Hi Rene, I do not understand reasons why fTotBytes cannot be incremented when a file is closed. I considered TBaskets as a kind of buffer for TTree, so it seems natural to empty the buffer when a file is closed and start a new buffer when the file is opened again in the same or different job. If you modify GetTotBytes to return the fTotBytes + the current buffer length, I would be satisfied - thank you. Cheers, Jiri. ************************************************************************* * E-mail address: Jiri.Chudoba@cern.ch * * WWW Homepage : http://delphiwww.troja.mff.cuni.cz/chudoba/ * * Telephone : +41 22 76 72288 * * Fax : +41 22 76 79480 * ************************************************************************* On Tue, 19 Jun 2001, Rene Brun wrote: > Hi Jiri, > TBranch::GetTotBytes returns the total number of bytes written to the file > so far, excluding the current buffer. fTotBytes cannot be incremented > when the file is closed because you may want to continue to fill the > branch in a different job. > I could modify GetTotBytes to always return the fTotBytes + the current > buffer length. > > Rene Brun > > > On Tue, 19 Jun 2001, Jiri Chudoba wrote: > > > Hello, > > > > I use TBranch::GetTotBytes() method to get a size of a given branch, but > > the result is not correct, for branches with just a few entries I get > > 0.
