_checkAccess()

ilObjTestAccess::_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)

Please do not check any preconditions handled by ilConditionHandler here.

Parameters

string	$a_cmd	command (not permission!)
string	$a_permission	permission
int	$a_ref_id	reference id
int	$a_obj_id	object id
int	$a_user_id	user id (if not provided, current user is taken)

Returns

boolean true, if everything is ok
