public interface Loggable
```
This interface probes for the RuntimeLogger library by means of reflection to finally do logging. If no logger was found, then System.out and System.err are used for logging. The purpose of this interface is to provide logging facilities for low level APIs which cannot depend on the logging library as a whole.
