Re: checking result of SetBranchAddress

I tried to code sth like this myself, but it failed (like your proposal) because of the fact that I'm using STL objects (none derived from TObject or similar), so that typeid returns rather strange names

  ( ERROR ) P2C1V3 : ROOT Does not known about: PSt6vectorIfSaIfEE

which I cannot compare against the ROOT internal names.

Which is strange because ROOT actually knows both names (-> "The pointer type give (vector<bool>) does not correspond to the class needed (vector<int>) by the branch:"), but I was not able to extract the mechanism ROOT uses to produce these messages. (It's in some function called TTree::CheckBranchAddressType.)

Could you point me to a tutorial / web page where this is described? I guess this would be the easiest way then.
