public class FXMLDocumentController implements Initializable {



    @Override

    public void initialize(URL url, ResourceBundle rb) {



        listViewArtigosMercado.setCellFactory((ListView<String> param) -> new ListCell<String>(){

            @Override

            public void updateItem(String name, boolean empty){

                super.updateItem(name,empty);

                if (name.equals("Vender")){

                    setText(name);

                    ((Node)this).setId("id");

                }

            }

        });

    }

}

I want that my this keyword whether reference itself to my new ListCell<String> rather than FXMLDocumentController, once ListCell extends

java.lang.Object,

**javafx.scene.Node**,

javafx.scene.Parent,

javafx.scene.layout.Region,

javafx.scene.control.Control,

javafx.scene.control.Labeled,

javafx.scene.control.Cell<T>,

javafx.scene.control.IndexedCell<T>,

javafx.scene.control.ListCell<T>

and class Node have method setId.

How reference my new class inside of implementation?

Insted of (Node)this use Node.this. You can get the current object of the outer class by calling OuterClass.this.

Then you can just call it's method:

(OuterClass.this).methodOfOuterClass();

Remove the cast and this, it's unambiguous call referring to a parent's method:

setId("id");

Look carefully at how you are using setText(name);. The method is from Labeled, but you neither used this nor cast it to that class, simply because there was no need for that. ListCell is a Labeled as well as a Node.

Here, As I can see you are using lambda function inside the initialize method as below.

listViewArtigosMercado.setCellFactory((ListView<String> param) -> new ListCell<String>(){

      @Override

      public void updateItem(String name, boolean empty){

      super.updateItem(name,empty);

      if (name.equals("Vender")){

          setText(name);

              ((Node)this).setId("id");

          }

      }

 });

Lambda does not treat as the anonymous class. So the scope of the lambda function is limited to that particular enclosing close. this is to reference for that particular scop only. so you can not write this.setId('Id'); inside setCelFactor lambda because it does not contain setId method.

Here lambda is treated as a child class of the parent class. In your case, its child class of FXMLDocumentController so it has an accessibility of all public method of parent class so you can use setID or other methods direct without any reference.
