Detailed Description

The TreeStreamRedirector class manages one or few TreeStream objects to be written to the same output file. TreeStreamRedirector myTreeStreamRedirector("myOutFile.root","recreate"); myTreeStreamRedirector<<"myStream0"<<"brName00="<<obj00<<"brName01="<<obj01<<"\n"; ... myTreeStreamRedirector<<"myStream2"<<"brName10="<<obj10<<"brName11="<<obj11<<"\n"; ... will create ouput file with 2 trees stored.

The flushing of trees to the file happens on TreeStreamRedirector::Close() call or at its desctruction.

See testTreeStream.cxx for functional example
