Simple Factory is the creation mode of a class, also known as the Static Factory method (Factory) mode.A simple factory model is a factory class that determines which product class to create based on the parameters passed in.There are 4 charactersFactory class role: A direct caller of the specific product class role.Abstract product role: an interface or abstract class that is responsible for defining specific product roles and interacting with clients.Specific product roles: objects created by

The builder pattern separates the construction of a complex object from its performance, so that the same construction process can be used to create several different manifestations.Let's look at a practical example, assuming that we want to create a HMTL page builder, the basic structure of the HTML page (the construction component) is usually the same: start HTML page generation problems can be solved using builder mode. In this model, there are two participants: the builder and the conductor

diagram is more obvious than code)I think this example is still representative, because it satisfies: "The build process can create different representations." /* "Product" */class Pizza {private String dough = ""; Private String sauce = ""; Private String topping = ""; public void Setdough (String dough) {This.dough = dough;} public void setsauce (String sauce) {this.sauce = sauce;} public void settopping (String topping) {this.topping = t

Our IT staff have more or less heard of the simple factory model, but how much he knows, we may not know for ourselves, below, let us learn some of the simple factory knowledge. 1. Simple Factory modeis a creation mode , also known as the Static factory methods (static Factory method) mode, but does not belong to one of the 23 gof design patterns. A simple factory model is a factory object that determines which product class instances are created. Simple Factory mode is the simplest and most pr

Simple Factory mode:The essence of the simple factory model is that a factory class dynamically determines which product class (these product classes inherit from a parent class or interface) should be created, based on the parameters passed in.Note: Strictly speaking, the simple Factory mode is not a design mode, but it is often used. It has the advantage of decoupling the product creation from the use of the product and processing it separately.Part of the pattern: One user: (Pizzasto

callback functions.HTTP Response ProcessingThe request may succeed or fail, ANGULARJS provides two ways to register the callback function to process two results: Success and error. All methods accept a callback function that contains the following parameters: Data: Actual return Status: HTTP state of the response headers: A function config that touches the HTTP response header: The return code of the configuration object success when the request is triggered is: 200-299, The other return codes

In the previous blog introduction to Windows Server appfabric, I briefly introduced Windows Server appfabric. This articleArticle, I will introduce how to apply wf4.0ProgramHost to Windows Server appfabric, and how to persistently configure and track the configuration. First, I will use Asp.net and wf4.0 to implement a simple pizza ordering system. Then host the application system on the Windows Server appfabric for persistence, tracking, and other

The definition of descriptor descriptors in Python: Typically, we can assume that "a property of an object is bound (__get__,__set__,__delete__Any one of these three methods ", then we call this property" descriptor "class Foo(object): def init(self, name, age): self.name = name self.age = agefoo = Foo("pizza", 18)We cannot call Foo.name, foo.age These two attributes are descriptors, because none of them are bound to the above three m

Overview STARUML is a tool that generates class diagrams and other types of Unified Modeling Language (UML) diagrams. This is a concise manual describing the creation of class diagrams in the Java language. STARUML (SU) is a tool that creates UML class diagrams and can automatically generate Java's "stub Code". Su can also do Java reverse engineering to produce the corresponding UML diagram. In this tutorial, we'll use SU to design a pizza pie. Perfo

Factory methodThe factory method uses inheritance. The object creation is delegated to the subclass, And the subclass determines which one to instantiate.Put the same method together.Abstract Product factoryMethod (String type)Factory methods are abstract;A product object must be returned;You must input a type to determine which object to create;This method is implemented after the class is inherited.Example of modifying the factory method in the workshop method mode:Put createPizza back in Pizz

Design Mode: construction mode Creational Model The generation of objects consumes system resources, so how to efficiently produce, manage, and operate objects has always been a topic worth discussing. The Creational model is related to the establishment of objects, the pattern under this classification provides some guiding principles and design directions. The list below all belongs to the Creational model. Simple Factory mode Abstract Factory mode Builder mode Factory Method mode Prototype

interaction with the Director class is the Builder class.4. Product represents the complex object being constructed. Concreatebuilder creates an internal representation of the product and defines its assembly process. /** "Product" */class Pizza {private String dough = ""; Private String sauce = ""; Private String topping = ""; public void Setdough (String dough) {This.dough = dough;} public void setsauce (String sauce) {this.sauc

The Python language has deep copy and shallow copy concepts, what is deep copy, shallow copy?Shallow copy (shallow copy): Constructs a new composite object and inserts it into the object from the reference found in the original object (that is, the address, not the content pointed to by the address) . There are many ways to implement a shallow copy, such as factory functions, slicing operations, and copy operations in the Copy module.Deep copy: Also constructs a new compound object, but encounte
