Method Details

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;
     }
     // ...
   }
 }
