[antlr-interest] Grouping the parsed data

[Marcel Cerveny]

Hello there!

After a while of really pleasant work with antlr I bumped into one problem.
I do a parsing of quite general source files, which describe
interfaces. However one of the requirements is to have a freedom of
placing say other used interfaces, meaning one interface source could
look like:
public interface ITest {
  using John, Paul;
  const int aaa = 1;
  int bbb;
  using George, Ringo;
  int ccc();
}

My problem is that I want to have the using node stored as the
firstChild of the curly bracket. Moreover, I want all the uses
specified later have stored as the children of (first) uses node.

Now, I can create an mandatory (actual or { ## = #[EMPTY]; }) using
node, but how can I move parsed information into other node during the
process of parsing. Of course I can to rearrange the AST after being
created, but I'd like to make this during parsing, if it is possible.

Thanx in advance for any of your hints.
Marcel
