Hi Ole,

You can see the list of all classes used in a TFile (typically a TTree)
with TFile::ShowStreamerInfo

You can see the top level class of a branch via
TBranchElement::GetClassName.

Currently, there is no API to see all the classes in a Tree or branch.
Note that the complete list of classes for a Tree or branch may only be
known at run time after the last TTree::Fill.
