Detailed Description

template<class Stream, class Area, class Level>
struct senf::log::Enabled< Stream, Area, Level >

Check, if logging is enabled for stream/area/level tuple.

This is a template meta-function which will check, whether logging to the given combination of parameters Stream, Area and Level is compile-time enabled. The logging might still be disabled at runtime.

if (senf::log::Enabled<senf::log::Debug,
                       senf::log::DefaultArea,
                       senf::log::VERBOSE>::value) {
    // ...
}

    Since the \e value member is a compile time constant, the compiler will completely optimize
    away this block of code when logging is disabled.
