Class OnlyOnceErrorHandler

java.lang.Object

org.jboss.logging.util.OnlyOnceErrorHandler

All Implemented Interfaces:

org.apache.log4j.spi.ErrorHandler, org.apache.log4j.spi.OptionHandler

public class OnlyOnceErrorHandler
extends Object
implements org.apache.log4j.spi.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 the specified print stream.

This policy aims at protecting an otherwise working application from being flooded with error messages when logging fails.

Since:

0.9.0
