Validation (warning) when object is not used [message #1804343] Fri, 22 March 2019 13:35 Go to next message
Eclipse UserFriend
Hi,

I would like to give warning for the variable (object) that was declared but never used in code. Any example for this?

do you want to do this locally or globally.
if locally: simply traverse the file for references
if globally: this will be hard. you have to do this in the index. and do it as expensive validation which is explicitely triggered

Locally will do for now. Your answer in my previous topic helped me to understand how to traverse the file for references.

Thanks!

well i would be doing basically the same.
traverse the tree. looks where references are.
maybe use org.eclipse.xtext.EcoreUtil2.findCrossReferences(EObject, Set<? extends EObject>, ElementReferenceAcceptor)

Yes. I understood that I need to traverse but didn't know how.

Like I said, I am just a beginner :)

the esiest is to traverse your model along the structure

ask model for its models
have a look if there are student, course, enroll.
have a looks at the references within these
