【風(fēng)趣的解釋】

Abstract Factory Mode

請(qǐng)美眉去麥當(dāng)勞吃漢堡，不同的美眉有不同的口味，要每個(gè)都記住是一件煩人的事情，我一般采用Factory Method Mode，帶著美眉到服務(wù)員那兒，說“要一個(gè)漢堡”，具體要什么樣的漢堡呢，讓美眉直接跟服務(wù)員說就行了。

【正式的解釋】

抽象工廠模式

核心工廠類不再負(fù)責(zé)所有產(chǎn)品的創(chuàng)建，而是將具體創(chuàng)建的工作交給子類去做，成為一個(gè)抽象工廠角色，僅負(fù)責(zé)給出具體工廠類必須實(shí)現(xiàn)的接口，而不接觸哪一個(gè)產(chǎn)品類應(yīng)當(dāng)被實(shí)例化這種細(xì)節(jié)。
