 package javax.faces.render;
 

The presence of this annotation on a class automatically registers the class with the runtime as a Renderer. The value of the renderKitId() attribute is taken to be the render-kit-id to which an instance of this Renderer is to be added. There must be a public zero-argument constructor on any class where this annotation appears. The implementation must indicate a fatal error if such a constructor does not exist and the application must not be placed in service. Within that RenderKit, The value of the rendererType() attribute is taken to be the renderer-type, and the value of the componentFamily() attribute is to be taken as the component-family. The implementation must guarantee that for each class annotated with FacesRenderer, found with the algorithm in section JSF.11.5, the following actions are taken.

  • Obtain a reference to the RenderKitFactory for this application.

  • See if a RenderKit exists for render-kit-id. If so, let that instance be renderKit for discussion. If not, the implementation must indicate a fatal error if such a RenderKit does not exist and the application must not be placed in service.

  • Create an instance of this class using the public zero-argument constructor.

  • Call RenderKit.addRenderer(java.lang.String,java.lang.String,javax.faces.render.Renderer) on renderKit, passing component-family as the first argument, renderer-type as the second, and the newly instantiated RenderKit instance as the third argument.

 
 public @interface FacesRenderer {


    

The value of this annotation attribute is taken to be the render-kit-id in which an instance of this class of Renderer must be installed.

 

The value of this annotation attribute is taken to be the renderer-type which, in combination with componentFamily can be used to obtain a reference to an instance of this Renderer by calling javax.faces.render.RenderKit.getRenderer(java.lang.String, java.lang.String).

 
    String rendererType();


    

The value of this annotation attribute is taken to be the component-family which, in combination with rendererType can be used to obtain a reference to an instance of this Renderer by calling javax.faces.render.RenderKit.getRenderer(java.lang.String, java.lang.String).
