Detailed Description

Log through multiple loggers.

It can be hand to have the opportunity to log to multiple channels, for example log to a file and via network to a remote console. This can be done with the MultiLogger. You can add an arbitrary number of loggers to log the output to. Use the minimum number of necessary loggers though because this can cause a high burden on log users if you have too many loggers.

Note that the multi logger takes over the ownership of the logger. That means that the multi logger destroys all sub-loggers when it is deleted itself. If you want to take over the loggers without destroying them you have to properly remove them before destroying the multi logger.

Constructor & Destructor Documentation

◆ MultiLogger() [1/2]

fawkes::MultiLogger::MultiLogger ( )

Constructor.

This will create the logger without any sub-loggers. Message that are logged are simply ignored.

◆ MultiLogger() [2/2]

fawkes::MultiLogger::MultiLogger ( Logger logger)

Constructor.

This sets one sub-logger that messages are sent to.

Parameters
loggersub-logger

Definition at line 86 of file multi.cpp.

◆ ~MultiLogger()

fawkes::MultiLogger::~MultiLogger ( )
virtual

Destructor.

This will destroy all sub-data->loggers (they are deleted).

Definition at line 95 of file multi.cpp.
