It is possible that several received messages match in Akka FSM
Is it possible to match multiple messages in one case / Event using Akka FSM event function. Meaning I would like to collapse two events into one.
case Event(response : GoodResponse, session:CustomerSession) =>
case Event(response : Timeout, session:CustomerSession) =>
case Event(response : Rejected, session:CustomerSession) =>
will become something like
case Event(response : GoodResponse, session:CustomerSession) =>
case Event(response : Timeout || response : Rejected , session:CustomerSession) =>
Both error cases call the same handling function and return the same result, so I'd rather advertise this fact with event handling
You can simply have Timeout
and Rejected
implement the same feature and match that feature.
If, as you write in the comment, you cannot change the Timeout and Rejected types / implementation, you can use a case that simply ignores the type. This should work if you've done all the other stuff before. I would look like
case Event(response : GoodResponse, session:CustomerSession) =>
case Event(response : _, session:CustomerSession) =>
I'm not sure if I have the syntax on the right, but something along this line should work.
Another option is to define a custom extractor, for example:
object RejectedOrTimeout{
def unapply(value:Any) = {
if (value.isInstanceOf[Rejected] || value.isInstanceOf[Timeout]) Some(value)
else None
}
}
And then use it in your conformance assertion like this:
case Event(RejectedOrTimeout(response), session:CustomerSession) =>
