    e390.  
    Preventing a Logger from Forwarding Log Records to its Parent</h3>

By default, a logger sends a log record not only to its handlers but
to all the handlers of ancestor loggers.  If the effects
of the parent handlers are not desired, it is necessary to prevent log
records from being forwarded to the parent.

<P> This example demonstrates how to stop a logger from sending
log records to its parent.

<P> Note: Although the level of a log record is tested against the
logger's log level, this test is not done with any of the logger's
parents.  However, the log level of all handlers is still in
effect.


<pre>
    // Get a logger
    Logger logger = Logger.getLogger(<font color="#0066ff"><i>"com.mycompany"</i></font>);
    
    // Stop forwarding log records to ancestor handlers
    logger.setUseParentHandlers(false);
    
    // Start forwarding log records to ancestor handlers
    logger.setUseParentHandlers(true);
