مدل Actor با استفاده از Akka.net

In the same time when first object-oriented languages were emerging, another concept inspired by general relativity and quantum mechanics was taking shape – actor model. In general terms, the Actor model was defined 1973. and was developed on a platform of multiple independent processors in a network. Similar to the object-oriented approach, this essentially mathematical model, revolved around the concept of actors. An actor is the smallest structural unit of Actor model, and just like objects, they encapsulate data and behavior. In difference to objects, however, actors communicate with each other exclusively trough messages. Messages in actors are processed in a serial manner. According to the full definition of actors, they can do three things:

  • send a finite number of messages to other actors
  • create a finite number of new actors
  • designate the behavior to be used for the next message it receives
