
from a: UML2!Class (
a.isAbstract() and a.isStereotypeApplied('
etc...

Best regards,

William
