Detailed Description

Implementation of the logger singleton.

The logger will gather the messages inside LoggerImpl::_messages until the LoggerImpl::setOutput() is called and the sink is set. After start the logs will be redirected to sink while it's functional.

If the sink becomes unavailable the log messages are collected inside the LoggerImpl::_messages again and may possibly lead to large memory usage.

static

Access point to the singleton

log()

void logging::LoggerImpl::log

(

const LogMessage &&

msg

)

Just pushs the msg to the _messages queue

operator=() [1/2]

setOutput()

void logging::LoggerImpl::setOutput

(

const std::shared_ptr< LogSink > &

output

)

Switch on output and start logging.

Parameters

output

The prepared logging::LogSink to write the logs.

writeOut()

void logging::LoggerImpl::writeOut ( )

private

The main thread function for the output.

Pops out the messages from the thread and calls LoggerImpl::_sink->write()
