Hello,
I have a class Sca,with one attribute List<String> xxx,I want print all
the elements in this list,I write the following statment in MOFScript.
In the context of Sca,
self.xxx->forEach(s:string)
print(s+",")
when I execute the code (of course ,this is not an empty list),none of the
elements is printed.Does anyone knows what the problem is?

Thanks a lot!

Hello,
I don't think this is related to the question about self. doesn't work.
I suppose maybe the syntax is wrong somewhere,but couldn't find any
clue.Do you have any idea?

Many thanks!

Hello,

Well, I am not sure what your (s:string) is. Is "s" a reference to some meta
thing in your metamodel? In that case you have forgotten the
inModel.string.. Like if you e.g. want to filter a collection to only return
a uml class you would have to write self.ownedElement->forEach(c: uml.Class)
where uml is the name of your input model parameter.

Hello,
Well, the problem is still not solved.As I described in my first post,s
means a variable of type String.I think this iteration for string is
right,what do you think?
-------------------------------
I have a class Sca,with one attribute List<String> xxx,I want print all
the elements in this list,I write the following statment in MOFScript:
In the context of Sca,
self.xxx->forEach(s:string)
print(s+",")
--------------------------------

Thanks

Hello,

Running:
myMdl.Test::main(){

self.stringList->forEach(s){

stdout.println("A " + s)

}

}

on a model A (test- stringList[eeeeeeee, ttttttttttt]) conforming to
metamodel X containing 1 EClass that has 1 EAttribute of type EString upper
bound -1.

Gives the following result:

## Loading source model - My.test...(Loading time 16 - Msec)

## Executing MOFScript Specification

## Starting transformation: "ExampleTransformation"

A eeeee

A tttttttttttt

I can still not understand what this (s:string) of yours is...

Cheers,
G

Hello,
finally,the problem is solved by adding '{}' around the statment of
iteration.
I'm happy!

Thank you very much!
