/**
 * 

FlashFactory is a * factory object that creates (if needed) and returns {@link Flash} * instances. Implementations of JavaServer Faces must provide at * least a default implementation of {@link Flash}.

*
* *

There must be one {@link FlashFactory} instance per web * application that is utilizing JavaServer Faces. This instance can * be acquired, in a portable manner, by calling:

*
 *   FlashFactory factory = (FlashFactory)
 *     FactoryFinder.getFactory(FactoryFinder.FLASH_FACTORY);
 * 
*

The common way to access the flash instance from Java code is * still via {@link ExternalContext#getFlash}. The common way to access * the flash from Faces views is the implicit EL object "flash". The * runtime must ensure that the FlashFactory is used to * instantiate the flash.

*
* * @since 2.2 */ public abstract class FlashFactory implements FacesWrapper { public FlashFactory() { } /** *

If this factory has been decorated, the * implementation doing the decorating may override this method to provide * access to the implementation being wrapped. A default implementation * is provided that returns null.

* * @since 2.2 */ public FlashFactory getWrapped() { return null; } /** *

Create (if needed) and return a * {@link Flash} instance for this web application.

* * @param create true to create a new instance for this request if * necessary; false to return null if there's no * instance in the current session. * * @since 2.2 */ public abstract Flash getFlash(boolean create); }
