```
public abstract class ContextualClassCodeVisitor
extends ClassCodeVisitorSupport
```
A class code visitor which is capable of remembering the context of the current visit. This makes it easier for subclasses to perform context-dependent transformations, where for example it is necessary to check the parent nodes of an AST node before performing some operations.

Since:

2.5.0
