Design Pattern Abstract Factory

Creational Design Template

• AbstractFActory: interface declares abstract methods to create abstract products;
• ConcreteFactories: classes that implement the methods to create a product variant;
• AbstractProducts: interface declares abstract methods for a set of distinct but related product variants that make up a family of products;
• Products: classes that implement the methods to create concrete variants of the abstract product.
• Client: uses and is aware only of interfaces;

• So we can say that productA1 and productA2 are the same product but in different variants.
• Instead productA1 and productB1 are different products but of the same variant or family.
• Furthermore, AbastractProduct produces different products and ConcreteFactories determine the variant or general family to produce.

Design Pattern Abstract Factory

Modello di progettazione creazionale

• AbstractFActory: interface dichiara metodi astratti per creare prodotti astratti;
• ConcreteFactories: classi che implementano i metodi per creare una variante di prodotti;
• AbstractProducts: interface dichiara metodi astratti per un'insieme di varianti del prodotto, distinti ma corellati che costituiscono una famiglia di prodotti;
• Products: classi che implementano i metodi per realizzare varianti concrete, del prodotto astratto.
• Client: usa ed è a conoscenza solo delle interface;

• Quindi possiamo dire che productA1 e productA2 sono lo stesso prodotto ma in varianti differenti.
• Invece productA1 e productB1 sono prodotti diversi ma della stessa variante o famiglia.
• In oltre AbastractProduct produce prodotti diversi e le ConcreteFactories determinano la variante o la famiglia generale da produrre.
