Class SimpleLog

  org.apache.commons.discovery.log.SimpleLog

All Implemented Interfaces:

org.apache.commons.logging.Log

Deprecated. Starting from commons-discovery-05, Log is totally delegated to commons-logging

@Deprecated
public class SimpleLog
extends Object
implements org.apache.commons.logging.Log

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.
