I’m trying to write a Python script to load classes made by RooClassFactory::makePdf(). I use gROOT.LoadMacro() to load class successfully, now I want to get information about what parameters the class need. I’ve browsed all functions of RooAbsPdf and its parent classes and found nothing (maybe I missed something…)
I’ve also tried Python’s way as
and it didn’t work.
So, is there any way to know what parameters the user-made RooAbsPdf need?
ROOT Version: 6.22
@etejedor could please take a look? Thanks!
MyClass is a C++ class, right?
You can try with:
c = ROOT.TClass.GetClass("MyClass")
methods = c.GetListOfMethods()
methods is a list of
TMethod instances. You need to find in that list the constructor you are looking for and obtain the number of parameters.
Thanks a lot!
That’s quite complicated for me, as your advide I tried command below and figure it out! ( as one line)
