Creating a single shared 'manager' for your business objects allows you to centralize and standardize all you your instance list activities to avoid repeating code in your filters or command handlers.
Using a shared manager, you can:
- Create shared methods and make them available to all your filters and command handlers
- Delegate activities to the manager
- Manage the notification of events performed by filters and command handlers
