Class LifecycleFactory

java.lang.Object
javax.faces.lifecycle.LifecycleFactory
All Implemented Interfaces:
FacesWrapper<LifecycleFactory>
public abstract class LifecycleFactory extends Object implements FacesWrapper<LifecycleFactory>

LifecycleFactory is a factory object that creates (if needed) and returns Lifecycle instances. Implementations of JavaServer Faces must provide at least a default implementation of Lifecycle. Advanced implementations (or external third party libraries) MAY provide additional Lifecycle implementations (keyed by lifecycle identifiers) for performing different types of request processing on a per-request basis.

There must be one LifecycleFactory instance per web application that is utilizing JavaServer Faces. This instance can be acquired, in a portable manner, by calling:

   LifecycleFactory factory = (LifecycleFactory)
    FactoryFinder.getFactory(FactoryFinder.LIFECYCLE_FACTORY);

Usage: extend this class and push the implementation being wrapped to the constructor and use getWrapped() to access the instance being wrapped.

    Fields
    Modifier and Type
    Field
    Description
    static final String
    DEFAULT_LIFECYCLE
    The lifecycle identifier for the default Lifecycle instance for this JavaServer Faces implementation.

    Constructor
    Description
    LifecycleFactory()
    Deprecated.
    Use the other constructor taking the implementation being wrapped.
    LifecycleFactory(LifecycleFactory wrapped)
    If this factory has been decorated, the implementation doing the decorating should push the implementation being wrapped to this constructor.

    Method
    Description
    abstract void
    addLifecycle(String lifecycleId, Lifecycle lifecycle)
    Register a new Lifecycle instance, associated with the specified lifecycleId, to be supported by this LifecycleFactory.
    abstract Lifecycle

    Create (if needed) and return a Lifecycle instance for the specified lifecycle identifier.
    abstract Iterator<String>
    getLifecycleIds()
    Return an Iterator over the set of lifecycle identifiers supported by this factory.
    LifecycleFactory
    getWrapped()
    If this factory has been decorated, the implementation doing the decorating may override this method to provide access to the implementation being wrapped.

    • DEFAULT_LIFECYCLE

      public static final String DEFAULT_LIFECYCLE

      The lifecycle identifier for the default Lifecycle instance for this JavaServer Faces implementation.

      @Deprecated public LifecycleFactory()
      Deprecated.
      Use the other constructor taking the implementation being wrapped.

    • LifecycleFactory

      public LifecycleFactory(LifecycleFactory wrapped)

      If this factory has been decorated, the implementation doing the decorating should push the implementation being wrapped to this constructor. The getWrapped() will then return the implementation being wrapped.

      Parameters:
      wrapped - The implementation being wrapped.

  • Method Details

    • getWrapped

      public LifecycleFactory getWrapped()

      If this factory has been decorated, the implementation doing the decorating may override this method to provide access to the implementation being wrapped.

      Specified by:
      getWrapped in interface FacesWrapper<LifecycleFactory>
      Returns:
      the wrapped instance.
      Since:
      2.0

    • addLifecycle

      public abstract void addLifecycle(String lifecycleId, Lifecycle lifecycle)

      Register a new Lifecycle instance, associated with the specified lifecycleId, to be supported by this LifecycleFactory. This method may be called at any time, and makes the corresponding Lifecycle instance available throughout the remaining lifetime of this web application.

      Parameters:
      lifecycleId - Identifier of the new Lifecycle
      lifecycle - Lifecycle instance that we are registering
      Throws:
      IllegalArgumentException - if a Lifecycle with the specified lifecycleId has already been registered
      NullPointerException - if lifecycleId or lifecycle is null

    • getLifecycle

      public abstract Lifecycle getLifecycle(String lifecycleId)

      Create (if needed) and return a Lifecycle instance for the specified lifecycle identifier. The set of available lifecycle identifiers is available via the getLifecycleIds() method.

      Each call to getLifecycle() for the same lifecycleId, from within the same web application, must return the same Lifecycle instance.

      Parameters:
      lifecycleId - Lifecycle identifier of the requested Lifecycle instance
      Returns:
      the Lifecycle instance
      Throws:
      IllegalArgumentException - if no Lifecycle instance can be returned for the specified identifier
      NullPointerException - if lifecycleId is null

    • getLifecycleIds

      public abstract Iterator<String> getLifecycleIds()

      Return an Iterator over the set of lifecycle identifiers supported by this factory. This set must include the value specified by LifecycleFactory.DEFAULT_LIFECYCLE.

      Returns:
      an Iterator over the set of lifecycle identifiers supported by this factory
