Pass TPySelector Object to tree.Process

[prdf]

Hi Wim,

Thanks for your reply.

I came across this thread which made me think passing an instance would be possible:

TPySelector usage problems

Hi all, I am trying to use a TPySelector in one of my codes and I can’t get around to make it work. What I want to to is execute a function on the selector, execute the Process function and retrieve the results. Somthing like selector = MyPySelector() selector.MyConfig() tree.Process(selector) selector.RetrieveOutput() It doesn’t work for me: TypeError: none of the 2 overloaded methods succeeded. Full details: Long64_t TTree::Process(const char* filename, Option_t* option = “”, Long64_t …

But, rereading I probably misinterpreted. However, I am in a situation where it would be very beneficial to be able to configure a very general TPySelector instance on the fly and then use this in TTree::Process. Is there some way to configure the TPySelector object without hard coding it into the module?

Thanks,

Peter
