Informations about the package events
ifcanduela/events
Simple plug-and-play events library for any kind of project.
Installation
Use Composer:
Usage
Mixin the \ifcanduela\events\CanEmitEvents or \ifcanduela\events\CanListenToEvents traits
into your classes and call the emit() or listenTo() methods.
Emitting events
An object will be able to emit events by using the CanEmitEvents trait and its
emit() method.
An event may be a simple string, or an object of a class other than stdClass.
If the event is a string, an optional $payload may be supplied and will be
sent to the listener instead of the event string.
Listening to events
An object will be able to listen to events by using the CanListenToEvents
trait and calling listenTo().
The event callback will receive the payload of the event, if any. In case of
event objects, the $payload will be the event object itself, otherwise it
will be whichever payload was passed by the emitter.
Using the EventManager directly
The event manager lets your code emit and listen to events from outside objects.
Replace $object->emit() with EventManager::trigger() and $object->listenTo()
with EventManager::register(). These two static methods are used under the
hood by the traits, so the functionality is exactly the same.
