7 | // This is the class which is to be used during the writing of | |
8 | // simulated raw data (DDL files format). | |
9 | // It is using the root functionality in order to deal correctly | |
10 | // with little/big endian issue. By convention the detector raw | |
11 | // data payload is stored always with little endian (this corresponds | |
12 | // to the real life situation when the detector data is coming from | |
13 | // the hardware). | |
