Dear all,
I would like to perform the following operation.
I read a TTree object from a file, but, in principle, I don't know WHAT
kind of objects are stored in it. The only thing I know is that it
should contain a unique branch, called "Points".
Question 1:
I guess that I can check the existence of that branch by using
TTree::GetBranch("Points"), which should return a NULL pointer in case
that such branch does not exist. Am I right?
Question 2:
This branch should have been filled with objects if a given specified
class, say "point". How can I check if the entries stored into this
branch are of the correct type?
Thanks
alberto
