The Factory Method Pattern is a creational pattern that defines an interface for creating an object but lets subclasses decide which actual class to instantiate.
Factory方法模式是一个创建的模式,它定义一个用来创建对象的接口,而让子类来决定实例化哪个类。
In other words, Factory Method lets a class defer the instantiation to its subclasses.
换句话说,Factory方法令一个类实例化到其子类。
If the helper class is a handler factory, the GetHandler method will actually determine the type of handler to use.
如果帮助类是一个处理程序工厂,那么GetHandler方法将最终决定使用处理程序的类型。
Concrete classes provide the appropriate implementation for their respective base class. The Factory Method Pattern consists of the following classes.
concrete类为它们各自的基类提供恰当的实现。
The code in Listing 2 takes as input the actual XML instance and USES the parse method of the Factory class of AutomobilePolicyDocument to get an instance of AutomobilePolicyDocument.
清单2的代码接受输入的xml实例,并使用AutomobilePolicyDocumentFactory类的parse方法获得AutomobilePolicyDocument实例。
In Listing 2, the code first includes the necessary class file for the MDB2_Schema package, and then initializes the MDB2 abstraction layer by calling its static factory method.
在清单2中,代码首先包含了MDB2_Schema包所需的类文件,然后通过调用其静态方法factory以初始化mdb2抽象层。
To begin, the script includes the XML_Query2XML and MDB2 class files, and then initializes an instance of the MDB2 abstraction layer through its factory() method.
首先,脚本包含了 XML_Query2XML和MDB2类文件,然后通过它的factory() 方法初始化了一个 MDB2抽象层实例。
