Class ErrorManager

java.lang.Object
  extended byjava.util.logging.ErrorManager

public class ErrorManager
extends Object

ErrorManager objects can be attached to Handlers to process any error that occur 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 the logging call (who is unlikely to be interested) the Handler should call its associated ErrorManager.

error

public void error(String msg,
                  Exception ex,
                  int code)

This method may be overriden in subclasses. The default behavior in this base class is that the first call is reported to System.err, and subsequent calls are ignored.

Parameters:
msg - a descriptive string (may be null)
ex - an exception (may be null)
code - an error code defined in ErrorManager
