Overview

ManagerExtractor handles SimpleDelegator subclass extraction.

Manager/delegator objects wrap a model and provide a richer interface for specific contexts (e.g., OrderManager wrapping Order with checkout-specific methods). They live in app/managers/.

We extract:

  • Wrapped model (via SimpleDelegator superclass or initializer)
  • Public methods (the manager's added interface)
  • Delegation chain (what gets delegated vs overridden)
  • Dependencies (what models/services they reference)

Examples:

extractor = ManagerExtractor.new
units = extractor.extract_all
order_mgr = units.find { |u| u.identifier == "OrderManager" }
