php - Using vendor prefix for Twig Extension -

i trying add own extension twig. basic usage working want can call functions vendor prefix.

example: linkviewhelper:

class linkviewhelper extends \twig_extension {      public function getfunctions()     {         return array(             'link' => new \twig_filter_method(                 $this,                 'link',                 array('is_safe' => array('html'))             )         );     }      public function link($text, $uri, array $additionalparams = array(), array $atagparams = array(), $external=false)       {             $uri = $this->uri($uri, $additionalparams, $external);             // additional parsing             return $url; // somehting <a href="http://www.google.de" target="_blank">go google now!</a>       }      public function uri($uri, array $additionalparams = array(), $external = false)     {             // parsing goes here             return $uri; // http://www.google.com/     }      /**      * returns name of extension.      *      * @return string extension name      */     public function getname()     {         return 'url';     } } 

loading in bootstrap:

$this->environment->addextension(new linkviewhelper()); 

now can call function {{ link }} want call {{ url.link }}. how can achieve this?

edit: seriously, down voting question because don't understand question isn't useful @ :)

okay thought , mentioned in reply post: if set extension global, can use vendor prefix. escape return if need html stuff me have echo return instead of returning it:

  public function link($text, $uri, array $additionalparams = array(), array $atagparams = array(), $external=false)   {         $uri = $this->uri($uri, $additionalparams, $external);         // additional parsing         echo $url; // somehting <a href="http://www.google.de" target="_blank">go google now!</a>   } 

in case need isn't elegant @ all... let question open , won't mark right answer because think there have more elegant way this.

thnx @matteo bringing me global solution :)
