void setLogger (const LoggerPtr &logger) override

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

void activateOptions (helpers::Pool &p) override

Activate the options that were previously set with calls to option setters.

void setOption (const LogString &option, const LogString &value) override

Set option to value.

void error (const LogString &message, const std::exception &e, int errorCode) const override

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

virtual ~ErrorHandler ()

virtual void setLogger (const LoggerPtr &logger)=0

Add a reference to a logger to which the failing appender might be attached to.

virtual void error (const LogString &message, const std::exception &e, int errorCode) const =0

Equivalent to the error(const String&, helpers::Exception&, int, spi::LoggingEvent&) with the the event parameteter set to null.

virtual void error (const LogString &message) const =0

This method is normally used to just print the error message passed as a parameter.

virtual void error (const LogString &message, const std::exception &e, int errorCode, const LoggingEventPtr &event) const =0

This method is invoked to handle the error.

virtual void setAppender (const AppenderPtr &appender)=0

Set the appender for which errors are handled.

virtual void setBackupAppender (const AppenderPtr &appender)=0

Set the appender to fallback upon in case of failure.

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.
