Hi.

I am a beginner in Acceleo and have a "simple" problem.

I write this code:

primeiraOrdem(Conceito, Consulta) :-
[for (elemento : Componentes | aMapaConceitual.elementos->sortedBy(descricao))]
	[if (elemento.oclIsTypeOf(Relacao))]
	[elemento.descricao/](Conceito, Consulta),
	[/if]
[/for]

And i get this results:

primeiraOrdem(Conceito, Consulta) :-
	e(Conceito, Consulta),
	podeestar(Conceito, Consulta),
	podeser(Conceito, Consulta),
	quandoesta(Conceito, Consulta),
	quandoesta(Conceito, Consulta),
	tem(Conceito, Consulta),
	tem(Conceito, Consulta).

My question is: "How can I remove the lines that are worded "duplicate" (case of 'quandoesta' and 'tem')?"

I tried everything I could think but not got successful.

Excuse my poor English.

Thank you already.

Hi

Set is the usual way to force uniqueness, with isUnique() helpful in
more complicated scenarios.

You can just change to loop over your names reduced to a set of their values

[for (descricao: String|
aMapaConceitual.elementos->select(oclIsTypeOf(Relacao)).descricao->asSet()->sortedBy(descricao
| descricao))]
[descricao/](Conceito, Consulta),
[/for]

oclIsKindOf is generally better than oclIsTypeOf, in which case filter()
would be better. (In Juno OCL adds selectByType and selectByKind as well).

Thank you so much.

It worked perfectly.

I tried using the "asSet" but with a collection of "Relacao" and not their "descricao".

Now I understand how to use it.

I'm very grateful for your help!
