20 | // class for logging debug, info and error messages // | |
21 | // // | |
22 | // The AliLog class is a singleton class. It allows to steer the output // | |
23 | // level and output streams for different types of messages via static // | |
24 | // methods. // | |
25 | // // | |
26 | // It also handles the messages produces by the preprocessor macros defined // | |
27 | // in the header file: AliDebug, AliInfo, AliWarning, AliError, AliFatal. // | |
28 | // // | |
29 | // More details about the message logging can be found on the ALICE Offline // | |
30 | // web page. // | |
