Why TProof::SendFile is protected? How can I send a file to the workers? Suppose that during the TSelector::Process I need to read a data text file and I want to open and close it in TSelector::SlaveBegin, TSelector::SlaveTerminate. Suppose workers don’t share filesystem.
TProof::SendFile is used for internal purposes at session level.
See root.cern.ch/drupal/content/accessing-sandbox for ways to bring files to the sandbox.
