| Public Member Functions | |
|---|---|
| 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. | |

Appenders may delegate their error handling to ErrorHandlers.
Error handling is a particularly tedious to get right because by definition errors are hard to predict and to reproduce.
Please take the time to contact the author in case you discover that errors are not properly handled. You are most welcome to suggest new error handling policies or criticize existing policies.

Add a reference to a logger to which the failing appender might be attached to.
The failing appender will be searched and replaced only in the loggers you add through this method.
Parameters
| logger | One of the loggers that will be searched for the failing appender in view of replacement. |

Implemented in log4cxx::helpers::OnlyOnceErrorHandler, and log4cxx::varia::FallbackErrorHandler.
