Event Dispatcher Library

, _(*1)

, _(*2)

Requirements

php >= 5.6

Installation

$ composer require lucid/signal

Usage

<?php

use Lucid\Signal\EventInterface;
use Lucid\Signal\EventDispatcher;

$dispatcher = new EventDispatcher;

$dispatcher->addHandler('my_event', function (EventInterface $event) {
    // do something
});

Event Handlers

Eventhandlers can be any callable but must accept an instance of EventInterface as their first argument., _(*3)

Using handlers the implement the HandlerInterface will automatically call the handleEvent method on the handler if the event is dispatched., _(*4)

<?php

use Lucid\Signal\EventInterface;
use Lucid\Signal\HandlerInterface;
use Lucid\Signal\EventDispatcher;

class MyHandler implements HandlerInterface
{
    public function handleEvent(EventInterface $event)
    {
        // do something
    }
}

<?php

$dispatcher = new EventDispatcher;
$handler = new MyHandler;

$dispatcher->addHandler('my_event', $handler);

MyHandler::handleEvent will now be called when my_event is fired., _(*5)

Event Delegation

Events are fired subsequentially unless all handlers where adressed or until the Event object is being stopped. You can stop the eventdelegation in your handler by calling $event->stop()., _(*6)

Custom Events

Event objects can be referred to message objects. You can easily create your custom message objects by implementing the EventInterface interface or extending the Event base class., _(*7)

<?php

namespace Acme\Message;

use Lucid\Signal\Event;

class SysMessage extends Event
{
    private $message;

    public function setMessage($message)
    {
        $this->message = $message;
    }

    public function getMessage()
    {
        return $this->message;
    }
}
