All Implemented Interfaces:
OptionHandler, Appender
A bogus appender which calls the format method of its layout object
but does not write the result anywhere.
The
org.apache.log4j.performance.NullAppender class is
intended for internal use only. Consequently, it is not
included in the log4j.jar file.
