Design Patterns adapter mode

25种php设计模式,你全都知道吗?下面用代码介绍适配器模式(adapter模式)

<?php
/**
 * 适配器模式
 *
 * 将一个类的接口转换成客户希望的另外一个接口,使用原本不兼容的而不能在一起工作的那些类可以在一起工作
 */
// 这个是原有的类型
class OldCache {
    public function __construct() {
        echo "OldCache construct<br/>";
    }
    public function store($key, $value) {
        echo "OldCache store<br/>";
    }
    public function remove($key) {
        echo "OldCache remove<br/>";
    }
    public function fetch($key) {
        echo "OldCache fetch<br/>";
    }
}
interface Cacheable {
    public function set($key, $value);
    public function get($key);
    public function del($key);
}
class OldCacheAdapter implements Cacheable {
    private $_cache = null;
    public function __construct() {
        $this->_cache = new OldCache();
    }
    public function set($key, $value) {
        return $this->_cache->store($key, $value);
    }
    public function get($key) {
        return $this->_cache->fetch($key);
    }
    public function del($key) {
        return $this->_cache->remove($key);
    }
}
$objCache = new OldCacheAdapter();
$objCache->set("test", 1);
$objCache->get("test");
$objCache->del("test", 1);

The difference between design patterns and architectural patterns in Java framework The difference between design patterns and architectural patterns in Java framework Jun 02, 2024 pm 12:59 PM

In the Java framework, the difference between design patterns and architectural patterns is that design patterns define abstract solutions to common problems in software design, focusing on the interaction between classes and objects, such as factory patterns. Architectural patterns define the relationship between system structures and modules, focusing on the organization and interaction of system components, such as layered architecture.

Analysis of the Decorator Pattern in Java Design Patterns Analysis of the Decorator Pattern in Java Design Patterns May 09, 2024 pm 03:12 PM

The decorator pattern is a structural design pattern that allows dynamic addition of object functionality without modifying the original class. It is implemented through the collaboration of abstract components, concrete components, abstract decorators and concrete decorators, and can flexibly expand class functions to meet changing needs. In this example, milk and mocha decorators are added to Espresso for a total price of $2.29, demonstrating the power of the decorator pattern in dynamically modifying the behavior of objects.

PHP design pattern practical case analysis PHP design pattern practical case analysis May 08, 2024 am 08:09 AM

1. Factory pattern: Separate object creation and business logic, and create objects of specified types through factory classes. 2. Observer pattern: allows subject objects to notify observer objects of their state changes, achieving loose coupling and observer pattern.

How design patterns deal with code maintenance challenges How design patterns deal with code maintenance challenges May 09, 2024 pm 12:45 PM

Design patterns solve code maintenance challenges by providing reusable and extensible solutions: Observer Pattern: Allows objects to subscribe to events and receive notifications when they occur. Factory Pattern: Provides a centralized way to create objects without relying on concrete classes. Singleton pattern: ensures that a class has only one instance, which is used to create globally accessible objects.

PHP Design Patterns: Test Driven Development in Practice PHP Design Patterns: Test Driven Development in Practice Jun 03, 2024 pm 02:14 PM

TDD is used to write high-quality PHP code. The steps include: writing test cases, describing the expected functionality and making them fail. Write code so that only the test cases pass without excessive optimization or detailed design. After the test cases pass, optimize and refactor the code to improve readability, maintainability, and scalability.

Application of design patterns in Guice framework Application of design patterns in Guice framework Jun 02, 2024 pm 10:49 PM

The Guice framework applies a number of design patterns, including: Singleton pattern: ensuring that a class has only one instance through the @Singleton annotation. Factory method pattern: Create a factory method through the @Provides annotation and obtain the object instance during dependency injection. Strategy mode: Encapsulate the algorithm into different strategy classes and specify the specific strategy through the @Named annotation.

The wonderful use of the adapter pattern in Java design patterns The wonderful use of the adapter pattern in Java design patterns May 09, 2024 pm 12:54 PM

The Adapter pattern is a structural design pattern that allows incompatible objects to work together. It converts one interface into another so that the objects can interact smoothly. The object adapter implements the adapter pattern by creating an adapter object containing the adapted object and implementing the target interface. In a practical case, through the adapter mode, the client (such as MediaPlayer) can play advanced format media (such as VLC), although it itself only supports ordinary media formats (such as MP3).

Application of design patterns in Spring MVC framework Application of design patterns in Spring MVC framework Jun 02, 2024 am 10:35 AM

The SpringMVC framework uses the following design patterns: 1. Singleton mode: manages the Spring container; 2. Facade mode: coordinates controller, view and model interaction; 3. Strategy mode: selects a request handler based on the request; 4. Observer mode: publishes and listen for application events. These design patterns enhance the functionality and flexibility of SpringMVC, allowing developers to create efficient and maintainable applications.
