Events allow easy setup and use for communication between components in application. Event can notify about state changes and pass data of any kind.

### Installation

[](#installation)

Via [composer](https://getcomposer.org/)

```
composer require actualwave/events

```

### Usage

[](#usage)

To use events you don't need to implement any interfaces, just create `EventDispatcher`and register some listeners for events.

```
class Broadcaster {
  const EVENT_FIRST = 'eventFirst';
  const EVENT_SECOND = 'eventSecond';
  const EVENT_THIRD = 'eventThird';
  /**
   * @var \aw\events\EventDispatcher
   */
  private $_dispatcher;

  //TODO add dispatcher target test
  public function __construct() {
    $this->_dispatcher = new \aw\events\EventDispatcher();
  }

  public function addHandler(string $eventType, callable $handler) {
    $this->_dispatcher->addEventListener($eventType, $handler);
  }

  public function doFirst() {
    echo 'do first and tell ';
    $this->_dispatcher->dispatchEvent(self::EVENT_FIRST);
  }

  public function doSecond() {
    echo 'do second and tell ';
    $this->_dispatcher->dispatchEvent(new \aw\events\ValueEvent(self::EVENT_SECOND, 'pass some data'));
  }

  public function doThird() {
    echo 'do third and tell ';
    $this->_dispatcher->dispatchEvent(self::EVENT_THIRD);
  }
}
```

After `EventDispatcher` is instantiated, you can add listeners and dispatch events.

```
$target = new Broadcaster();
// register event handlers
$target->addHandler(Broadcaster::EVENT_FIRST, function ($event) {
  echo $event->type . PHP_EOL;
});

function secondHandler($event) {
  echo 'handler was called with data: '.$event->value.PHP_EOL;
}

$target->addHandler(Broadcaster::EVENT_SECOND, 'secondHandler');
$target->addHandler(Broadcaster::EVENT_THIRD, [new class () {
  public function eventHandler($event) {
    echo 'event has target: '.json_encode(isset($event->target)).PHP_EOL;
  }
}, 'eventHandler']);
// broadcast events
$target->doThird(); // do third and tell event has target: true
$target->doSecond(); // do second and tell handler was called with data: pass some data
$target->doFirst(); // do first and tell eventFirst
```
