Hello,
Below you will find a part of an initialisation of a Monte Carlo Tree
Hit processing. The Tree Branch has been created acoording to the "Post
a List in a Folder" technics.
My first question concerns the possibility to create automatically the
Folder hierachy (instead of calling the routine createFolder which
makes the job) following the name of the branch that is coded in the
FindBranch method: .topFold.RunMC.EventMC.Hits.MCHitList. At the most
convenient it would be nice to just call FindBranch("MCHitList") and if
there is no ambiguity (this is the responsaboility of the code
developper) then the Folder hierarchy can be infered and created?
My second question concerns the MakeClass in an interactive Root
session, reading such Tree is it now with root 3.03/05 possible to
generate automatically a code that make access to the elements of the
List in the branch?
Regards
J.E Campagne

m_status = BaseStorage::FATAL;
}
//create Hit List
m_mcHitList = new TList();
m_mcHitList->SetName("MCHitList");
//Get the Tree of the MC hits
if (!m_treeMCH) {
cout << "RootStorage: No TreeMCH in file " << m_fileIn->GetName() << endl;
m_status = BaseStorage::FATAL;
}
//How to avoid this hard coding style...
m_branchMCH = m_treeMCH->FindBranch(".topFold.RunMC.EventMC.Hits.MCHitList");
if (!m_branchMCH){
cout << "RootStorage: Cannot retreive MCM branch " << endl;
m_status = BaseStorage::FATAL;
}
