Search ABAP Object

It seem that SAP does not provide built function to search for all ABAP objects in dictionary. I came up with this topic because I got one question like this: Is there any program/Tcode to querry for all object type? In Basis/Authorization module, we have Tcode SUIM (part of Information system), which allow to querry information about all users & their roles as well as authorization object. But till now, I still cannot find any similar program to find ABAP object.
