LifecycleFactory is a factory object that creates
(if needed) and returns
instances. Implementations of
JavaServer Faces must provide at least a default implementation of
. Advanced implementations (or external third party
libraries) MAY provide additional
(keyed by lifecycle identifiers) for performing different types of
request processing on a per-request basis.
There must be one
LifecycleFactory instance per web
application that is utilizing JavaServer Faces. This instance can be
acquired, in a portable manner, by calling:
LifecycleFactory factory = (LifecycleFactory) FactoryFinder.getFactory(FactoryFinder.LIFECYCLE_FACTORY);
The lifecycle identifier for the default
for this JavaServer Faces implementation.
Register a new
instance, associated with
lifecycleId, to be supported by this
LifecycleFactory. This method may be called at
any time, and makes the corresponding
available throughout the remaining lifetime of this web application.
Create (if needed) and return a
for the specified lifecycle identifier. The set of available
lifecycle identifiers is available via the
Each call to
getLifecycle() for the same
lifecycleId, from within the same web application,
must return the same
