org.apache.log4j.spi
public interface: ErrorHandler [javadoc | source]

All Implemented Interfaces:
    OptionHandler

All Known Implementing Classes:
    OnlyOnceErrorHandler, FallbackErrorHandler

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.
