public abstract class LifecycleWrapper extends Lifecycle implements FacesWrapper<Lifecycle>
Provides a simple implementation of
Lifecycle
that can be subclassed by developers wishing to
provide specialized behavior to an existing Lifecycle
instance. The default implementation of all methods is to call
through to the wrapped Lifecycle
.
Usage: extend this class and override getWrapped() to return the instance we are wrapping.

addPhaseListener(PhaseListener listener)
Register a new

the request processing lifecycle. |

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 the JavaServer Faces Specification, in the specified
order.

getPhaseListeners()
Return the set of registered
PhaseListener s for this
Lifecycle instance. |

getWrapped()
A class that implements this interface uses this method to return an instance of the class being wrapped. |
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. |
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 void addPhaseListener(PhaseListener listener)
Lifecycle
Register a new PhaseListener
instance that is interested in
being notified before and after the processing for standard phases of
the request processing lifecycle.

Lifecycle
Execute all of the phases of the request processing lifecycle,
up to but not including the Render Response phase,
as described in the JavaServer Faces Specification, 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.

Lifecycle
Return the set of registered PhaseListener
s for this
Lifecycle
instance. If there are no registered listeners,
a zero-length array is returned.

public void removePhaseListener(PhaseListener listener)
Lifecycle
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.

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.

Lifecycle
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(javax.faces.context.FacesContext)
on it.
Store the new ClientWindow
by calling
ExternalContext.setClientWindow(javax.faces.lifecycle.ClientWindow)
.
