extends OrmDataProvider<U>

This class called OrmDataProvider is an ORM based Wicket DataProvider. For a customization you can use a your own IColumn implementations or you can overwrite selected methods of this provider.

The implementation generates two database requests per a one rendering, the first one get size and the second one get paged data. You can overwrite the two data methods: iterator() and the size() for more optimization.

The current class uses a WicketApplication implementation, which must implement the interface OrmHandlerProvider for an ORM support. See the example:

See the simple sample:

 Criterion<Hotel> allActiveHotels = Hotel.ACTIVE.whereEq(true);
  UjoDataProvider<Hotel> dataProvider = UjoDataProvider.of(allActiveHotels);

  dataProvider.addColumn(Hotel.NAME);
  dataProvider.addColumn(Hotel.CITY.add(City.NAME)); // An example of relations
  dataProvider.addColumn(Hotel.STREET);
  dataProvider.addColumn(Hotel.PRICE);
  dataProvider.addColumn(KeyColumn.of(Hotel.CURRENCY, SORTING_OFF));
  dataProvider.addColumn(Hotel.STARS);
  dataProvider.addColumn(Hotel.PHONE);
  dataProvider.setSort(Hotel.NAME);

  panel.add(dataProvider.createDataTable("datatable", 10));
