extends Object

This class is a minimal implementation of the origianl org.apache.log4j.Logger class delegating all calls to a org.slf4j.Logger.Logger instance.

Log4j's debug(), info(), warn(), error() printing methods are directly mapped to their logback equivalents. Log4j's trace() printing method is mapped to logback's debug() method with a TRACE marker. Log4j's fatal() printing method is mapped to logback's error() method with a FATAL marker.
