ABAP-Object Services

Hello Gurus,

Can you guys enlighten me about ABAP-Object services? I've been doing ABAP objects for quite some time now. I want to know all about it (ABAP-Object services). I would like to confirm if this object is similar with the one I know in .net or in JAVA that is normally called <i><b>Class Libraries</b></i>.

Thanks!

Jeffrey
