Hi everybody,
I hope this question was not asked before... at least I could not find
it in the archives...
I am using the java15.g from Michael Studman and I found that nodes like
EXTENDS_CLAUSE and IMPLEMENTS_CLAUSE are inserted even though they are
empty and do not contain any additional information. Can anyone help me
to get rid of them? Meaning: how do I have to change the grammar so that
they are not inserted in the AST when they are empty?
My example is a stupid
public class Test1
{
}
Thanks in advance!
Dieter
