    • 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

    • newAjaxEventBehavior

      protected AjaxEventBehavior newAjaxEventBehavior(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

    • updateAjaxAttributes

      protected void updateAjaxAttributes(AjaxRequestAttributes attributes)

    • onComponentTag

      protected void onComponentTag(ComponentTag tag)
      Description copied from class: Component
      Processes the component tag. Overrides of this method most likely should call the super implementation.
      Overrides:
      onComponentTag in class Component
      Parameters:
      tag - Tag to modify

    • onClick

      public abstract void onClick(AjaxRequestTarget target)
      Listener method invoked on the ajax request generated when the user clicks the link
      Specified by:
      onClick in interface IAjaxLink
      Parameters:
      target -

    • getStatelessHint

      protected boolean getStatelessHint()
      Description copied from class: Component
      Returns whether the component can be stateless. Also the component behaviors must be stateless, otherwise the component will be treat as stateful. In order for page to be stateless (and not to be stored in session), all components (and component behaviors) must be stateless.
      Overrides:
      getStatelessHint in class Component
      Returns:
      whether the component can be stateless
