Hi,
I am new in Akka.
Here's situation.
I am writing program which computes some math problem.
1 Experiment is computed by 1 EvaluationActor
No. of experiments might be thousands,or hundreds of thousends, even more.
Each EvaluationActor has child actor - ResultActor which collects stats
from experiment.
Now, I have EvaluationScheduler type(which's non-actor) and want to collect
stats from all experiments to show it.
According to documentation I should use Inbox class to be able to get multi
replies from ResultActors.
Here's some test code for Inbox usage :
def InboxTest = {
implicit val as = ActorSystem()
val a = actor(new Act {
become {
case "hello" ⇒ sender ! "hi"
case "hello1" ⇒ sender ! "hi1"
case "hello2" ⇒ sender ! "hi2"
}
})
implicit val i = inbox()
a ! "hello"
a ! "hello2"
a ! "hello1"
i.receive().asInstanceOf[String].foreach(print _)
print("\n")
i.receive().asInstanceOf[String].foreach(print _)
print("\n")
i.receive().asInstanceOf[String].foreach(print _)
print("\n")
The code is rough, but my thought was to show that I have to call receive()
each time I want get next message.
Since I can't get mailboxsize will be tricky to know when check for next
message.
So now, using this I need to build some mechanism to be sure that I have
all stats from each ResultActor = each experiment.
Simple solution for this is counting received messages and maybe sending
some experimentID or something.
But this's not solution, because if mailbox will be empty at I got :
java.util.concurrent.TimeoutException: deadline passed
Any better ideas/propositions?
Maybe there's better way more like "out of the box" in akka for such task?
regards
Darius.
