public abstract class FlashFactory extends Object implements FacesWrapper<FlashFactory>
FlashFactory is a
factory object that creates (if needed) and returns Flash
instances. Implementations of JavaServer Faces must provide at
least a default implementation of Flash
.
There must be one 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 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.
