25 /// - ReadNextData to read the next raw data block (=1 DDL)
26 /// - ReadNext to read a given number of bytes
27 /// - several getters like GetType
29 /// Sequential access to the raw data is provided by the methods
30 /// ReadHeader, ReadNextData, ReadNextInt, ReadNextShort, ReadNextChar
32 /// If only data from a specific detector (and a given range of DDL numbers)
33 /// should be read, this can be achieved by the Select method.
34 /// Several getters provide information about the current event and the
35 /// current type of raw data.
