All Superinterfaces:

ListenerInfo, NotificationBroadcaster, NotificationEmitter
```
@Taxonomy(stability=EXPERIMENTAL)
public interface LogRecordEmitter
extends NotificationEmitter, ListenerInfo
```
Emits LogRecord as JMX Notification.
The LogRecord is embedded within a Notification as follows: notif.getType() => a Notification type beginning with LOG_RECORD_NOTIFICATION_PREFIX
notif.getSource() => ObjectName of Logging MBean that emitted the Notification notif.getUserData() => Map<String,Object> with keys as described below.
To avoid deserialization problems, an actual LogRecord is not transmitted. Instead, its important fields are extracted and placed into a Map obtained as follows:
```
    final Map    fields  = (Map)notif.getUserData();
```
Alternately, you may use Util.getAMXNotificationValue(javax.management.Notification, java.lang.String) to extract any] particular field.
Valid keys within the Map are:
- LOG_RECORD_AS_STRING_KEY value is the String version of the entire LogRecord
Here is an example of how to retrieve the LogRecord information when a Notification is received:
```
final Notifcation notif = ;
final String type       = notif.getType();
final LogRecord logRecord       = (LogRecord)Util.getAMXNotificationValue(javax.management.Notification, java.lang.String)( notif, LOG_RECORD_KEY );
final String    logRecordString = (String)Util.getAMXNotificationValue(javax.management.Notification, java.lang.String)( notif, LOG_RECORD_STRING_KEY );
```
