javax.faces.render Class RenderKitFactory

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

public abstract class RenderKitFactory
extends 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);

字段摘要
`static String`	`HTML_BASIC_RENDER_KIT` The render kit identifier of the default `RenderKit` instance for this JavaServer Faces implementation.

构造器摘要
`RenderKitFactory()`

方法摘要
`abstract void`	`addRenderKit(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, 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 Iterator<String>`	`getRenderKitIds()` Return an `Iterator` over the set of render kit identifiers registered with this factory.

方法详细信息

addRenderKit

public abstract void addRenderKit(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.

参数:: renderKitId - Identifier of the RenderKit to register; renderKit - RenderKit instance that we are registering
抛出异常:: NullPointerException - if renderKitId or renderKit is null

getRenderKit

public abstract RenderKit getRenderKit(FacesContext context,
                                       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.

参数:: context - FacesContext for the request currently being processed, or null if none is available.; renderKitId - Render kit identifier of the requested RenderKit instance
抛出异常:: IllegalArgumentException - if no RenderKit instance can be returned for the specified identifier; NullPointerException - if renderKitId is null

getRenderKitIds

public abstract Iterator<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.
