final case class Actor[A](handler: (A) ⇒ Unit, onError: (Throwable) ⇒ Unit = ActorUtils.rethrowError)(implicit strategy: Strategy) extends Product with Serializable

Processes messages of type A, one at a time. Messages are submitted to the actor with the method !. Processing is typically performed asynchronously, this is controlled by the provided strategy.

Memory consistency guarantee: when each message is processed by the handler, any memory that it mutates is guaranteed to be visible by the handler when it processes the next message, even if the strategy runs the invocations of handler on separate threads. This is achieved because the Actor reads a volatile memory location before entering its event loop, and writes to the same location before suspending.

Implementation based on non-intrusive MPSC node-based queue, described by Dmitriy Vyukov: http://www.1024cores.net/home/lock-free-algorithms/queues/non-intrusive-mpsc-node-based-queue

A

The type of messages accepted by this actor.

handler

onError

Exception handler, called if the message handler throws any Throwable.

strategy
