javax.faces.lifecycle Class LifecycleFactory

java.lang.Object
  javax.faces.lifecycle.LifecycleFactory

public abstract class LifecycleFactory
extends Object

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);

字段摘要
`static String`	`DEFAULT_LIFECYCLE` The lifecycle identifier for the default `Lifecycle` instance for this JavaServer Faces implementation.

构造器摘要
`LifecycleFactory()`

方法摘要
`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`	`getLifecycle(String lifecycleId)` 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.

方法详细信息

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.

参数:: lifecycleId - Identifier of the new Lifecycle; lifecycle - Lifecycle instance that we are registering
抛出异常:: 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.

参数:: lifecycleId - Lifecycle identifier of the requested Lifecycle instance
抛出异常:: 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.
