- ## Method Details

  - ### visit

    public void visit​(GroovyCodeVisitor visitor)
    Overrides:
      `visit` in class `ASTNode`

  - ### transformExpression

    public Expression transformExpression​(ExpressionTransformer transformer)
    Description copied from class: `Expression`
    Return a copy of the expression calling the transformer on any nested expressions
    Specified by:
      `transformExpression` in class `Expression`

  - ### toString

    public java.lang.String toString()
    Overrides:
      `toString` in class `java.lang.Object`

  - ### getCode

    public Statement getCode()
    This gets the code statement of the closure. You can read this method to find out what actions the closure is going to perform.
    Returns:
      the code statement of the closure

  - ### setCode

    public void setCode​(Statement code)
    This sets the code statement of the closure. You can use this method in order to add more actions during the closure execution.
    Parameters:
      `code` - the new Statement

  - ### getParameters

    public Parameter[] getParameters()
    Returns:
      an array of zero (for implicit it) or more (when explicit args given) parameters or null otherwise (representing explicit no args)

  - ### isParameterSpecified

    public boolean isParameterSpecified()
    Returns:
      `true` if one or more explicit parameters are supplied

  - ### getVariableScope

    public VariableScope getVariableScope()

  - ### setVariableScope

    public void setVariableScope​(VariableScope variableScope)

  - ### getText

    public java.lang.String getText()
    Overrides:
      `getText` in class `ASTNode`
