What object do I synchronize on in Scala?

Question

In C# it\'s pretty straightforward:

class Class1{
  private static readonly object locker = new object();
  void Method1(){
    lock(locker) { .... }
  }
}
         


        

Answer 1

In Scala it's even more straightforward to get the same behavior (I'm assuming you want to lock on the contained object for some reason e.g. more fine-grained control than locking the whole instance of that class):

class Class1 {
  private object Locker
  def method1 { Locker.synchronized { ... } }
}

But you should rarely control things this way. In particular, it won't prevent deadlocks in either C# or Scala without a lot of attention to what goes into ....

You should at least use the concurrency tools in java.util.concurrent, and you may want to look into futures or actors.
