79 | * @class AliHLTLogging | |
80 | * Basic logging class. All classes inherit the besic HLT logging functionality. | |
81 | * Logging levels are controlled by a global logging filter and a local logging | |
82 | * filter. | |
83 | * | |
84 | * @section alihlt_logging_levels Logging Levels | |
85 | * Logging levels are switched by a bit pattern, AliHLTComponentLogSeverity { | |
86 | * - ::kHLTLogNone no logging (0) | |
87 | * - ::kHLTLogBenchmark benchmark messages (0x1) | |
88 | * - ::kHLTLogDebug debug messages (0x2) | |
89 | * - ::kHLTLogInfo info messages (0x4) | |
90 | * - ::kHLTLogWarning warning messages (0x8) | |
91 | * - ::kHLTLogError error messages (0x10) | |
92 | * - ::kHLTLogFatal fatal error messages (0x20) | |
93 | * - ::kHLTLogImportant few important messages not to be filtered out (0x40) | |
94 | * - ::kHLTLogAll special value to enable all messages (0x7f) | |
95 | * - ::kHLTLogDefault the default logging level: Warning, Error, Fatal, Important (0x79) | |
96 | * | |
97 | * @section alihlt_logging_filter Logging Filters | |
98 | * The class provides a global and a local logging filter, the AND beween both | |
99 | * defines whether a message is printed or not. | |
100 | * | |
101 | * The global filter is by default set to ::kHLTLogAll. Please note that AliHLTSystem | |
102 | * changes the global logging level to ::kHLTLogDefault. The global filter can be | |
103 | * adjusted by means of SetGlobalLoggingLevel(). | |
104 | * | |
105 | * The local filter is set to ::kHLTLogAll and can be adjusted by | |
106 | * SetLocalLoggingLevel(). The default can be changed for all objects by | |
107 | * SetLocalLoggingDefault(). Please note that a change of the default level only | |
108 | * applies to objects generated after the change of the default. | |
109 | * | |
110 | * @section alihlt_logging_external Redirection | |
