Class RenderKitFactory
- java.lang.Object

- jakarta.faces.render.RenderKitFactory
-
- All Implemented Interfaces:
FacesWrapper<RenderKitFactory>
public abstract class RenderKitFactory extends Object implements FacesWrapper<RenderKitFactory>
RenderKitFactory is a factory object that registers and returns
RenderKit
instances. Implementations of Jakarta Faces must provide at least a default implementation ofRenderKit
. Advanced implementations (or external third party libraries) may provide additionalRenderKit
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 Jakarta Faces. This instance can be acquired, in a portable manner, by calling:RenderKitFactory factory = (RenderKitFactory) FactoryFinder.getFactory(FactoryFinder.RENDER_KIT_FACTORY);
Usage: extend this class and push the implementation being wrapped to the constructor and use
getWrapped()
to access the instance being wrapped.

@Deprecated public RenderKitFactory()
Deprecated.Use the other constructor taking the implementation being wrapped.
-
RenderKitFactory
public RenderKitFactory(RenderKitFactory wrapped)
If this factory has been decorated, the implementation doing the decorating should push the implementation being wrapped to this constructor. The
getWrapped()
will then return the implementation being wrapped.- Parameters:
wrapped
- The implementation being wrapped.

Method Detail

getWrapped
public RenderKitFactory getWrapped()
If this factory has been decorated, the implementation doing the decorating may override this method to provide access to the implementation being wrapped.
- Specified by:
getWrapped
in interfaceFacesWrapper<RenderKitFactory>
- Returns:
- the wrapped instance.

- 2.0

addRenderKit
public abstract void addRenderKit(String renderKitId, RenderKit renderKit)
Register the specified
RenderKit
instance, associated with the specifiedrenderKitId
, to be supported by thisRenderKitFactory
, replacing any previously registeredRenderKit
for this identifier.- Parameters:
renderKitId
- Identifier of theRenderKit
to registerrenderKit
-RenderKit
instance that we are registering- Throws:
NullPointerException
- ifrenderKitId
orrenderKit
isnull
-
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 specifiedFacesContext
, if non-null
. If there is no registeredRenderKit
for the specified identifier, returnnull
. The set of available render kit identifiers is available via thegetRenderKitIds()
method.- Parameters:
context
- FacesContext for the request currently being processed, ornull
if none is available.renderKitId
- Render kit identifier of the requestedRenderKit
instance- Returns:
- a
RenderKit
instance - Throws:
IllegalArgumentException
- if noRenderKit
instance can be returned for the specified identifierNullPointerException
