/**
* DataView is a basic implementation of AbstractDataView.
*
* Data views aim to make it very simple to populate your repeating view from a
* database by utilizing {@link IDataProvider} to act as an interface between
* the database and the dataview.
*
*
*
*
* Example:
*
*
* <tbody>
* <tr wicket:id="rows">
* <td><span wicket:id="id">Test ID</span></td>
* ...
*
*
*
* Though this example is about a HTML table, DataView is not at all limited to
* HTML tables. Any kind of list can be rendered using DataView.
*
* And the related Java code:
*
*
* add(new DataView("rows", dataProvider)
* {
* public void populateItem(final Item item)
* {
* final UserDetails user = (UserDetails)item.getModelObject();
* item.add(new Label("id", user.getId()));
* }
* });
*
*
* @see IDataProvider
* @see IPageable
