Hi all, I defined an event structure with function member like GetEnergy() returning float or int. When I store the event in a tree with the split set to 0, I can later on call the GetEnergy() method and simply histogram the return values: the call looks like that: T.Draw("event.GetEnergy()") . This is very convenient for analysis purpose since every quantity I need from an individual event, I made it a function member. My problem : when I make a typo in the function name and type for ex. T.Draw("event.Getnergy()"), it produces a segmentation fault and I loose the interactive access to the Tree object T. Is it possible to implement a check for the method being called in order to avoid such problem in case of typo? cheers, Thierry.
