Detailed Description

The FallbackErrorHandler implements the ErrorHandler interface such that a secondary appender may be specified.

This secondary appender takes over if the primary appender fails for whatever reason.

The error message is printed on System.err, and logged in the new secondary appender.

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 ) const [inline, virtual]

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

Implements ErrorHandler.

const AppenderPtr& getBackupAppender ( ) const [inline]

Return the backup appender.

void releaseRef ( ) const [virtual]

Reimplemented from ObjectImpl.

void setAppender ( const AppenderPtr primary) [virtual]

The appender to which this error handler is attached.

Implements ErrorHandler.

void setBackupAppender ( const AppenderPtr backup) [virtual]

Set the backup appender.

Implements ErrorHandler.

void setLogger ( const LoggerPtr logger) [virtual]

Adds the logger passed as parameter to the list of loggers that we need to search for in case of appender failure.

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.
