bea6b2a4 19///
20/// This is the base class for reading raw data.
21///
22/// The derived classes, which operate on concrete raw data formats,
23/// should implement
24/// - ReadHeader to read the next (data/equipment) header
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
28///
29/// Sequential access to the raw data is provided by the methods
30/// ReadHeader, ReadNextData, ReadNextInt, ReadNextShort, ReadNextChar
31///
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.
36///
