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 | |

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. | |
