Hi roottalk,
I have a class:
class Record : public TNamed {
...
};
(There are also subclasses of the Record class that contain specialized data members
according to different types of record data.)
I create a TTree with one main branch to hold objects of type Record:
Record* record = 0;
tree -> Branch("record","Record",&record,16000,99);
and the main branch is split with level = 99. This splits the data members
of the TNamed class onto 2 separate branches: fName and fTitle.
My experience with the i/o of objects of this Record class to a TTree split
in this manner is that it works and I can retrieve the data stored in fName correctly.
But while researching a problem in a new record package design, related to the storage and retrieval
of TNamed data, I came upon the following roottalk digest discussion:
http://root.cern.ch/root/roottalk/roottalk00/1216.html
which indicates that splitting the TNamed data members shouldn't work. Was I just lucky when splitting
the TNamed data members in the past, or is this splitting somehow supported with
newer versions of ROOT (I'm using cvs ROOT updated last Friday)?
If the answer is that splitting of TNamed objects is not allowed, is there a way to
tell the tree->Branch method to not split the TNamed object, while still avoiding
customizing the splitlevel for the various subclasses of class Record?
Thanks for your help,
-Sue Kasahara
