Hello all, i have a problem with this ATL code. The scope of this program is
to derive the references from one class to all subclasses.
Where is the problem?
Is possible to generate an target model with a helper?
Where is the guide to use lazy-rules?
Thanks in advance
Migert Kapaj
create OUT : KM3 from IN : KM3;
helper def: relazioni(inp : KM3!Reference) : Set(KM3!Reference) =
thisModule.all_subclasses(inp.owner)->iterate(iter; acc:
Set(KM3!Reference)=Set{} |
acc->union(Set{thisModule.creaRelazione(inp,iter,inp.type)})
);
rule creaRelazione
{
from rel: KM3!Reference, owner1: KM3!Class, type1: KM3!Class
to relazione : KM3!Reference(
isContainer <- rel.isContainer,
--opposite <- rel.opposite,
name <- rel.name,--.concat(type.name),
location <- rel.location,
lower <- rel.lower,
upper <- rel.upper,
isOrdered <- rel.isOrdered,
isUnique <- rel.isUnique,
type <- type1,
owner <- owner1
)
}
rule CopyReference {
from
s : KM3!Reference(if s.opposite.oclIsUndefined() then
true
else
false
endif
)
to
t : distinct KM3!Reference foreach(c in
thisModule.relazioni(s))--relazioni(s))
(
isContainer <- s.isContainer,
--opposite <- c.opposite,
name <- s.name,
location <- s.location,
lower <- s.lower,
upper <- s.upper,
isOrdered <- s.isOrdered,
isUnique <- s.isUnique,
type <- s.type,
owner <- c
)
}
.... other rules are OK

The problem is that you're trying to call a matched rule (which is not
callable) from an helper (which is not possible). Indeed, the goal of an
helper is to navigate the input model(s) in order to retrieve and/or
compute useful information to be used in the rules which build the
output model elements. Thus, you cannot create output model element from
an helper.

You can find from
http://wiki.eclipse.org/ATL_Language_Troubleshooter#ATL_matc hed.2C_called_and_lazy_rules:_differences
more detailed information on lazy rules and on how to call them.
As lazy rules are also declarative ones, it's recommended using them (if
really needed of course).
Best regards,
Hugo

Hi Hugo, thanks for your answer. The solution of my problem is to use two
foreach statement
foreach( a in thisModule.all_subclasses(source.owner))
for( b in thisModule.all_subclasses(a))
...........
this is possible in atl?
rule CopyReference {
from
s : KM3!Reference(if s.opposite.oclIsUndefined() then
true
else
false
endif
)
to
t : distinct KM3!Reference foreach(c in
thisModule.all_subclasses(s.owner))
for(b in thisModule.all_subclasses(s.type))
(
isContainer <- s.isContainer,
--opposite <- c.opposite,
name <- s.name,
location <- s.location,
lower <- s.lower,
upper <- s.upper,
isOrdered <- s.isOrdered,
isUnique <- s.isUnique,
type <- b,
owner <- c
)
}
Thank you,
Migert
