Examples of org.antlr.runtime.tree.TreeWizard.visit()

org.antlr.runtime.tree.TreeWizard.visit()
Visit every ttype node in t, invoking the visitor. This is a quicker version of the general visit(t, pattern) method. The labels arg of the visitor action method is never set (it's null) since using a token type rather than a pattern doesn't let us set a label.

                        tokens.delete(a.token.getTokenIndex());     // kill "id="
                        tokens.delete(child.token.getTokenIndex());
                    }
                }
            });
        wiz.visit(t, ANTLRv3Parser.LIST_LABEL_ASSIGN, // ^('+=' id ^(RULE_REF [arg])), ...
            new TreeWizard.Visitor() {
      @Override
              public void visit(Object t) {
                  CommonTree a = (CommonTree)t;
                  CommonTree child = (CommonTree)a.getChild(0);
