    - #### ClosureExpression

          public ClosureExpression​(Parameter[] parameters,
                                   Statement code)

  - ### Method Detail

    - #### 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 String toString()

      Overrides:
        `toString` in class `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 String getText()

      Overrides:
        `getText` in class `ASTNode`
