Class FlashFactory
- java.lang.Object
-
- javax.faces.context.FlashFactory
-
- All Implemented Interfaces:
FacesWrapper<FlashFactory>
public abstract class FlashFactory extends java.lang.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 ofFlash
.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 theFlashFactory
is used to instantiate the flash.- Since:
