Hi,
in my DSL, I want to allow to qualify elements in separate places using a
qualified path notation like in Java. My metamodel looks like this:
abstract class Element {
}
class PackageElement extends Element {
reference children[*] container : Element;
}

sorry for sending the post too early.
in my DSL, I want to allow to qualify elements in separate places using a
qualified path notation like in Java. My metamodel looks like this:
abstract class Element {
String name;
}
class PackageElement extends Element {
reference children[*] container : Element;
}
class ClassElement extends Element {
}
Now in my syntax, I want to use qualified names like in
"com.foo.bar.Test"
where all of com, foo, bar refer to PackageElement model elements.
Since this notation is left-recursive, I guess I cannot use mere
Classtemplates. But if I use an OperatorTemplate, I would still have to
use parentheses, right?
So is there any other solution in TCS, or would I rather have to create a
transitionary MetaModel and a Model transformation maybe to get this
language to work?
regards,
Thibault

Hi Thibault,
TCS does not currently provide automatic support for such qualified
names. This will very likely be supported in future versions.
In the mean time, you can use a pivot metamodel as you proposed.

Frédéric
