public abstract class AbstractRenderService<T>
extends org.apache.wicket.markup.html.panel.Panel
implements IObserver, IRenderService

Utility class that bundles a lot of the functionality needed for visual plugins. It registers an IRenderService, with itself as the Component.

The configuration parameters are as follows, with the class of the expected service between brackets:

• wicket.model (IModelReference) The IModel that is available with the getModel() method, is the model that is provided by a IModelReference service. The name for this service can be found in the configuration with the wicket.model key. When the model is changed with setModel(), this change is propagated to the IModelReference service. When another plugin changes the model or the model object changes, the Component#onModelChanged() method is invoked. It is recommended to override this method to respond to changes.
• wicket.id (IRenderService) The primary task of the RenderPlugin is to provide an IRenderService implementation.
• wicket.extensions (IRenderService) A list of service names for child render services. These child services will be added to the plugin directly.
• wicket.behavior A list of service names for IBehaviorServices. The behaviors that are exposed by these services are added to the Component.
• wicket.variant (Layout) The layout variantion to use. In contrast with Wickets default, the variation is not inherited from the parent.
• wicket.skin (CSS stylesheet) An array of stylesheets that will be added to the HTML head.
• wicket.css (CSS) An array of CSS class names that will be added to the Component that is provided by this render service.
• wicket.feedback (Feedback) The feedback service id. When specified, a IFeedbackMessageFilter that accepts messages generated by the component is registered with this id.

The IPluginConfig that was used to create the service.

redraw

protected void redraw()

For more fine-grained redrawing, subclasses should override the render(PluginRequestTarget) method.

addExtensionPoint

protected void addExtensionPoint(String extension)

createExtensionPoint

protected abstract AbstractRenderService.ExtensionPoint createExtensionPoint(String extension)

Create an extension point with the specified name.

removeExtensionPoint

The id that the component is bound to. Undefined when the service has not yet been bound to a parent or has been released.

Specified by:

getId in interface org.apache.wicket.request.component.IRequestableComponent
