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.
