Hello roottalk,
I've taken a close look at the roottalk digest, but didn't really find a
solution to my problem.
Is there a way of passing a TCut expression as argument, for example
something like:
void getSelection(TCut cut)
{
select events if "cut" is true
}
Certainly I could just use plain C++ syntax to get some selection, but my
aim is to create some environment for undergraduates to enable them to
do a simple physics analysis without any C++ knowledge, giving them some
easy to use tools for things like fitting, plotting etc... So it would be
nice if there was a way of passing cuts as an argument to a function so
that the students can define their own cuts without having to implement
root macros.
I read that TCuts are best used with TTree:Draw - but I don't see a way
how to get a selection from that.
Maybe anyone has an idea how to pass cuts to a function without using
TCuts?
Thanks a lot for your help - and have a nice weekend!
Christian
