Psr14 Event Dispatcher

Installation
------------

[](#installation)

```
composer require entropyphp/eventdispatcher
```

Subscribe to this dispatcher
----------------------------

[](#subscribe-to-this-dispatcher)

The array keys are event names and the value can be:

The method name to call (priority defaults to 0)
The priority (default \_\_invoke class method)
The eventName (default \_\_invoke class method) (priority defaults to 0)
An array composed of the method name to call and the priority

For instance:

```
 ['eventName' => 'methodName'] //default priority 0
 ['eventName' => ListenerPriority::HIGH] //default __invoke method
 ['eventName'] //default __invoke method with default priority 0
 ['eventName' => ['methodName', ListenerPriority::HIGH]] //methodName with high priority
```

Example
-------

[](#example)

```
use Entropy\Event\EventSubscriberInterface;
use League\Event\ListenerPriority;
use Entropy\Event\EventDispatcher;

class MyListener implements EventSubscriberInterface
{
    public function __invoke(RequestEvent $event)
    {
        // Handle the event
    }

    public static function getSubscribedEvents(): array
    {
        return [
            RequestEvent::NAME => ListenerPriority::HIGH
        ];
    }
}

$dispatcher = new EventDispatcher($callableResolver);
$dispatcher->addSubscribe(MyListener::class);
```
