Dear root expert,
I would like to ask you if you could clarify the meaning of the KEY word. For example, consider
KEY: TTree tree;4 tree
KEY: TTree tree;3 tree
- Which is the difference between tree;3 and tree;4.
- Is it true that there could be a difference in the number of events?
- Why there are 2 KEYs and which one is correct to use?
- If I want to call such a tree is it correct to use only
f->GetObject(“tree”,tree);
instead of
f->GetObject(“tree;3”,tree); or f->GetObject(“tree;4”,tree); ? - Are the same differences valid also for directory? E.G.
KEY: TDirectoryFile Selection;1
KEY: TDirectoryFile Selection;2
Thank you very much for helping.
