Artifact fileName [message #1767125]

All,

I am processing a UML deployment diagram where one of the nodes contains and artifact. The artifact has a value set as its fileName.

How may I access the fileName? I doesn't show up in the content assist.

Here's my template:

[template public generate(n : Node)]
[file ('deploy.sh', false)]
    [for (ne : NamedElement | ownedMember)]
       [ne.toString()/] 
    [/for]
[/file]
[/template]

Here's the output:

org.eclipse.uml2.uml.internal.impl.ArtifactImpl@c7a977f (name: TripleReceive, visibility: public) (isLeaf: false, isAbstract: false, isFinalSpecialization: false) (fileName: gov.nist.hla:gov.nist.hla.Triple.TripleReceive:0.0.1)

1) You have the same file name in file tag with false as the second parameter - the same file will be generated for each node overwriting the previous one.

2) fileName attribute belongs to the Artifact not to any NamedElement. If you want to iterate over the artefacts only you could do something like it:

[template public generate(n : Node)]
[file (n.name.concat('deploy.sh'), false)]
    [for (ne : Artifact | n.ownedMember->filter(Artifact))]
       [ne.fileName/] 
    [/for]
[/file]
[/template]

Thanks Tomasz,

I have been looking for a comprehensive set of documentation for this template language. What I have so far is sketchy and down right terse. Does any such documentation exist?

Thanks again

Hi

You've already asked about documentation and been answered. Acceleo is far from lacking in documentation. You are welcome to improve it.

In particular:

The file block contains three parameters:

An expression returning a string for the name of the file
A boolean indicating if existing files should be overwritten or if the newly generated content should be appended at the end of the existing file
The encoding of the file

seems to address your problems with file rather well.

M2T languages are particularly easy to debug. I suggest you learn to add debug comments to your output so that you can debug the difference between your expectation and actuality.

Regards

Ed Willink
