Detailed Description

LogControl implementation (Singleton).

Note
There is a slight difference in using the _lineFormater and _lineWriter!
  • _lineFormater must not be NULL (create default LogControl::LineFormater)
  • _lineWriter is NULL if no logging is performed, this way we can pass _no_stream as logstream to the application, and avoid unnecessary formating of logliles, which would then be discarded when passed to some dummy LineWriter.
