All Implemented Interfaces:

Serializable, IAjaxLink, IClusterable, IConverterLocator, IRequestListener, ILinkListener

public class AjaxPagingNavigationIncrementLink
extends PagingNavigationIncrementLink<Void>
implements IAjaxLink

An incremental Ajaxian link to a page of a PageableListView. Assuming your list view navigation looks like

 
                 [first / << / <] 1 | 2 | 3 [> / >> /last]
 
 

and "<" meaning the previous and "<<" goto the "current page - 5", than it is this kind of incremental page links which can easily be created. This link will update the pageable and itself or the navigator the link is part of using Ajax techniques, or perform a full refresh when ajax is not available.
