## 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.

## 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 & |  | ) | 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.
