java.lang.Object
org.apache.log4j.helpers.OnlyOnceErrorHandler
All Implemented Interfaces:
ErrorHandler
The
OnlyOnceErrorHandler implements log4j's default
error handling policy which consists of emitting a message for the
first error in an appender and ignoring all following errors.
The error message is printed on System.err.
This policy aims at protecting an otherwise working application
from being flooded with error messages when logging fails.
