Class LoggerFactory

net.spy.memcached.compat.log.LoggerFactory

public final class LoggerFactory
extends Object

Factory to get logger instances. The system property net.spy.log.LoggerImpl should point to an implementation of net.spy.compat.log.Logger to use.

Depending on how and where this was compiled, a sun logger (jdk 1.4) and/or log4j logger implementation may be included. Both are included with the official distribution.
