Definition

• Events provide a simple observer implementation, allowing you to subscribe and listen for various events that occur in your application.
• Events are classes that can be fired from anywhere in your application.
• An event class will usually be bound to one, or many Events Listeners Classes or has those Listeners registered to listen to it.
• "fire" is the term that is usually used to call an Event.

Principles

• Events can be fired from Actions and or Tasks. It's preferable to choose one place only. (Tasks are recommended).
• Events SHOULD be created inside the Containers. However, general Events CAN be created in the Ship layer.

Rules

• Event classes CAN be placed inside the Containers in Events folders or on the Ship for the general Events.
• All Events MUST extend from App\Ship\Parents\Events\Event.
