Detailed Description

Logger class.

The logger class handles the logging for one or more logging handlers. Each logger class instance keeps state for logging for one module or subsystem. You can add handlers to a logger which will then be used for all logging to that subsystem.

◆ handle()

void mysql_harness::logging::Logger::handle ( const Record record)

◆ is_handled()

bool mysql_harness::logging::Logger::is_handled ( LogLevel  level) const

check if the log-level will be handled.

log-messages may be filtered on global and on handler level.

in case it is not handled, there is no need call the prepare data for the log-function.

if log-level will be handled or not
Return values
truelog-level (quite likely) will be handled
falselog-level will be ignored

◆ set_level()

void mysql_harness::logging::Logger::set_level ( LogLevel  level)

◆ set_timestamp_precision()

void mysql_harness::logging::Logger::set_timestamp_precision ( LogTimestampPrecision  precision)
