Class SimpleLog

java.lang.Object
org.apache.commons.discovery.log.SimpleLog
All Implemented Interfaces:
org.apache.commons.logging.Log
@Deprecated public class SimpleLog extends Object implements org.apache.commons.logging.Log
Deprecated.
Starting from commons-discovery-05, Log is totally delegated to commons-logging

Simple implementation of Log that sends all enabled log messages, for all defined loggers, to System.err.

Hacked from commons-logging SimpleLog for use in discovery. This is intended to be enough of a Log implementation to bootstrap Discovery.

One property: org.apache.commons.discovery.log.level. valid values: all, trace, debug, info, warn, error, fatal, off.
