Detailed Description

Pure virtual base class for receiving stats from phosphor internals

Methods on this class will be called with the key and value of each stat. Callback implementations MUST NOT re-enter the TraceLog or TraceBuffer upon which it used as locks may be held when the callback is invoked.

Example usage:

class MyStatsCallback : public phosphor::StatsCallback {
     // Implement callback methods
} callback;

phosphor::TraceLog::getInstance().getStats(callback);

// Stash data as required for application
auto data = callback.getData();

Implementations should note that phosphor makes no guarantees about atomicity of the stats with respect to each other.
