Builder模式有一个具体的术语，每个方法返回“this”吗？ [英] Is there a specific term for the Builder pattern where each method returns `this`?

问题描述

我知道这是Builder模式，但它是一种修改形式。而维基百科的生成器模式则提供了示例：

  pizzaBuilder.createNewPizzaProduct（）; 
 pizzaBuilder.buildDough（）; 
 pizzaBuilder.buildSauce（）; 
 pizzaBuilder.buildTopping（）; 
披萨p = pizzaBuilder.getPizza（）; 
  

修改后的Builder模式有一个特定的名称，如下所示：

  Pizza p = pizzaBuilder.createNewPizzaProduct（）。buildDough（）。buildSauce（）。buildTopping（）; 
  

---

最好在jQuery库中看到，您可以执行以下操作：

  $（'li.item-a'）。parent（）。css（'红色'）; 
  

其中每个方法（包括初始$（））都返回一个jQuery对象，通常代表一组页面元素，每个方法以某种方式对该集合进行操作。

解决方案

我看到这被称为生成器几个地方。

这很有意义，因为它基本上是一个 Fluent Interface 和 Builder 设计模式。

I know this is the Builder pattern, but it's a modified form of it. Whereas the Wikipedia article on Builder pattern gives the example:

pizzaBuilder.createNewPizzaProduct();
pizzaBuilder.buildDough();
pizzaBuilder.buildSauce();
pizzaBuilder.buildTopping();
Pizza p = pizzaBuilder.getPizza();

Is there a specific name for the modified Builder pattern which looks like:

Pizza p = pizzaBuilder.createNewPizzaProduct().buildDough().buildSauce().buildTopping();

---

This is best seen in the jQuery library, where you can do something like:

$('li.item-a').parent().css('background-color', 'red');

Where each method, including the initial $(), returns a jQuery object which typically represents a set of page elements, and each method operates on that set in some way.

解决方案

I've seen this called a Fluent Builder several places.

This makes a lot of sense, since it's basically a combination of a Fluent Interface and the Builder design pattern.
