Provides scala API for 'go-like' CSP channels.
Provides scala API for 'go-like' CSP channels.
see readme for quick introduction.
At first you must receive gopherApi as Akka extension:
import gopher._ ..... val gopherApi = Gopher(actorSystem)
Then you can use CPS channels with blocling operations inside go clauses:
val channel = gopherApi.makeChannel[Long] val n = 10000 val producer = go { @volatile var(x,y) = (0L,1L) for( s <- gopherApi.select.forever) { case z: channel.write if (z==x) => x = y y = x+z if (x > n) { channel.close implicitly[FlowTermination[Unit]].doExit() } } } val consumer = for((c,i) <- channel.zip(1 to n)) { Console.println(s"fib(${i})=${c}") } Await.ready(consumer, 10 seconds)
and defer/recover in go/goScope
goScope{
val f = openFile(myFileName)
defer{
if (! recover{case ex:FileNotFoundException => Console.println("invalid fname")}) {
f.close()
}
}
}Core entity is Continuated which provide iteratee-like structure for reading and writing.
Core entity is Continuated which provide iteratee-like structure for reading and writing. Instance of Continuated represent one step of computations and leave in queue inside ChannelProcessor or ChannelActor Selector transform Continuated to executed exclusive with each other within one selector. Also we have IdleDetector which determinate idle selectors and activer appropriative actions.
