Kommentarer

Ett objekt måste implementera ISponsor gränssnittet om det behöver begära en låneförnyelse för ett visst objekt. Ett objekt som implementerar ISponsor gränssnittet kan bli en sponsor genom att registrera sig med lease manager. Gränssnittet ISponsor används av livslängdstjänsten för att ringa tillbaka till sponsorn.
