19// AliTOFDigitMap class
20//
21// digitmap enables fast check if the pad was already hit
22// The index of a AliTOFdigit is saved in the each hitmap "cell"
23// (there is an offset +1, because the index can be zero and
24// zero means empty cell.
25// In TOF, number of strips varies according plate type, the highest
26// number is in plate C. For all plates is used this number, so
27// the size of the digitmap is a little bit greater than necessary, but
28// it simplifies the access algorithm.
