Detailed Description

The OnlyOnceErrorHandler implements log4cxx'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

Member Function Documentation

error()

void log4cxx::helpers::OnlyOnceErrorHandler::error ( const LogString &  message, const std::exception &  e, int  errorCode  ) const

virtual

Prints the message and the stack trace of the exception on System.err.

Implements log4cxx::spi::ErrorHandler.

setOption()

void log4cxx::helpers::OnlyOnceErrorHandler::setOption ( const LogString &  option, const LogString &  value  )

virtual

Set option to value.

The handling of each option depends on the OptionHandler instance. Some options may become active immediately whereas other may be activated only when activateOptions is called.

Implements log4cxx::spi::OptionHandler.
