public class NOPWriter
extends Writer

Extends Writer with methods that return immediately without doing anything. This class is used to measure the cost of constructing a log message but not actually writing to any device.

The org.apache.log4j.performance.NOPWriter class is intended for internal use only. Consequently, it is not included in the log4j.jar file.
