    Provides scala API for 'go-like' CSP channels.

    Provides scala API for 'go-like' CSP channels.

    Overview

    see readme for quick introduction.

    Usage

    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()
    }
  }
}

  • package channels

    Core entity is Continuated which provide iteratee-like structure for reading and writing.

    Overview

    • Input and Output provide callback-based interfaces for input/output facilities.
    • Channel provide implementation for asynchronics channels processing inside JVM.
    • SelectorBuilder is a way to create selectors.

    Internals

    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.
