class actor_system

Detailed Description

A registry is used to associate actors to IDs or names.

This allows a middleman to lookup actor handles after receiving actor IDs via the network and enables developers to use well-known names to identify important actors independent from their ID at runtime. Note that the registry does not contain all actors of an actor system. The middleman registers actors as needed.
