TransformingCodeVisitor (Groovy 6.0.0-alpha-1)

org.codehaus.groovy.ast.TransformingCodeVisitor

```
public class TransformingCodeVisitor
extends CodeVisitorSupport
```
Code visitor that combines depth-first traversal with expression transformation, delegating both to an underlying ClassCodeExpressionTransformer.
This visitor implements a two-phase approach for each statement and expression:
1. Depth-first traversal via the parent CodeVisitorSupport class visits child nodes
2. Expression transformation via the ClassCodeExpressionTransformer processes the node
This pattern enables both traversal and transformation in a single pass. The transformer receives fully-traversed nodes, allowing it to operate on complete subtrees or apply post-processing transformations after children are visited.
Typical usage involves creating a subclass of ClassCodeExpressionTransformer and passing it to this visitor:
```
   ClassCodeExpressionTransformer transformer = new MyTransformer(...);
   TransformingCodeVisitor visitor = new TransformingCodeVisitor(transformer);
   node.visit(visitor);
 
```
