def self.actor_suffix(value)
  value.to_s.downcase.gsub(/[^a-z0-9]+/, '_').gsub(/\A_+|_+\z/, '')
end

.build_actors ⇒ Object

Called by the framework during autobuild. Runs normal actor discovery, then replaces the single ModelWorker entry with one concrete subclass per subscription entry in settings (each has a zero-arg initialize).
