ilObjSessionAccess::_checkAccess	(	$a_cmd,
		$a_permission,
		$a_ref_id,
		$a_obj_id,
		$a_user_id = `""`
	)

checks wether a user may invoke a command or not

(this method is called by ilAccessHandler::checkAccess)

@param      string          $a_cmd          command (not permission!)
@param      string          $a_permission   permission
@param      int                     $a_ref_id       reference id
