java.util.logging
public class: ErrorManager [javadoc |
source]
java.lang.Object
java.util.logging.ErrorManager
Direct Known Subclasses:
InitializationErrorManager
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 logging call (who is unlikely to be interested) the Handler
should call its associated ErrorManager.

 public synchronized void error(String msg,
Exception ex,
int code) {
if (reported) {
// We only report the first error, to avoid clogging
// the screen.
return;
}
reported = true;
String text = "java.util.logging.ErrorManager: " + code;
if (msg != null) {
text = text + ": " + msg;
}
System.err.println(text);
if (ex != null) {
ex.printStackTrace();
}
}
The error method is called when a Handler failure occurs.
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. |
