  - ### transform

    public Expression transform(Expression expr)
    NOTE: This method does not visit Expressions within Closures, for performance and historical reasons. If you want those Expressions to be visited, you can do this:

         public class YourTransformer extends ClassCodeExpressionTransformer {
           ...

           @Override
           public Expression transform(final Expression expr) {
             if (expr instanceof ClosureExpression) {
               expr.visit(this);

               return expr;
             }
             // ...
           }
