Mozart 事件调度器库

这个事件库来自Mozart Small MVC框架，基于观察者模式实现。

Composer

$ curl -s http://getcomposer.org/installer | php
$ php composer.phar install

//optional create alias composer
$ ln -s composer.phar /usr/bin/composer
$ composer install
$ composer install --dev 	// dev-master
$ composer require mozart/event-dispatcher	// next typing "dev-master"

初始化类组件

<?php
require 'vendor/autoload.php'   // if youre install this library with composer
use Mozart\Library\Event\Event;
use Mozart\Library\Event\EventDispatcher;
use Mozart\Library\Event\ObjectEvent;
use Mozart\Library\Event\Listener\CustomListener;

自定义事件监听器

可选，自定义监听器以在事件上创建默认监听器名称

使用方法

-. 使用数组参数的事件

<?php

/**
 * Example Class ListenerOne { Array Argument }
 */
class ListenerOne extends CustomListener
{
    public function emailSubscriber(Event $event)
    {
        $event->setEvent(CustomListener::EVENT_SUBSCRIBER);
        echo $event->getEvent();
    }
}

$dispatcher = new EventDispatcher();

/**
 * Dispatch the event with Array Event Argument
 */
$listenerOne = new ListenerOne();
$dispatcher->addListener('event.email.subscriber', array($listenerOne, 'emailSubscriber'));
$dispatcher->dispatch('event.email.subscriber');

-. 使用闭包的事件

<?php
/**
 * Example Class ListenerTwo
 */
class ListenerTwo extends CustomListener
{
    public function newsEvent(Event $event)
    {
        $event->setEvent(CustomListener::EVENT_NEWS);
        echo $event->getEvent();
    }
}

/**
 * Dispatch the event with Closure Event Argument
 */
$dispatcher->addListener('news.event', function() {
        $listenerTwo = new ListenerTwo();
        echo $listenerTwo->newsEvent(new Event());
    });
$dispatcher->dispatch('news.event');

-. 使用对象创建自定义定义的事件

<?php
/**
 * Email Subscriber Listener
 */
class EmailSubscriberListener
{
    public function sendDelivery(ObjectEvent $event)
    {
        if (isset($event['name']) && $event['name'] === 'email.subscriber') {
            return $event['name'];
        }

        $event['send'];
    }
}
$objectEvent = new ObjectEvent(
    $subject = null, array(
        'name'  => 'email.subsciber',
        'send'  => array(
            'list'  => array(
                'faizal_pribadi@aol.com',
                'nathan_wahyudi@arcacorp.com'
            )
        )
    )
);
$dispatcher->dispatch('email.subscriber', $objectEvent);
foreach ($objectEvent['send'] as $emails => $email) {
    foreach ($email as $listEmail) {
        echo $listEmail;
    }
}

完整示例请参考示例文件夹

注入调度器

为了注入构造函数EventDispatcher

use Mozart\Library\Event\InjectDispatcher;

$inject = new InjectDispatcher($dispatcher)

PHPUnit 测试套件

$ phpunit
