//

//  Declaration of class PHRawOManager

//

//  Purpose: Write a node-tree into a PRDF file

//

//  Description:

//     - The default constructor sets all pointers to NULL. SetFile() would

//       have to be called in addition.

//     - The second constructor calls the setFile method to which it passes

//       on its arguments. In order of appearance:

//        1. The filename, type std::string, no default

//        2. The runnumber, int, defaults to 0

//        3. The buffersize, int, defaults to 100000

//        4. The eventlength, int, defaults to -1, in which case a quarter

//           of the selected buffersize will be chosen.

//        5. The compression-level. Values can range between 1 and 9, as in

//           gzip, the underlying compression program. Zero means no

//           compression at all, default is 3.

//
