  - ### visit

    public void visit(GroovyCodeVisitor visitor)
    Description copied from class: `ASTNode`
    Accepts a code visitor for AST traversal and transformation. Subclasses must implement this method to support visitor pattern-based processing. The visitor pattern enables decoupling of AST structure from processing logic.
    Overrides:
      `visit` in class `MethodPointerExpression`
    Parameters:
      `visitor` - the `GroovyCodeVisitor` to process this node

  - ### transformExpression

    public Expression transformExpression(ExpressionTransformer transformer)
    Description copied from class: `Expression`
    Transforms this expression and any nested expressions according to the provided transformer. This method is called during AST transformation phases and must recursively transform any nested expressions to support full AST tree transformation.
    Overrides:
      `transformExpression` in class `MethodPointerExpression`
    Parameters:
      `transformer` - the `ExpressionTransformer` to apply
    Returns:
      a transformed copy of this expression (or this expression itself if no changes are needed)

  - ### getText

    public String getText()
    Description copied from class: `ASTNode`
    Returns a human-readable text representation of this AST node. Used for debugging and error messages. Default implementation returns a message indicating the representation is not yet implemented for this node type.
    Overrides:
      `getText` in class `MethodPointerExpression`
    Returns:
      text representation of this node, or placeholder for unimplemented types
