Hi. I'm developing a language that supports references to UML elements, i found this example https://christiandietrich.wordpress.com/2011/07/17/xtext-2-0-and-uml/ in christian Blog and it's work fine, But i want that when i generate my DSL grammar then referencing to UML elements by tap CTRL+ SPACE i want just the name like the example in christian Blog : <Package> Test and Class A ==> test.A
But I want just the name of Class A like this : <Package> Test and Class A ==> A
is there any solution about it thinks .

Can you be more precise

You want to simply have two references?

But what if there are 2 As?

besides this: implements UmlQualifiedNameProvider

e.g. (untested)

public QualifiedName qualifiedName(org.eclipse....uml.Class clazz) {
return QualifiedName.create(clazz.getName()); // or simple name or .....
}

thats not possible

either

public QualifiedName qualifiedName(org.eclipse.uml2.uml.Class clazz ) {
...
}

or

public QualifiedName qualifiedName(org.eclipse.uml2.uml.Activity activite ) {
....
}

you have to navigate /traverse from class to activity or vice versa or create multiple methods
(i dont know how the model/names you want to build and work on look exactly like)

and if you want to use a multi segement name

return QualifiedName.create(clazz.getName(), activite.getName());

Xtext uses a reflective mechanism (AKA PolymorphicDispatcher) to call the overridden qualifiedName method based on the actual type of the parameter.
This is why, as Christian said, you have to implement a qualifiedName(X element) method for each element type X for which you want a custom calculation of the fully qualified name.

Did you debug the code? It is called? Did you have a look at the Xtext index using the openmodelement dialog? How does the reference look like? How does the name look like?

- the open model element dialog is crtl/cmd + shift + f3 or in the navigate menu
- you debug by setting a breakpoint and start the runtime eclipse via the debug menu
- or add a sysout to e see if it is called.

how does the xml of the uml file look like you test with?

Please give me the damn information I damn asked you for.

Does the pin have a name?
Are the pins inside the open model element dialog
How does the name look like? Is it "hugo" or "bla blubb" or "12345"
How does the reference to the pin in the grammar look like?
