logger

A short dash-separated prefix that is printed before every log line. Used to uniquely identify log lines belonging to this logger from log lines belonging to others, which is especially necessary in the presence of concurrency and where logs get interleaved. Typically a single ID number or sequence of numbers.

Returns a string representation of the object.

The default representation is platform dependent.

A version of streams without the logging prefix appended to every line. Used by the logging hierarchy to print things such that the logging prefixes can be more finely customized per logger.
