Property:
	name=ValidID ':' type=JvmTypeReference ('NotNull')? (columnName=ValidID)?
;


Getting name and columnName is trivial. But how do I check if Property contains a NotNull token. I tried to access the eContents and eContainer.eContents. But I can only find name and columnName there:

val p = f as Property

for (c : p.eContainer.eContents) {
println(c)
}


Regards
Roger

You have to change the grammar

(notNull?='NotNull')?
