Getting the Log Level of a Logger</h3>
The log level of a logger controls how severe a log record must be
before the logger accepts it. In particular, a log record whose level is
greater than or equal to the logger's log level is logged.
<P> A log level can be <code>null</code>, in which case the level is inherited
from the logger's parent.
<P> This example implements a method that returns the level of a
logger. If the level is <code>null</code>, the method looks for an ancestor
with a non-<code>null</code> level.
<pre>
// Return the level of the specified logger.
// If the level of logger is null, the level of the closest
// ancestor with a non-null level is returned.
public static Level getLevel(Logger logger) {
Level level = logger.getLevel();
while (level == null && logger.getParent() != null) {
logger = logger.getParent();
level = logger.getLevel();
}
return level;
}
