BB.Controller.Server (bb v0.15.0)

View Source

Wrapper GenServer for controller callback modules.

This module manages the lifecycle of user-defined controller modules, handling:

  • Parameter reference resolution at startup
  • Subscription to parameter changes
  • Delegation of GenServer callbacks to user module
  • Optional safety registration (only if controller implements disarm/1)

User modules implement the BB.Controller behaviour and define callbacks. This server wraps them, providing the actual GenServer implementation.
