[MTL] Reading Opaque Expressions [message #638226]

Hi MTL folks,

if I read the body of an OpaqueExpression with MTL, I get something like "[<body>]". There are that brackets what is bothering me.

Is this specified this way? Is the value of an opaque body "[something]" even if I define it "something"?
How do I get rid of them?

Thanks for help,
Siegfried

Hi Siegfried,

What are you doing exactly? What do you mean by "I get something like [<...>]"?

I'd say these brackets come from the fact you are manipulating a list, but Acceleo doesn't generate them. Thus I don't know where you "get" them.

Hi Laurent,

of course you are right. I'm dealing with lists.
I'm doing some tests with the UML action model.
[if (oa.oclIsTypeOf(OpaqueAction))][oa.name/] [oa.body/][/if]
That delivers "'somename' ['content of body']"
The following statement does better:
[oa.body->first()/]
That delivers "'somename' 'content of body'"

Thanks,
Siegfried

Siegfried,

Okay, then I was wrong with my assumption that "Acceleo doesn't generate them" ... I believe you are using an older version of Acceleo (IIRC, I've specialized the generation of "List" as Strings since 3.0.0).

You should no longer see those brackets with an updated Acceleo. If you do ... then something escapes me and... please raise a bug if it's the case Smile

I had been thinking that Acceleo does not transform Activity Diagrams to Code. can you please showme how do you do?

Hello,

Please create your own thread for question instead of necro-ing unrelated old threads. As for your question, you can use whatever input for Acceleo generation as long as they're EMF models, such as activity diagrams that can be read as an UML diagram and passed on to an acceleo generator.
