Interface ErrorHandlerFactory

All Known Implementing Classes:

DefaultErrorHandlerFactory, DefaultJSPErrorHandlerFactory

public interface ErrorHandlerFactory

Users can provide their own implementation of this interface. They must, however, provide a public no-arg constructor in the implementation. The custom implementation is made available to the application through the 'error-handler-factory' init parameter. See FrontController.

An instance of a class implementing this interface is created once during FrontController initialization, and placed in the front controller context. Therefore, users should make the class thread-safe, as it will be accessed simultaneously by multiple threads.
