[Acceleo 3] write all the imports of a class [message #554861]

Hi,

I wanna write all the imports of a class, so I want to get all the classes included in the parameters of the operations.

I tried this:

[query public getParametersOperations(class : Class) : Sequence(T) =
class.getAllOperations().parameterableElements()->select(not oclIsKindOf(Class))/]

[template public importBlock(class : Class)]
// [protected ('for imports')]
[for (at : Parameter | class.getParametersOperations())]
import [packageDomain(class) + at.type.name /];
[/for]
// [/protected]
[/template]

but If the same class is in more than one parameter, I've got a repeated import.

I want to use this in more than one place...
How can I filter the correct classes? Or you know another way to do that?

THANK YOU!!

Hi,

The key in your problem here is to use asSet() which will transform your collection into a Set. Because a set cannot have a duplicate element, you just have to create a set of the name of the type and duplicates will be delete. I have created an Acceleo project to show you how you can do it. My example uses Ecore as a metamodel contrary to UML in your example but it doesn't matter for that problem.

You can see that there are two ways to do it, and it is exactly the same mechanism. With OCL you should use "myCollection->collect(a | a.doSomething())" but we also tolerate "myCollection.doSomething()". both operation will create a collection. Then you just have to use asSet() to suppress all duplicates.

yeah, thats great. Thank you.

I tried this, but no luck...

[template public parametersOperations(class : Classifier)]

[let packDomain:String = packageDomain(class)]
// [protected ('for imports')]
[for (eOperation : Operation | class.getAllOperations())]
[for (name : String | eOperation.ownedParameter -> collect(param | param.type) -> collect (type | type.name) -> asSet())]
import [packDomain + '.' + name/];
[/for]
[/for]
// [/protected]
[/let]

[/template]

Maybe it's because I'm using Class and not EClass? How can I use EClass from a Class (class.oclAsType(EClass) --> error cast)?

Hi Sergio,

With this, you still have duplicate entries? or the processing fails
before that?

I'd suggest you use this:

[template public parametersOperations(class : Classifier)]
// [protected ('for imports')]
[for (typeName : String |
class.getAllOperations().ownedParameter.type.name->asSet())]
import [packageDomain(class) + '.' + typeName/];
[/for]
// [/protected]
[/template]

Thank you!

Yes, the last one was right!

(I left the project in stand by until this month.)
