YAF_CONTROLLER_ABSTRACT(3)						 1						YAF_CONTROLLER_ABSTRACT(3)

The Yaf_Controller_Abstract class

INTRODUCTION

       Yaf_Controller_Abstract	is  the heart of Yaf's system. MVC stands for Model-View-Controller and is a design pattern targeted at separating
       application logic from display logic.

	Every custom controller shall inherit Yaf_Controller_Abstract.

	You will find that you can not define __construct function for your custom controller,	thus,  Yaf_Controller_Abstract	provides  a  magic
       method: Yaf_Controller_Abstract::init.

	If you have defined a init() method in your custom controller, it will be called as long as the controller was instantiated.

	Action	 may   have   arguments,   when   a  request  coming,  if  there  are  the  same  name	variable  in  the  request  parameters(see
       Yaf_Request_Abstract::getParam) after routed, Yaf will pass them to the action method (see Yaf_Action_Abstract::execute).

       Note

	       These arguments are directly fetched without filtering, it should be carefully processed before use them.
