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.

      @Override
               public void visit(Object t) {
                   tokens.delete(((CommonTree)t).token.getTokenIndex());
               }
           });
        wiz.visit(t, ANTLRv3Parser.BANG,
           new TreeWizard.Visitor() {
      @Override
               public void visit(Object t) {
                   tokens.delete(((CommonTree)t).token.getTokenIndex());
               }
