visit
public void visit(ASTNode[] nodes,
                  SourceUnit sourceUnit)
The method is invoked when an AST Transformation is active. For local transformations, it is invoked once
 each time the local annotation is encountered. For global transformations, it is invoked once for every source
 unit, which is typically a source file.
- Specified by:
- visitin interface- ASTTransformation
- Parameters:
- nodes- The ASTnodes when the call was triggered. Element 0 is the AnnotationNode that triggered this
      annotation to be activated. Element 1 is the AnnotatedNode decorated, such as a MethodNode or ClassNode. For
      global transformations it is usually safe to ignore this parameter.
- sourceUnit- The source unit being compiled. The source unit may contain several classes. For global transformations,
      information about the AST can be retrieved from this object.
