Dear Rooters, Merry Christmas
Sorrowly, I do not quite understand the difference
between "delete myfile" and "myfile->Close()".
When do you usually call "myfile->Close()"?
When do you usually delete a TFile?
Looking at the source code, both TFile destructor and
TFile::Close() contain the following line:
gROOT->GetListOfFiles()->Remove(this);
This means that when I close the file, I can no longer
access it with GetListOfFiles(), although it is not
deleted. Does this mean that I have to delete the file
myself, when I call Close() because CleanUpROOTAtExit()
can no longer delete it?
The reason of asking is that from my GUI app I can
open lots of TFiles, and the question is whether I
should keep all files open during the life of my
program or if I should close/delete a TFile when I
do no longer need it?
Thank you in advance
Best regards
Christian
