Composite Event Dispatcher-14
-----------------------------

[](#composite-event-dispatcher-14)

Install
-------

[](#install)

```
composer require symbiotic/event-dispatcher-composite

You can also put an implementation "symbiotic/event-dispatcher"
Decorator for cached events "symbiotic/event-dispatcher-cached"

```

Using the Composite Dispatcher
------------------------------

[](#using-the-composite-dispatcher)

Composite dispatcher makes it possible to process events by several Dispatchers at once.

```
/**
 * @var Psr\EventDispatcher\ListenerProviderInterface $coreProvider
 * @var Psr\EventDispatcher\ListenerProviderInterface $appProvider
 **/
$core_dispatcher = new MyEventDispatcher($coreProvider);
$app_dispatcher = new MyEventDispatcher($appProvider);

$dispatcher = new  \Symbiotic\Event\CompositeEventDispatcher();
// we add several dispatchers for processing at once
$dispatcher->attach($core_dispatcher);
$dispatcher->attach($app_dispatcher);

// Now the event will be processed by several dispatchers at once

$event = $dispatcher->dispatch(new MyEvent());
```

Composite Listener Provider
---------------------------

[](#composite-listener-provider)

It is also possible to implement event handling from multiple sources using a composition of providers. This approach is used in the framework to sequentially collect listeners in order of priority (core->application->plugin).

```
/**
 * @var Psr\EventDispatcher\ListenerProviderInterface $core_provider
 * @var Psr\EventDispatcher\ListenerProviderInterface $app_provider
 * @var Psr\EventDispatcher\ListenerProviderInterface $compositeProvider
 **/
$core_provider = new ListenerProvider();
$app_provider = new ListenerProvider();
// adding listeners to providers...

/**
 * @var Psr\EventDispatcher\ListenerProviderInterface|\Symbiotic\Event\CompositeListenersProvider $compositeProvider
 **/
$compositeProvider = new \Symbiotic\Event\CompositeListenersProvider();
$compositeProvider->attach($core_provider);
$compositeProvider->attach($app_provider);

/**
 * @var Psr\EventDispatcher\EventDispatcherInterface $dispatcher
 **/
$dispatcher = new MyEventDispatcher($compositeProvider);

$event = $dispatcher->dispatch(new MyEvent());
```
