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

void activateOptions ( log4cxx::helpers::Pool &  p )

virtual

No options to activate.

Implements OptionHandler.

void addRef ( ) const

virtual

Reimplemented from ObjectImpl.

void 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 ErrorHandler.

void error ( const LogString &  message, const std::exception &  e, int  errorCode, const spi::LoggingEventPtr &  event  ) const

virtual

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

Implements ErrorHandler.

void error ( const LogString &  message ) const

virtual

Print a the error message passed as parameter on System.err.

Implements ErrorHandler.

void releaseRef ( ) const

virtual

Reimplemented from ObjectImpl.

void setAppender ( const AppenderPtr &  appender )

virtual

Does not do anything.

Implements ErrorHandler.

void setBackupAppender ( const AppenderPtr &  appender )

virtual

Does not do anything.

Implements ErrorHandler.

void setLogger ( const LoggerPtr &  logger )

virtual

Does not do anything.

Implements ErrorHandler.

void 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 OptionHandler.
