0011 //  Declaration of class PHRawOManager
0012 //
0013 //  Purpose: Write a node-tree into a PRDF file
0014 //
0015 //  Description:
0016 //     - The default constructor sets all pointers to NULL. SetFile() would
0017 //       have to be called in addition.
0018 //     - The second constructor calls the setFile method to which it passes
0019 //       on its arguments. In order of appearance:
0020 //        1. The filename, type std::string, no default
0021 //        2. The runnumber, int, defaults to 0
0022 //        3. The buffersize, int, defaults to 100000
0023 //        4. The eventlength, int, defaults to -1, in which case a quarter
0024 //           of the selected buffersize will be chosen.
0025 //        5. The compression-level. Values can range between 1 and 9, as in
0026 //           gzip, the underlying compression program. Zero means no
0027 //           compression at all, default is 3.
