40 | // AliTOFHitMap class | |
41 | // | |
42 | // hitmap enables fast check if the pad was already hit | |
43 | // The index of a AliTOFSDigit is saved in the each hitmap "cell" | |
44 | // (there is an offset +1, because the index can be zero and | |
45 | // zero means empty cell. | |
46 | // In TOF, number of strips varies according plate type, the highest | |
47 | // number is in plate C. For all plates is used this number, so | |
48 | // the size of the hitmap is a little bit greater than necessary, but | |
49 | // it simplifies the access algorithm. | |
