There is a virtual method:

http://root.cern.ch/root/htmldoc/TObject.html#TObject:SavePrimitive

There are plenty of  other virtual methods:

http://root.cern.ch/root/htmldoc/TObject.html#TObject:GetObjectInfo
http://root.cern.ch/root/htmldoc/TObject.html#TObject:ShowMembers
http://root.cern.ch/root/htmldoc/TObject.html#TObject:Inspect
http://root.cern.ch/root/htmldoc/TObject.html#TObject:Browse
http://root.cern.ch/root/htmldoc/TObject.html#TObject:Draw
http://root.cern.ch/root/htmldoc/TObject.html#TObject:DrawClass
http://root.cern.ch/root/htmldoc/TObject.html#TObject:Dump
http://root.cern.ch/root/htmldoc/TObject.html#TObject:Print
http://root.cern.ch/root/htmldoc/TObject.html#TObject:Paint


STAR /Atlas use  TDataSet / TTable classes SavePrimitive methods for this purposes.
(see: http://www.usatlas.bnl.gov/computing/software/db/Chep2000.pdf  ch.2.3 for some 
 details)

    Best regards, Valeri
