[Zope] Get object by object id

What is the easiest way to get an object value given the object id? There is an API method objectValues('MetaType'), but I couldn't find a method analogous to getObject(objectId). Currently I'm getting all objects in the container with objectValues() and then iterating through them checking their id until I find the needed object. I suspect there is a better way that I'm not aware of. Any suggestions? --Borislav
