[boost] [log] How to derive from a logger

22 Mar 2010

      Hi Andrey

As discussed earlier, we're kind of desperate to add functionality to a 
logger class provided by Boost.Log. Instead of duplicating 
severity_channel_logger_mt, I'm wondering whether it's a good idea to derive 
from it, as follows:

class Logger : public ::boost::log::sources::severity_channel_logger_mt< 
Severity >
{
    public:
        typedef ::boost::log::sources::severity_channel_logger_mt< Severity
...
logger_base;
        BOOST_LOG_FORWARD_LOGGER_CONSTRUCTORS(Tracer)
void SetMinimumSeverity(Severity severity);
        Severity GetMinimumSeverity();

    private:
        Severity minimumSeverity;
};

Elsewhere we'd use this class as follows:

BOOST_LOG_DECLARE_GLOBAL_LOGGER_INIT(Whatever, Logger)
{
  // ...
}

It seems to work, but is this a good idea?

Thanks & Regards,
