8de97894 | 18 | // This is the base class for reading raw data and providing |

20 | // | |
42d20574 | 21 | // The derived classes, which operate on concrete raw data formats, |
22 | // should implement | |
39f9963f | 23 | // - ReadHeader to read the next (data/equipment) header |
42d20574 | 24 | // - ReadNextData to read the next raw data block (=1 DDL) |
25 | // - ReadNext to read a given number of bytes | |
26 | // - several getters like GetType | |
27 | // | |
28 | // Sequential access to the raw data is provided by the methods | |
c946ab02 | 29 | // ReadHeader, ReadNextData, ReadNextInt, ReadNextShort, ReadNextChar |
42d20574 | 30 | // |
31 | // If only data from a specific detector (and a given range of DDL numbers) | |
32 | // should be read, this can be achieved by the Select method. | |
33 | // Several getter provide information about the current event and the | |
34 | // current type of raw data. | |
