How to modify ContainerBasedScope in a SimpleScope way? [message #522320]

Hello,

my primary subject is to get case insensitivity working on crossreferences.
So I bound my own linkingservice with these changes:

eObjectDescription = getContentByNameIgnoreCase(scope,s);
...
while (contents.hasNext()) {
IEObjectDescription element = contents.next();

if (name.equalsIgnoreCase(element.getName()))
return element;
}
...

But when reaching the ContainerBasedScope, i can't find the corresponding point where the names will be compared.

Does this indexing thing allow me to get this working in some way?

regards
Tim S.

Hi Tim,

wouldn't it be easier to configure an IQualifiedNameProvider that
produces only lowercase or uppercase names? Otherwise it'ld be hardly
possible to implement the query by name without iterating each and every
container.

I'ld decorate the IScope in your ScopeProvider and do something similar
to this pseudo code:

MyDslScopeProvider extends .. {

public IScope getScope(EObject, EReference) {
final IScope result = super.getScope(..);
return new IScope() {
IEObjectDescription getContentByName(String name) {
return result.getContentByName(name.toLowerCase());
}
IEObjectDescription getContentByEObject(EObject obj) {
IEObjectDescription = result.getContentByEObject(..);
// use the original name of the obj instead of the
// lowercase one
return new AliasedEObjectDescription(..);
}
// the other calls should return descriptions which expose
// their real name instead of the lowercase / uppercase version
...
}
}

}

Hope that helps.

Regards,
Sebastian

Thank you a lot,
I took your advice and resolved it with my QualifiedNameProvider. Smile
