A Utility Method for Edit Commits in a JavaFX TableView

I found it difficult to string together a long statement involving casting to retrieve a TableRow's backing object in a JavaFX TableView, so I wrote this method.

static <T, S> T getObjectAtEvent(CellEditEvent<T, S> evt) {
  
 TableView<T> tableView = evt.getTableView();
  
 ObservableList<T> items = tableView.getItems();
  
 TablePosition<T,S> tablePosition = evt.getTablePosition();

 int rowId = tablePosition.getRow();
 
 T obj = items.get(rowId);

 return obj;
}

This method is for working with JavaFX Controller objects like these

@FXML
TableColumn<MyObject,Number> tcId;
 
@FXML
TableColumn<MyObject,String> tcData;

@FXML
TableView<MyObject> tblObjects;

Where MyObject is a POJO with id and data fields.

The getObjectAtEvent() method can be used in the Edit Commit handler for the TableColumn.

tcData.setCellValueFactory(new PropertyValueFactory<MyObject,String>("data"));  
tcData.setCellFactory(TextFieldTableCell.forTableColumn());    
tcData.setOnEditCommit((evt) -> {

 MyObject obj = getObjectAtEvent(evt);  // <--- APPLYING THE METHOD

 if( !dirtyFlag.get() ) {
  dirtyFlag.set(true);
 }
 String oldData = obj.getData();
 obj.setData( evt.getNewValue() );
 updateList.add( new UpdateObject(obj.getId(), obj.getData(), oldData));
});
