Detailed Description

ConsoleAppender appends log events to std::cout or std::cerr using a layout specified by the user.

The default target is std::cout.

Properties

logToStdErr
When it is set true, the output stream will be std::cerr instead of std::cout.
ImmediateFlush
When it is set true, output stream will be flushed after each appended event.
