Enumeration Type Documentation

enum LogLevel

levels that the user may give the log stream output in the output statement, e.g. LOG(ERROR) << "This is an error message"; DEBUGn levels appear indented by 2*n spaces in the log stream. Default level is INFO. Enumeration values: ERROR  WARNING  INFO  VERBOSE  DEBUG  DEBUG1  DEBUG2  DEBUG3  DEBUG4  DEBUG5  DEBUG6  DEBUG7  Definition at line 18 of file logstream.hpp. Referenced by Log::FromString(), LogStreamBuf::getLevel(), ConfigureLOG::Level(), and Log::ReportingLevel().
