29 | /// \brief A high performance stream decoder for muon tracking DDL streams. | |
30 | /// | |
31 | /// This is the raw stream class which interfaces between the high performance | |
32 | /// core decoder and the AliRawReader class. | |
33 | /// To gain the most out of the decoder, the Next() method which returns batches | |
34 | /// of decoded digit / channel information should be used. That is: | |
35 | /// \code | |
8a0dae7c | 36 | /// const AliBusPatch* Next(); |
e3a2b9c9 | 37 | /// \endcode |
38 | /// | |
8a0dae7c | 39 | /// This decoder tries to implement as similar an interface as possible to |
40 | /// AliMUONRawStreamTracker where possible. However certain constructs which | |
41 | /// would slow us down too much are avoided. | |
