EuGENia link attributes [message #21991]

Hi there,

I'm using EuGENia to help with a diagram editor of mine, which creates
components including GMF links. I can specify labels for these links using
gmf annotations such as, @gmf.link(... label="name"). I'm now wondering
whether there is an easy way to go abouts adding labels to the ends of the
link (e.g., as you might have when defining association multiplicities in
a standard UML editor)?

All the best,

Edd

Hi Edd,

This is not supported by EuGENia at the moment but I'll have a look to
see how it could be. Does your metamodel like this?

class Class {

}

class AssociationEnd {
attr String name;
ref Class type;
}

class Association {
val AssociationEnd[2] ends;
}

or like this?

class Class {

}

class Association {
val Class[2] ends;
}

Cheers,
Dimitris

It is more like the latter, but with 'ref's instead of 'val's -- so more
than one association can comprise the same class:

class Association {
...
ref Class xEnd;
ref Class yEnd;
}

Hi Edd,

I've put together an example that does this and it's now available under

http://www.eclipse.org/gmt/epsilon/examples/index.php?exampl e=org.eclipse.epsilon.eugenia.examples.endlabels

I've had to use the "polishing" feature of EuGENia

http://epsilonblog.wordpress.com/2009/06/15/eugenia-polishin g-your-gmf-editor/

as multiple connection labels are not currently supported by the
annotations. If you have any trouble adapting the EOL code to your
example please let me know.

Cheers,
Dimitris

Ahh, brilliant :) Thanks Dimitris -- just what was needed. And I'm sure
this will be handy to know in the long run for everyone!

Ta,

Edd
