The Yaf_Plugin_Abstract class

INTRODUCTION

	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 registerd, All the methods which the  plugin  implemented
       according to this interface, will be called at the proper time.

EXAMPLES

       Example #1

	      Plugin example

	      <?php
		 /* bootstrap class should be defined under ./application/Bootstrap.php */
		 class Bootstrap extends Yaf_Bootstrap_Abstract {
		      public function _initPlugin(Yaf_Dispatcher $dispatcher) {
			  /* register a plugin */
			  $dispatcher->registerPlugin(new TestPlugin());
		      }
		 }

		 /* plugin class should be placed under ./application/plugins/ */
		 class TestPlugin extends Yaf_Plugin_Abstract {
		      public function routerStartup(Yaf_Request_Abstract $request, Yaf_Response_Abstract $response) {
			  /* before router
			     in this hook,  user can do some url rewrite */
			  var_dump("routerStartup");
		      }
		      public function routerShutdown(Yaf_Request_Abstract $request, Yaf_Response_Abstract $response) {
			  /* router complete
			     in this hook, user can do login check */
			  var_dump("routerShutdown");
		      }
		      public function dispatchLoopStartup(Yaf_Request_Abstract $request, Yaf_Response_Abstract $response) {
			  var_dump("dispatchLoopStartup");
		      }
		      public function preDispatch(Yaf_Request_Abstract $request, Yaf_Response_Abstract $response) {
			  var_dump("preDispatch");
		      }
		      public function postDispatch(Yaf_Request_Abstract $request, Yaf_Response_Abstract $response) {
			  var_dump("postDispatch");
		      }
		      public function dispatchLoopShutdown(Yaf_Request_Abstract $request, Yaf_Response_Abstract $response) {
			  /* final hoook
			     in this hook user can do loging or implement layout */
			  var_dump("dispatchLoopShutdown");
		      }
		 }

		 Class IndexController extends Yaf_Controller_Abstract {
		      public function indexAction() {
			  return FALSE; //prevent rendering
		      }
		 }

		 $config = array(
		     "application" => array(
			 "directory" => dirname(__FILE__) . "/application/",
		     ),
		 );

		 $app = new Yaf_Application($config);
		 $app->bootstrap()->run();
	      ?>

	      The above example will output something similar to:

	      string(13) "routerStartup"
	      string(14) "routerShutdown"
	      string(19) "dispatchLoopStartup"
	      string(11) "preDispatch"
	      string(12) "postDispatch"
	      string(20) "dispatchLoopShutdown"
