Meta programming in WordPress here we go... Automatic registration of methods as wp_ajax_* hook callbacks via @wpajax annotation. No more manual listing hooks and callbacks in the old WP way

AdminAjax.php

<?php
  
  	/**
	 * Registers all ajax hooks
	 * The method which suppose to be wp_ajax_* callback must have @WpAjax annotation
	 */
	public static function registerAjaxHooks()
	{
		$methods = get_class_methods(__CLASS__);
		$r = new NClassReflection(__CLASS__);

		foreach($methods as $method){
			if($r->getMethod($method)->getAnnotation('WpAjax'))
				add_action("wp_ajax_{$method}", array(__CLASS__, $method));
		}
	}



	/**
	 * Saves Theme Options
	 * Will be called as do_action("wp_ajax_saveThemeOptions")
	 * 
	 * @WpAjax
	 */
	public static function saveThemeOptions()
	{
		// code...
		exit;
