Detailed Description

The log source object Contains a loglevel state and a number of data sinks for logging output, each with a loglevel threshold. When it is given output to log, it gives that output to all sinks that will accept logs equal to the current loglevel state or higher. For an example, look at the documentation for the logstream.h file.
