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
