- ## Method Details

  - ### getExpression

    public Expression getExpression()

  - ### 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 `ASTNode`
    Returns:
      text representation of this node, or placeholder for unimplemented types

  - ### getType

    public ClassNode getType()
    Description copied from class: `Expression`
    Returns the type of this expression. If the type has not been explicitly set, this method returns a dynamic type to support dynamic typing.
    Overrides:
      `getType` in class `Expression`
    Returns:
      the `ClassNode` representing this expression's type

  - ### isDynamic

    @Deprecated public boolean isDynamic()
    Deprecated.

  - ### 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.
    Specified by:
      `transformExpression` in class `Expression`
    Parameters:
      `transformer` - the `ExpressionTransformer` to apply
    Returns:
      a transformed copy of this expression (or this expression itself if no changes are needed)

  - ### 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 `ASTNode`
    Parameters:
      `visitor` - the `GroovyCodeVisitor` to process this node
