|
|
* A base class for StatusNet plugins. Mostly a light wrapper around
|
|
* the Event framework.
|
|
*
|
|
* Subclasses of Plugin will automatically handle an event if they define
|
|
* a method called "onEventName". (Well, OK -- only if they call parent::__construct()
|
|
* in their constructors.)
|
|
*
|
|
* They will also automatically handle the InitializePlugin and CleanupPlugin with the
|
|
* initialize() and cleanup() methods, respectively.
