(Design mode) Adapter mode, design mode adapter ModeIn the adapter mode, similar to the remote control, other different button functions (interfaces) are combined, and the remote control is used for unified encapsulation to adapt to all buttons. Converts an interface of a class to another interface that the customer wa

Design Mode-singleton mode, design mode-Mode Singleton Model A class chart consists of class names, attributes, and methods. Comments starting with An underlined attribute or method indicates static. Singleton Mode features: 1. the constructor is private. 2. Only Pr

Single State mode It is not strange that public class Singleton {private Singleton () {}//define yourself an instance within yourself. Note that this is private only for internal calls private static Singleton instance = new Singleton (); This provides a static method for accessing this class externally, and you can access the public static Singleton getinstance () {return instance} directly. Factory mode

I. Overview　Concept　　　　In fact, to give a life example, adapter mode can be analogous to adapters, such as Typec and USB adaptor, the original can only be connected to Typec interface, expand to be able to connect to ordinary USB; Here the adaptor on the one hand need to check on the Typec, on the one hand need as a USB jack.If you want to cite a Java example, take a look at the JDBC Chapter! A simplified UML diagram for JDBC (the middle of the xxx JD

1. Origin In simple Factory mode, each button is packed by the Button factory class to unify all the product creation, now we put this creation to the specialized factory subclass to complete, we first define an abstract button factory class, in the definition of a factory class to generate round button, rectangular button, square button, etc. They implement the methods defined in t

Bridge definition: The separation of abstraction and behavior, independent, but dynamic combination. Why Use Bridge mode Typically, when an abstract class or interface has more than one specific implementation (concrete subclass), these concrete relationships may have the following two kinds: 1. There is a parallel between these many concrete implementations, as in the preceding example, piling, there are two concrete class: square and round piles;

Php design mode-singleton mode, php design mode-Mode For a single instance, a class provides an instance through an interface and cannot create a new instance through new or clone. The key to single-instance implementation is implemented through a static method getInstance. This method only returns the unique instanc

Stand-alone (non-distributed) mode This mode runs on a single machine without a distributed file system, but directly reads and writes to the local operating system's file system. Pseudo-distributed operation mode This mode also runs on a single machine, but uses different Java processes to mimic the various nodes in

Simple Factory pattern is the innovative model of the class, also called the Static Factory method pattern, which is responsible for creating instances of other classes by specifically defining a class that is instances that are created typically have a common parent class (or parent interface).UML diagram for simple Factory mode:(1) Abstract product role: The parent class of all objects created by the simple factory pattern, note that the parent clas

Memento definition: Memento is an object that holds a copy of the internal state of another object, so that the object can later be restored to its previously saved state. Memento mode is relatively good understanding, we look at the following code: Copy Code code as follows: public class Originator { private int number; Private file File = null; Public originator () {} Create a memento Public Memento Getmemento () { Return

About Design PatternsLet's talk about design patterns first. Many people feel that the "design pattern" is very iffy, Gof gang's "Designing Patterns" as a programming Bible, but I think it is not necessary. Design pattern plainly, is in a specific environment to solve a certain kind of common problems of a routine, according to this routine to do will be very handy. However, this does not mean that these design patterns are set on the universal, not to say that the set of design patterns to do t

In Template method mode (Templatemethod pattern), an abstract class exposes the way/template that defines the method in which it is executed. Its subclasses can override the method implementation as needed, but the invocation will be done in the way defined in the abstract class. This type of design pattern belongs to the behavioral pattern. The definition of geoscience in the design pattern is: Template method pattern: Defines the skeleton of an algo

When I learned about embedded systems, I thought about the startup process of the system on the development board. I thought about the Startup Process of the Windows system. When I looked for information about the startup process, I said that the Boot Sector is running in the real mode, then ntldr was running in the protection mode and suddenly found that I forgot about the two modes, so I found some inform

manage these communication ports to avoid a single communication port being invoked simultaneously by two requests. In short, the choice of single case mode is to avoid inconsistent state, to avoid the administration of the Bulls. One, lazy type single case[Java]View Plain copy print? Lazy Singleton class.
