Hello *,
I'm writing an app which makes large number of histograms and some other graphs and then writes them to TFile. I'd like to avoid holding all the objects in memory, because they can be safely written to the file and discarded. I destruct all of them as soon as I don't need them, but I suppose TFile holds them somewhere in its cache. So the question is - is it possible to write a bunch of root objects into a file and discard them from memory? So the new histograms will be appended at disk to already written ones without need to hold them all in memory. I found a Flush function, but I don't know whether it's what I need.
Thanks
Best regards
