OnlyOnceErrorHandler Class Reference

Inherits ErrorHandler, and ObjectImpl.

List of all members.

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

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 [virtual]

Print a the error message passed as parameter 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 std::exception &  e, int  errorCode )  const [virtual]

Prints the message and the stack trace of the exception 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.
