javax.faces.render
Class RenderKitFactory

java.lang.Object
  extended by javax.faces.render.RenderKitFactory

public abstract class RenderKitFactory
extends java.lang.Object

RenderKitFactory is a factory object that registers and returns RenderKit instances. Implementations of JavaServer Faces must provide at least a default implementation of RenderKit. Advanced implementations (or external third party libraries) may provide additional RenderKit implementations (keyed by render kit identifiers) for performing different types of rendering for the same components.

There must be one RenderKitFactory instance per web application that is utilizing JavaServer Faces. This instance can be acquired, in a portable manner, by calling:

   RenderKitFactory factory = (RenderKitFactory)
    FactoryFinder.getFactory(FactoryFinder.RENDER_KIT_FACTORY);
 


Field Summary
static java.lang.String HTML_BASIC_RENDER_KIT
          The render kit identifier of the default RenderKit instance for this JavaServer Faces implementation.
 
Constructor Summary
RenderKitFactory()
           
 
Method Summary
abstract  void addRenderKit(java.lang.String renderKitId, RenderKit renderKit)
          Register the specified RenderKit instance, associated with the specified renderKitId, to be supported by this RenderKitFactory, replacing any previously registered RenderKit for this identifier.
abstract  RenderKit getRenderKit(FacesContext context, java.lang.String renderKitId)
          Return a RenderKit instance for the specified render kit identifier, possibly customized based on dynamic characteristics of the specified FacesContext, if non-null.
abstract  java.util.Iterator<java.lang.String> getRenderKitIds()
          Return an Iterator over the set of render kit identifiers registered with this factory.

Method Detail

addRenderKit

public abstract void addRenderKit(java.lang.String renderKitId,
                                  RenderKit renderKit)

Register the specified RenderKit instance, associated with the specified renderKitId, to be supported by this RenderKitFactory, replacing any previously registered RenderKit for this identifier.

Parameters:
renderKitId - Identifier of the RenderKit to register
renderKit - RenderKit instance that we are registering
Throws:
java.lang.NullPointerException - if renderKitId or renderKit is null

getRenderKit

public abstract RenderKit getRenderKit(FacesContext context,
                                       java.lang.String renderKitId)

Return a RenderKit instance for the specified render kit identifier, possibly customized based on dynamic characteristics of the specified FacesContext, if non-null. If there is no registered RenderKit for the specified identifier, return null. The set of available render kit identifiers is available via the getRenderKitIds() method.

Parameters:
context - FacesContext for the request currently being processed, or null if none is available.
renderKitId - Render kit identifier of the requested RenderKit instance
Throws:
java.lang.IllegalArgumentException - if no RenderKit instance can be returned for the specified identifier
java.lang.NullPointerException - if renderKitId is null

getRenderKitIds

public abstract java.util.Iterator<java.lang.String> getRenderKitIds()

Return an Iterator over the set of render kit identifiers registered with this factory. This set must include the value specified by RenderKitFactory.HTML_BASIC_RENDER_KIT.
