Best Practice width "Contextual links"

Hello,

I would like to view the report from contextual links to nodes and taxonomy when I made ​​the listing.

Not finding what to do, I create a temporary basis ...

/**
 * Contextual links
 */
function get_contextual_links($id, $type = 'node') {
  global $user;
  $output = '';
  if(!isset($user->roles[1])) { // Si utilisateur enregistré:
    
	switch($type) {
	  case 'node':
		$links = array('edit' => 'node/'.$id.'/edit', 'delete' => 'node/'.$id.'/delete');
		break;
	  case 'taxonomy':
	    $links = array('edit' => 'taxonomy/term/'.$id.'/edit');
	    break;
    }

    $items = array();
	foreach($links as $k => $v) {
	  if(menu_get_item($v)) {// Si permission
		$items[] = l(t($k), $v, array('query' => array('destination' => $_GET['q'])));
	  }
	}
		
	if($items) {
	  $output .= '<div class="contextual-links-wrapper">';
	  $theme_args = array('items' => $items, 'type' => 'ul', 'attributes' => array('class' => array('contextual-links')));
	  $output .= theme('item_list', $theme_args);
	  $output .= '</div>';
    }
  }
  return $output;
}

I think there is a more professional and easier to make and I would be interested to know. ;-)

Thank you for your help.
