38 | // AliMUONDigitizer should be base abstract class of all digitisers in the MUON | |
39 | // module. It implements the common functionality of looping over input streams | |
40 | // filling the fTDList and writing the fTDList to the output stream. | |
41 | // Inheriting digitizers need to override certain methods to choose and initialize | |
42 | // the correct input and output trees, apply the correct detector response if any | |
43 | // and implement how the transient digits are generated from the input stream. | |
