public abstract class FacesContextFactory extends Object implements FacesWrapper<FacesContextFactory>
FacesContextFactory is a factory object that creates (if needed) and returns new
FacesContextinstances, initialized for the processing of the specified request and response objects. Implementations may take advantage of the calls to therelease()method of the allocatedFacesContextinstances to pool and recycle them, rather than creating a new instance every time.There must be one
FacesContextFactoryinstance 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);

getWrapped
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.- Specified by:
getWrappedin interfaceFacesWrapper<FacesContextFactory>- Since:
- 2.0
-
getFacesContext
public abstract FacesContext getFacesContext(Object context, Object request, Object response, Lifecycle lifecycle) throws FacesException
Create (if needed) and return a
FacesContextinstance that is initialized for the processing of the specified request and response objects, utilizing the specifiedLifecycleinstance, for this web application.The implementation of this method must ensure that calls to the
getCurrentInstance()method ofFacesContext, from the same thread that called this method, will return the sameFacesContextinstance until therelease()method is called on that instance.The implementation must call
ExternalContextFactory.getExternalContext(java.lang.Object, java.lang.Object, java.lang.Object)to produce theExternalContextfor theFacesContextinstance.The default implementation must call
ExceptionHandlerFactory.getExceptionHandler()and make it so the return from that method is what gets returned from a call toFacesContext.getExceptionHandler()on the returnedFacesContextinstance.The default implementation must call
ClientWindowFactory.getClientWindow(javax.faces.context.FacesContext)and make it so the return from that method is what gets returned from a call toExternalContext.getClientWindow()on the returnedExternalContextinstance.- Parameters:
context- In servlet environments, theServletContextthat is associated with this web applicationrequest- In servlet environments, theServletRequestthat is to be processedresponse- In servlet environments, theServletResponsethat is to be processedlifecycle- TheLifecycleinstance being used to process this request- Throws:
FacesException- if aFacesContextcannot be constructed for the specified parametersNullPointerException- if any of the parameters arenull
