The Yaf_Plugin_Abstract class

(Yaf >=1.0.0)

Giriş

Plugins allow for easy extensibility and customization of the framework.

Plugins are classes. The actual class definition will vary based on the component -- you may need to implement this interface, but the fact remains that the plugin is itself a class.

A plugin could be loaded into Yaf by using Yaf_Dispatcher::registerPlugin(), after registering, All the methods which the plugin implemented according to this interface, will be called at the proper time.
