public abstract class Lifecycle
extends java.lang.Object
Lifecycle manages the processing of the entire lifecycle of a particular Jakarta Faces request. It is responsible for executing all of the phases that have been defined by the Jakarta Faces Specification, in the specified order, unless otherwise directed by activities that occurred during the execution of each phase.
An instance of Lifecycle
is created by calling the getLifecycle()
method of
LifecycleFactory
, for a specified lifecycle identifier. Because this instance is shared across multiple
simultaneous requests, it must be implemented in a thread-safe manner.

Register a new

execute(FacesContext context)
Execute all of the phases of the request processing lifecycle, up to but not including the Render Response
phase, as described in section 2 "Request Processing Lifecycle" of the Jakarta Faces Specification Document, in the specified order.

getPhaseListeners()
Return the set of registered
PhaseListener s for this Lifecycle instance. |
abstract void |
removePhaseListener(PhaseListener listener)
Deregister an existing
PhaseListener instance that is no longer interested in being notified before and after
the processing for standard phases of the request processing lifecycle. |
abstract void |
render(FacesContext context)
Execute the Render Response phase of the request processing lifecycle, unless the
responseComplete() method has been called on the FacesContext instance associated with the
current request. |
public abstract void addPhaseListener(PhaseListener listener)
Register a new PhaseListener
instance that is interested in being notified before and after the processing
for standard phases of the request processing lifecycle.
listener
- The PhaseListener

- if listener
is null
public abstract void execute(FacesContext context) throws FacesException
Execute all of the phases of the request processing lifecycle, up to but not including the Render Response
phase, as described in section 2 "Request Processing Lifecycle" of the Jakarta Faces Specification Document, in the specified order.
The processing flow can be affected (by the application, by components, or by event listeners) by calls to the renderResponse()
or
responseComplete()
methods of the FacesContext
instance associated with the current request.
context
- FacesContext for the request to be processedFacesException
- if thrown during the execution of the request processing lifecyclejava.lang.NullPointerException
- if context
is null
public void attachWindow(FacesContext context)
Create or restore the ClientWindow
to be used to display the UIViewRoot
for
this run through the lifecycle. See the class documentation for ClientWindow
for an overview of the feature.
If ExternalContext.getClientWindow()
returns null, create a new instance of
ClientWindow
using the ClientWindowFactory
. If the result is non-null, call
ClientWindow.decode(jakarta.faces.context.FacesContext)
on it. Store the new ClientWindow
by
calling ExternalContext.setClientWindow(jakarta.faces.lifecycle.ClientWindow)
.
context
- the FacesContext
for this request.public abstract PhaseListener[] getPhaseListeners()
Return the set of registered PhaseListener
s for this Lifecycle
instance. If there are no registered
listeners, a zero-length array is returned.
PhaseListener
spublic abstract void removePhaseListener(PhaseListener listener)
Deregister an existing PhaseListener
instance that is no longer interested in being notified before and after
the processing for standard phases of the request processing lifecycle. If no such listener instance has been
registered, no action is taken.

public abstract void render(FacesContext context) throws FacesException
Execute the Render Response phase of the request processing lifecycle, unless the
responseComplete()
method has been called on the FacesContext
instance associated with the
current request.
