class AliRawReaderFile: public AliRawReader
This is a class for reading raw data files. The files of one event are expected to be in one directory. The name of the directory is "raw" + the event number. Each file contains the raw data (with data header) of one DDL. The convention for the file names is "DET_#DDL.ddl". "DET" is the name of the detector and "#DDL" is the unique equipment ID. The constructor of AliRawReaderFile takes the event number or the directory name as argument.
