Architecture

Main - entry point class. It creates main actor Master

Actors

• Master orchestrates all other specific actors and passes events between them
  • Clock heart of the system. It simulates time by Tick events.
  • MainEmitter gather events from MovementsEmitter and TurbineStatusUpdatesEmitter and emits them to Master.
  • Processors receive all events and forward to Turbines or People
    • Turbines manages fleet of turbines creates them on demand and forwards events to correct Turbine
    • Peaple creates Person on demand and forwards events to dedicated ones
  • Reminders are used indirectly by turbines to schedule some reminders
  • Logger logs errors to a file

Process

• Each emitter reads events from it's file, notifies MainEmitter when data is read.
• When all emitters are ready MainEmitter asks Master to start whole process.
• Master asks Clock to start ticking.
• Clock ticks to Master
• Master forwards ticks to MainEmitter and Reminders
• MainEmitter reacts on Ticks
• Master forwards events from MainEmitter
• MainEmitter forwards ticks to it's children
• Child emitters send events to MainEmitter
• MainEmitter forwards then to Master
• Master forwards to Processors
  • Movement events to to both Turbines and People
  • TurbineStatusUpdate events go only to Turbines
• When Turbine or Person detects tom issues it sends along parents hierarchy and Master ErrorEvents to Logger
• Logger writes them to file

Also there is some tiny logging to console. To understand what is happening.
