20 | /// | |
21 | /// Implementation of a streamer interface to the high performance trigger decoder. | |
22 | /// This is the raw stream class which interfaces between the high performance | |
23 | /// core decoder for MUON trigger chambers and the AliRawReader class. | |
24 | /// To gain the most out of the decoder, the Next() method should be used, | |
25 | /// for example: | |
26 | /// \code | |
27 | /// AliMUONRawStreamTriggerHP* rawStream; // assume initialised | |
28 | /// const AliMUONRawStreamTriggerHP::AliLocalStruct* localStruct; | |
29 | /// while ((localStruct = rawStream->Next()) != NULL) | |
30 | /// { | |
31 | /// // Do something with localStruct here. | |
32 | /// } | |
33 | /// \endcode | |
34 | /// | |
35 | /// This decoder tries to implement as similar an interface as possible to | |
36 | /// AliMUONRawStreamTrigger where possible. However certain constructs which | |
37 | /// would slow us down too much are avoided. | |
