25// AliTOFDigitMap class
26//
d0eb8f39 27// digitmap enables fast check if the pad was already digit.
28
29// The index of a AliTOFdigit is saved in the each digitmap "cell"
30// (there is an offset +1, because the index can be zero and zero
31// means empty cell).
bf6bf84c 32// In TOF, number of strips varies according plate type, the highest
d0eb8f39 33// number is in plate C. For all plates is used this number, so the
34// size of the digitmap is a little bit greater than necessary, but it
35// simplifies the access algorithm.
