   org.apache.log4j.Category

All known Subclasses:   org.apache.log4j.Logger,
Category
public class Category (Code)

This class is a minimal implementation of the original org.apache.log4j.Logger class by delegation of all calls to a org.slf4j.Logger.Logger instance.

Log4j's trace, debug(), info(), warn(), error() printing methods are directly mapped to their SLF4J equivalents. Log4j's fatal() printing method is mapped to SLF4J's error() method with a FATAL marker.
