neat / event example snippets

// First create your container (used for event dispatching and dependency injection)
$container = new Neat\Service\Container();

// The dispatcher will need a service container for dependency injection
$dispatcher = new Neat\Event\Dispatcher($container);

// A generic event can be defined using a simple PHP class without any members
class SomeEvent
{
}

// Specific events may also use inheritance using extends or interfaces
class SomeSpecificEvent extends SomeEvent
{
}

// Implement the Stoppable event interface if you want control over dispatching your event
class SomeStoppableEvent implements Neat\Event\Stoppable
{
    public function isPropagationStopped(): bool
    {
        return random_int(0, 1) == 1;
    }
}

// Now listen for events of this class or any of its subclasses or implementations
$dispatcher->listen(SomeEvent::class, function (SomeEvent $event) {
    // ...
});

// Or for a specific event
$dispatcher->listen(SomeSpecificEvent::class, function (SomeSpecificEvent $event) {
    // ...
});

// This will trigger only the SomeEvent listener, NOT the SomeSpecificEvent listener
$dispatcher->dispatch(new SomeEvent());

// This will trigger both the SomeEvent and SomeSpecificEvent listeners
$dispatcher->dispatch(new SomeSpecificEvent());
