public abstract class Lifecycle extends Object
Lifecycle manages the processing of the entire lifecycle of a particular JavaServer Faces request. It is responsible for executing all of the phases that have been defined by the JavaServer 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.

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 to be registeredNullPointerException - if listener is nullpublic 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 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.
context - FacesContext for the request to be processedFacesException - if thrown during the execution of the request processing lifecycleNullPointerException - if context is nullpublic 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(javax.faces.context.FacesContext) on it. Store the new ClientWindow by calling ExternalContext.setClientWindow(javax.faces.lifecycle.ClientWindow).
public abstract PhaseListener[] getPhaseListeners()
Return the set of registered PhaseListeners for this Lifecycle instance. If there are no registered listeners, a zero-length array is returned.
public 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.
listener - The PhaseListener to be deregisteredNullPointerException - if listener is nullpublic 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.
