an extension of antlr.CommonAST that includes extra information about the AST's location. This information is the file and line number where the AST was created. To use this AST node in your tree structure, assuming your antlr.TreeParser is called parser, use parser.setASTNOdeCLass(SymTabAST.class.getName()); make sure you also call setTokenObjectClass for the lexer as well @see SymTabToken

            final DetailAST nameAST = (DetailAST) it.next();
            // find methods using the field
            final Iterator refIt = getReferences(nameAST);
            while (refIt.hasNext()) {
                final Reference ref = (Reference) refIt.next();
                final SymTabAST refNode = ref.getTreeNode();
                final DetailAST refDetail = refNode.getDetailNode();
                // don't need to check a self-reference
                if (refDetail == nameAST) {
                    continue;
                }
                DetailAST parent = refDetail.getParent();
