// All `RTCStats` classes should use these macros. // `WEBRTC_RTCSTATS_DECL` is placed in a public section of the class definition. // `WEBRTC_RTCSTATS_IMPL` is placed outside the class definition (in a .cc). // // These macros declare (in _DECL) and define (in _IMPL) the static `kType` and // overrides methods as required by subclasses of `RTCStats`: `copy`, `type` and // `AttributesImpl`. The |...| argument is a list of addresses to each attribute // defined in the implementing class. The list must have at least one attribute. // // (Since class names need to be known to implement these methods this cannot be // part of the base `RTCStats`. While these methods could be implemented using // templates, that would only work for immediate subclasses. Subclasses of // subclasses also have to override these methods, resulting in boilerplate // code. Using a macro avoids this and works for any `RTCStats` class, including // grandchildren.) // // Sample usage: // // rtcfoostats.h: // class RTCFooStats : public RTCStats { // public: // WEBRTC_RTCSTATS_DECL(); // // RTCFooStats(const std::string& id, Timestamp timestamp); // // std::optional<int32_t> foo; // std::optional<int32_t> bar; // }; // // rtcfoostats.cc: // WEBRTC_RTCSTATS_IMPL(RTCFooStats, RTCStats, "foo-stats" // &foo, // &bar); // // RTCFooStats::RTCFooStats(const std::string& id, Timestamp timestamp) // : RTCStats(id, timestamp), // foo("foo"), // bar("bar") { // } //
