Events

This library includes an abstract class, Event. Event has two properties: source and when.

• source is the object from which the event originated
• when is a float containing the system time at which this event occurred.

Children of this class are passed to a Publisher, which in turn sends them to Listeners. (see Publishers and Listeners).

Here is an example concrete event class.

namespace Foobar;

use Caridea\Event\Event;

class AuthenticationEvent extends Event
{
    private $username;

    public function __construct($source, string $username)
    {
        parent::__construct($source);
        $this->username = $username;
    }

    public function getUsername(): string
    {
        return $this->username;
    }
}

You could then create a Listener that responds to Foobar\AuthenticationEvent objects.
