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.

  • Method Details

    • onInitialize

      protected void onInitialize()
      Description copied from class: Component
      This method is meant to be used as an alternative to initialize components. Usually the component's constructor is used for this task, but sometimes a component cannot be initialized in isolation, it may need to access its parent component or its markup in order to fully initialize. This method is invoked once per component's lifecycle when a path exists from this component to the Page thus providing the component with an atomic callback when the component's environment is built out.

      Overrides must call super#Component.onInitialize(). Usually this should be the first thing an override does, much like a constructor.

      Parent containers are guaranteed to be initialized before their children

      It is safe to use Component.getPage() in this method

      NOTE:The timing of this call is not precise, the contract is that it is called sometime before Component.onBeforeRender().

      Overrides:
      onInitialize in class MarkupContainer

    • newAjaxPagingNavigationBehavior

      protected AjaxPagingNavigationBehavior newAjaxPagingNavigationBehavior(IPageable pageable, String event)
      Parameters:

      event - the name of the default event on which this link will listen to
      Returns:
      the ajax behavior which will be executed when the user clicks the link

      public void onClick(AjaxRequestTarget target)
      Performs the actual action of this component, performing a non-ajax fallback when there was no AjaxRequestTarget available.
      Specified by:
