  - ### visit

    public void visit(ASTNode[] nodes, SourceUnit source)
    Description copied from interface: `ASTTransformation`
    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.
    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.
      `source` - 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.

  - ### sealedNative

    @Incubating public static boolean sealedNative(AnnotatedNode node)
    Reports true if native sealed class information should be written into the bytecode. Will only ever return true after the SealedASTTransformation visit method has completed.
    Returns:
      true for a native sealed class

  - ### sealedSkipAnnotation

    @Incubating public static boolean sealedSkipAnnotation(AnnotatedNode node)
    Reports true if the `Sealed` annotation should not be included in the bytecode for a sealed or emulated-sealed class. Will only ever return true after the `SealedASTTransformation` transform has been invoked.
    Returns:
      true if a `Sealed` annotation is not required for this node
