Overview
The actor model is a mathematical model for concurrent computation. The model's primitive is the actor, which is an entity that sends and receives messages.
Concepts
Actor
An actor is a computation unit that maps each received message to:
- a finite set of messages sent to other actors.
- a new behavior - which will govern the response to the next messages.
- a finite set of new actors created.
The actor embodies all three essential elements of computation: processing, storage and communication.
An actor has an address, so other actor can send messages to it.
