Bradley Smith commented on JBSEAM-1117:

oh yes - would it be possible to allow for a single @RaiseEvent annotation to raise multiple events - i.e. an array of event values, types?

> Is it possible to make the value be based on an enum type?  I currently have all my application event types enumerated in enum called EventType.
> I've tried doing:  
> @RaiseEvent(EventType.ApplicationSaved.name())
> however, this doesn't count as a constant String and is invalid syntax.  It seems more 'elegant' to be able to enumerate the event types of an application in something like an enum than to sprinkle strings throughout the code with the specific event String values.
> Maybe an alternate annotation is called for - say, @RaiseEventType(MyEnum.MyEventType)?
> I'm not sure - I don't have a solid grasp of the syntax used to define an annotation.
