A convenience implementation of the Callback interface, designed specifically
for use within the
TableColumn
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 a ReadOnlyObjectWrapper.
