Class Lifecycle

java.lang.Object
jakarta.faces.lifecycle.Lifecycle
Direct Known Subclasses:
LifecycleWrapper
public abstract class Lifecycle extends 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.

  • Method Details

    • addPhaseListener

      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.

      Parameters:
      listener - The PhaseListener to be registered
      Throws:
      NullPointerException - if listener is null

    • execute

      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.

      Parameters:
      context - FacesContext for the request to be processed
      Throws:
      FacesException - if thrown during the execution of the request processing lifecycle
      NullPointerException - if context is null

    • attachWindow

      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).

      Parameters:
      context - the FacesContext for this request.

      2.2

    • getPhaseListeners

      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.

      Returns:
      the set of registered PhaseListeners

    • removePhaseListener

      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.

      Parameters:
      listener - The PhaseListener to be deregistered
      Throws:
      NullPointerException - if listener is null

    • render

      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.

      Parameters:
      context - FacesContext for the request being processed
      Throws:
      FacesException - if an exception is thrown during the execution of the request processing lifecycle
      NullPointerException - if context is null
