java.lang.Objectjavax.faces.context.FacesContextFactory
public abstract class FacesContextFactory
FacesContextFactory
is a factory object that creates
(if needed) and returns new FacesContext instances, initialized
for the processing of the specified request and response objects.
Implementations may take advantage of the calls to the
release() method of the allocated FacesContext
instances to pool and recycle them, rather than creating a new instance
every time.
There must be one FacesContextFactory instance per web
application that is utilizing JavaServer Faces. This instance can be
acquired, in a portable manner, by calling:
FacesContextFactory factory = (FacesContextFactory)
FactoryFinder.getFactory(FactoryFinder.FACES_CONTEXT_FACTORY);

utilizing the specified Lifecycle instance, for this web

If this factory has been decorated, the implementation doing the decorating may override this method to provide access to the implementation being wrapped. |

public FacesContextFactory getWrapped()
If this factory has been decorated, the
implementation doing the decorating may override this method to provide
access to the implementation being wrapped. A default implementation
is provided that returns null.
getWrapped in interface FacesWrapper<FacesContextFactory>
public abstract FacesContext getFacesContext(java.lang.Object context,
java.lang.Object request,
java.lang.Object response,
Lifecycle lifecycle)
throws FacesException
Create (if needed)
and return a FacesContext instance that is initialized
for the processing of the specified request and response objects,
utilizing the specified Lifecycle instance, for this web
application.
The implementation of this method must ensure that calls to the
getCurrentInstance() method of FacesContext,
from the same thread that called this method, will return the same
FacesContext instance until the release()
method is called on that instance.
The implementation must call
ExternalContextFactory#getExternalContext to produce the
ExternalContext for the FacesContext instance.
The default implementation must call
ExceptionHandlerFactory#getExceptionHandler and make it
so the return from that method is what gets returned from a call
to FacesContext#getExceptionHandler on the returned
FacesContext instance.
