All Implemented Interfaces:

ResultEventFactory

public class ResultObjectBasedEventFactory
extends EventFactorySupport
implements ResultEventFactory

Result object-to-event adapter interface that tries to do a sensible conversion of the result object into a web flow event. It uses the following conversion table:

Result object type	Event id	Remarks
null	EventFactorySupport.getNullEventId()
Boolean or boolean	EventFactorySupport.getYesEventId()/ EventFactorySupport.getNoEventId()
LabeledEnum	LabeledEnum.getLabel()	The result object will included in the event as an attribute named "result".
Enum	Enum.name()	The result object will included in the event as an attribute named "result".
String	The string.
Event	The resulting event object.
