Vzorec Facade zagotavlja poenostavljeni vmesnik do kompleksnega podsistema — njegova zakarivost skriva za enim čistim vhodnim točko. Zapleteno množico komponent naredi lažje uporabljivo, brez odstranitve dostopa do osnovnih podrobnosti.
Kaj vzorec Facade počne
FACADE → a SIMPLE interface in front of a COMPLEX subsystem:
→ the subsystem has many components/steps; the facade provides ONE easy interface
→ clients use the simple facade instead of dealing with the complexity directly
→ the facade coordinates the underlying components
→ HIDE complexity behind a clean, easy-to-use interface
