The EventManager is a component designed for the following use cases:
* Implementing simple subject/observer patterns.
* Implementing Aspect-Oriented designs.
* Implementing event-driven architectures.
The basic architecture allows you to attach and detach listeners to named events, both on a per-instance basis as well as via shared collections; trigger events; and interrupt execution of listeners.
Quick Start : Typically, you will compose an EventManager instance in a class.
use Zend\EventManager\EventManagerInterface;
use Zend\EventManager\EventManager;
use Zend\EventManager\EventManagerAwareInterface;
class Foo implements EventManagerAwareInterface
{
protected $events;
public function setEventManager(EventManagerInterface $events)
{
$events->setIdentifiers(array(
__CLASS__,
get_called_class(),
));
$this->events = $events;
return $this;
}
public function getEventManager()
{
if (null === $this->events) {
$this->setEventManager(new EventManager());
}
return $this->events;
}
}
