SimpleNode class missing childrenAccept method

[Christoph Leuzinger-3]

Hello,

I'm building a parser using JJTree and following Tom Copeland's book in
the process. The book shows an example visitor adapter class where all
visit() methods are calling a method called childrenAccept() on the
SimpleNode passed to the visit() method, e. g.:

public Object visit(SimpleNode node, Object data) {
  return node.childrenAccept(this, data);
}

However, there is no such method in the SimpleNode class generated by
JJTree. Is this a custom method or do I have to set an option for it to
be generated?

I'm using the Eclipse JavaCC plugin v1.5.10 which in turn contains
JavaCC v4.0.

Thanks in advance,
  Christoph

Well, nevermind. I just got past this problem by deleting the Node
interface and the SimpleNode class. The newly generated files now
contain the missing method.

Seems like I have been using stale files from a JJTree run that had
the VISITOR option disabled.

Sorry about the noise,
  Christoph
