public abstract class ExternalContextFactory extends java.lang.Object implements FacesWrapper<ExternalContextFactory>
ExternalContextFactory
is a factory object that creates
(if needed) and returns new ExternalContext instances, initialized
for the processing of the specified request and response objects.
There must be one ExternalContextFactory instance per web
application that is utilizing Jakarta Server Faces. This instance can be
acquired, in a portable manner, by calling:
ExternalContextFactory factory = (ExternalContextFactory)
FactoryFinder.getFactory(FactoryFinder.EXTERNAL_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 |

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

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

If this factory has been decorated, the implementation doing the decorating may override this method to provide access to the implementation being wrapped. |
@Deprecated public ExternalContextFactory()
public ExternalContextFactory(ExternalContextFactory 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.
