public class LambdaExpression extends ClosureExpression
Represents a lambda expression such as one of these:

     e -> e * 2
     (x, y) -> x + y
     (x, y) -> { x + y }
     (int x, int y) -> { x + y }

- ## Method Details

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

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

  - ### isSerializable

    public boolean isSerializable()

  - ### setSerializable

    public void setSerializable(boolean serializable)
