Class ErrorManager
- java.lang.Object
-
- java.util.logging.ErrorManager
public class ErrorManager extends Object
ErrorManager objects can be attached to Handlers to process any error that occurs on a Handler during Logging.
When processing logging output, if a Handler encounters problems then rather than throwing an Exception back to the issuer of the logging call (who is unlikely to be interested) the Handler should call its associated ErrorManager.
