- java.lang.Object

- javafx.scene.control.cell.MapValueFactory<T>
-
- Type Parameters:
T
- The type of the class contained within the TableColumn cells.
- All Implemented Interfaces:
Callback<TableColumn.CellDataFeatures<Map,T>,ObservableValue<T>>
public class MapValueFactory<T> extends Object implements Callback<TableColumn.CellDataFeatures<Map,T>,ObservableValue<T>>
A convenience implementation of the Callback interface, designed specifically for use within theTableColumn
cell value factory
. An example of how to use this class is:ObservableList<Map> personsMapList = ... TableColumn<Map, String> firstNameColumn = new TableColumn<Map, String>("First Name"); firstNameColumn.setCellValueFactory(new MapValueFactory<String>("firstName")); TableView<Map> table = new TableView<Map>(personMapList); tableView.getColumns().setAll(firstNameColumn);
In this example, there is a list of Map instances, where each Map instance representsa single row in the TableView. The "firstName" string is used as a key into this map, and the value corresponding to this key is returned, if one exists. If the value is an
ObservableValue
, then this is returned directly, otherwise the value is wrapped in aReadOnlyObjectWrapper
