Schema Definition:The factory method pattern defines an interface for creating objects, but subclasses decide which class to instantiate.The factory method defers the instantiation of the class to the subclass.Pattern Structure:Creator is a class that implements all methods of manipulating a product, but does not implement a factory method.All subclasses of creator must implement the Factory method (FactoryMethod ()) to actually produce the product.All products must implement the product base cl

Factory mode:Defines an interface for creating an object, but its subclasses determine which object to instantiate. The factory method defers instantiation of an object to a subclass.Pattern Composition: A group of users: The parent class defines an interface for creating objects and other common interfaces, and subclasses are responsible for creating specific implementations of object interfaces (in the case Pizzastore and Nypizzastore) A set of product classes: (in the case of the

05 _ factory mode, 05 factory Mode Factory Model 1. Simple Factory: another class or object is usually used to encapsulate the instantiation operation. 2. Factory mode: The real factory mode is to define an abstract factory method and postpone the Instantiation to the subclass! (Interfaces play a key role !) Here is a simple example to illustrate how to use the factory model: Suppose you need to open several Pizza stores. Each

Simple factory mode:You can create multiple types of products based on the input parameter type.There is only one Creator method, which is used to create different products. The input parameter type is used to determine the product to be created, which is easy to implement. However, if you need to expand the product, you need to modify the implementation of the Creator method.There is a Pizza store that can produce different types of

1. PrefaceIn this blog post, we will learn how to query the data in MongoDB. When we store the data in MongoDB, we need to query the data. After all, the query operation in the crud operation is our most frequently used operation in our system. We need to deal with different business needs and construct appropriate query criteria to query the data we want. We need to learn about the syntax and functionality that MONGODB provides to us about queries. Here, we use MongoDB's own MONGO shell (MONGO

includes defining components, including interfaces for assembling these components into a final product. When creating complex objects (the building sequence between these objects is usually stable), the algorithms should be independent of the components of the objects and their assembly methods; When the constructor must allow different representations of the constructed object.
