public abstract class FacesContextFactory extends java.lang.Object implements FacesWrapper<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 Jakarta Server
Faces. This instance can be acquired, in a portable manner, by calling:
FacesContextFactory factory = (FacesContextFactory) FactoryFinder.getFactory(FactoryFinder.FACES_CONTEXT_FACTORY);
Usage: extend this class and push the implementation being wrapped to the constructor and use getWrapped()
to
access the instance being wrapped.
Constructor and Description |

FacesContextFactory()
Deprecated.
Use the other constructor taking the implementation being wrapped.

FacesContextFactory(FacesContextFactory wrapped)
If this factory has been decorated, the implementation doing the decorating should push the implementation being wrapped to this constructor. |

specified Lifecycle instance, for this web application. |

public FacesContextFactory(FacesContextFactory 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.

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(java.lang.Object, java.lang.Object, java.lang.Object)
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.
The default implementation must call ClientWindowFactory.getClientWindow(jakarta.faces.context.FacesContext)
and make it
so the return from that method is what gets returned from a call to ExternalContext.getClientWindow()
on the
returned ExternalContext
instance.
