|---|---|
| NullLoggerFactory | A logger factory that disables any logging. | 
LoggerFactory defined here is to avoid a mandatory dependency on a 3rd party
 logging system/facade. Some applications might find the events fired by the repository system sufficient and prefer
 a small footprint. Components that do not share this concern are free to ignore this package and directly employ
 whatever logging system they desire.Copyright © 2010–2018 The Apache Software Foundation. All rights reserved.
