php Prototype原型模式学习笔记

<?php

//机兵类

class Marine

{

  //所属的用户ID

  public $playerID

  //构造函数，参数为用户的id

  public function __construct($id)

  {

  $this->playerID = $id;

  }

}

//兵种的管理类

class TroopManager

{

  //数组，用于存放多个兵种的原型

  public $troopPrototype = array();

  //增加原型，第一个参数为原型的名字，第二个参数为原型对象

  public function addPrototype($name, $prototype)

  {

    $this->troopPrototype[$name] = $prototype;

  }

  //获取原型的克隆，也就是替代new的方法，参数为原型的名字

  public function getPrototype($name)

  {

    return clone $this->troopPrototype[$name];

  }

}

//初始化兵种的管理类

$manager = new TroopManager();

//初始化两个属于不同玩家的机兵的原型

$m1 = new Marine(1);

$m2 = new Marine(2);

//增加原型，同时用比较容易记忆的名字来命名原型

$manager->addPrototype('Marine of 1', $m1);

$manager->addPrototype('Marine of 2', $m2);

//当需要新增对象的时候，我们可以不必知道对象的类名和初始化的工作

$m3 = $manager->getPrototype('Marine of 1');
