Design Pattern: Prototype 模式 一句话概括:用原型实例指定创建对象的种类,并且通过拷贝这个原型来创建新的对象。 您从图书馆的期刊从发现了几篇您感兴趣的文章,由于这是图书馆的书,您不可以直接在书中作记号或写字,所以您将当中您所感兴趣的几个主题影印出来,这下子您就可在影印的文章上画记重点。 Prototype模式...
1. The cloning method usually consists of just one line: running anewoperator with the prototypical version of the constructor. Note, that every class must explicitly override the cloning method and use its own class name along with thenewoperator. Otherwise, the cloning method may produce an o...

The Prototype design pattern is the one in question. It allows an object to create customized objects without knowing their class or any details of how to create them. Up to this point it sounds a lot like the Factory Method pattern, the difference being the fact that for the Factory the...
Design a "registry" that maintains a cache of prototypical objects. The registry could be encapsulated in a new Factory class, or in the base class of the "product" hierarchy. Design a factory method that: may (or may not) accept arguments, finds the correct prototype object, calls clone...
To find a field or call a method on some object, we first look in the object itself. If it has it, we’re done. If it doesn’t, we look at the object’sparent. This is just a reference to some other object. When we fail to find a property on the first object, we try its...
To create a object using either PHPBookPrototype or SQLBookPrototype we call the clone method.<?php abstract class BookPrototype { protected $title; protected $topic; abstract function __clone(); function getTitle() { return $this->title; } function setTitle($titleIn) { $this->title = ...
This pattern is used to: avoid subclasses of an object creator in the client application, like the factory method pattern does.Specify the kind of objects to create using a prototypical instance, and create new objects by copying this prototype. (使用原型实例指定将要创建的对象类型,通过复制这个...
