concurrency - Scala: How is Barrier Synchronization implemented? -

Anyone have any idea that barrier synchronization has been implemented internally? I'm guessing that this is using semaphaurus , but I'm wondering how does it actually work, do anyone know?

I think a Samphar can create an array for each process in a simple way to consider it. Any better / more efficient implementation?

  OK, sorry for this people, I've found it after all. Here is the case that anyone is interested.  
  class barrier (n: it) {emphasis (nacety; 1); Private Enough = 0; // Waiting for the number of procedures currently waiting for the private val wa = new semaphore; WaitSem.down Personal Val mutex = new semaphore; Def Sync = {Mute x Down; If (wait == N -1) {waitSem.up; } And {wait + = 1; Mutex.up; WaitSem.down; Wait until wait -1 = 1; If (wait == 0) mutex.up; And wait em.up; }}}

Integrate flash games in android app? -



    3 is a flash game that I want to integrate into a menu / list in the Android app. So when the user selects the game from the list, the game starts with the help of the Android Flash Player.   Is it better or better with webwave?   Is there any good tutorial?   Thank you! Adobe Flash provides a good way: you can create a breeze for the Android app.    Use this to create your menu and compile three games in your air app.   Here are some tutorial links about how to publish AiI for Android applications and:   PART1: AIR for Android, PART2:   Publication for Android apps: Ai:   I do not believe that the Android Flash Player can be launched with a single intention so far, so using Java Android will not solve it (now ) And   and a third approach Whatever you mentioned, it should work - using the webwave.
