TreeTableView how to create a specific cell based on the item

I have to create my own implementation of CellFactory for TreeTableView. My cell can contain two types of values - String and Enums. Based on this type I want to have another implementation of displaying this item.

The easy way is verifying the type in Cell#updateItem and split in this method.

But how to separate this on the CellFactory level? Pseudocode to better describe.

public class EditableDataObjectValueCellFactory implements Callback<TreeTableColumn<ITableEntry, ?>,
    TreeTableCell<ITableEntry, ?>> {

  @Override
  public TreeTableCell<ITableEntry, ?> call( TreeTableColumn<ITableEntry, ?> aColumn ) {
     if(aColumn.getRenderedRow().getValue() instanceOf Enum) 
        return new EnumTreeCell();
     return new BasicTreeCell();
  }
}
