Virtual Constructor虛擬構(gòu)造器

Intent意圖

Define an interface for creating an object, but let subclasses decide which class to instantiate. Factory Method lets a class defer instantiation to subclasses.定義一個(gè)接口[可以是抽象類或者接口]用來(lái)創(chuàng)建對(duì)象,，而且讓子類決定哪個(gè)類來(lái)實(shí)例化。工廠方法模式讓一個(gè)類委托實(shí)例化給子類,。

Explanation解釋

Real world example真實(shí)例子

Blacksmith manufactures weapons. Elves require Elvish weapons and orcs require Orcish weapons. Depending on the customer at hand the right type of blacksmith is summoned.鐵匠制造武器,。精靈需要精靈型武器；獸人需要獸人型武器,。什么類型鐵匠被召喚取決于客戶端,。

In plain words直白解釋

It provides a way to delegate the instantiation logic to child classes.工廠方法模式提供了一種委托實(shí)例化邏輯給子類的方式。
