		public function setUrl($url){
			$this->url = $url;
		}

		public function setServer($server){
			$this->server = $server;
		}

		protected function accessServer($url){
			$ch = curl_init($url);
			curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
			$result = curl_exec($ch);
			curl_close($ch);
			return $result;
		}

		abstract protected function populate($obj);

		abstract public function execute();		

	}

			$this->setServer('http://api.facebook.com/restserver.php?method=links.getStats&urls=%s');
		}

		public function execute(){
			$url = sprintf($this->server, $this->url);
			$data = $this->accessServer($url);
			$obj  = simplexml_load_string($data);
			$this->populate($obj);
			return $this;
		}

		protected function populate($obj){
			$this->shareCount = $obj->link_stat->share_count;
			$this->likeCount = $obj->link_stat->like_count;
			$this->clickCount = $obj->link_stat->click_count;
		}
