Class LifecycleWrapper

java.lang.Object

javax.faces.lifecycle.Lifecycle

javax.faces.lifecycle.LifecycleWrapper

All Implemented Interfaces:

FacesWrapper<Lifecycle>

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.

Since:

2.2

Methods

Modifier and Type	Method and Description
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.
void	attachWindow(FacesContext context) Create or restore the ClientWindow to be used to display the UIViewRoot for this run through the lifecycle.
void	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.
PhaseListener[]	getPhaseListeners() Return the set of registered PhaseListeners for this Lifecycle instance.
abstract Lifecycle	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.

Method Detail

getWrapped

public abstract Lifecycle getWrapped()

Description copied from interface: FacesWrapper

A class that implements this interface uses this method to return an instance of the class being wrapped.

Specified by:

getWrapped in interface FacesWrapper<Lifecycle>

addPhaseListener

public void addPhaseListener(PhaseListener listener)

Description copied from class: 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.

Specified by:

addPhaseListener in class Lifecycle

Parameters:

listener - The PhaseListener to be registered

execute

public void execute(FacesContext context)
             throws FacesException

Description copied from class: 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.

Specified by:

execute in class Lifecycle

Parameters:

context - FacesContext for the request to be processed

Throws:

FacesException - if thrown during the execution of the request processing lifecycle

getPhaseListeners

public PhaseListener[] getPhaseListeners()

Description copied from class: Lifecycle

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

Specified by:

getPhaseListeners in class Lifecycle

removePhaseListener

public void removePhaseListener(PhaseListener listener)

Description copied from class: 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.

Specified by:

removePhaseListener in class Lifecycle

Parameters:

listener - The PhaseListener to be deregistered

render

public void render(FacesContext context)
            throws FacesException

Description copied from class: Lifecycle

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.

Specified by:

render in class Lifecycle

Parameters:

context - FacesContext for the request being processed

Throws:

FacesException - if an exception is thrown during the execution of the request processing lifecycle

attachWindow

public void attachWindow(FacesContext context)

Description copied from class: 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).

Overrides:

attachWindow in class Lifecycle
