Detailed Description

Our logging formatter.

We use a singleton formatter so that it can hold the current event index as an attribute and include it within the logs. This is easier than attempting to update the event number in all of the different logging sources floating around ldmx-sw.

Formatter & framework::logging::Formatter::get ( )

operator()()

void framework::logging::Formatter::operator()	(	const log::record_view &	view,
		log::formatting_ostream &	os )

format the passed record view into the output stream

The format is

[ channel ] severity : message

We de-reference the value out of the log into our own type so that we can compare and convert it into a string.
