  1. Think of the Magento Shop Event System. In some classes you'll find the Event Dispatcher, which dispatches a current event (say "customer_logged_in" (example, may not exist)) and with it, it'll ship the current context with it. (probably the class itself $this). 

    The event dispatcher iterates through configurated plugins/modules/extensions (whatever name you want to use) and executes their logic.

     

    Pros

    - multiple extensions can use the hook/xclass/event

    Cons

    - first come, first serve. Second in line will get already altered data. (Magento will allow you to specify dependencies in your modules configuration so you may be loaded before/after module XY)
