<P>
This class is specialized in retrieving loggers by name and also
maintaining the logger hierarchy.
<p><em>The casual user does not have to deal with this class
directly.</em>
<p>The structure of the logger hierarchy is maintained by the
<A HREF="../../../org/apache/log4j/Hierarchy.html#getLogger(java.lang.String)"><CODE>getLogger(java.lang.String)</CODE></A> method. The hierarchy is such that children link
to their parent but parents do not have any pointers to their
children. Moreover, loggers can be instantiated in any order, in
particular descendant before ancestor.
<p>In case a descendant is created before a particular ancestor,
then it creates a provision node for the ancestor and adds itself
to the provision node. Other descendants of the same ancestor add
themselves to the previously created provision node.

public void <B>shutdown</B>()</PRE>
<DL>
<DD>Shutting down a hierarchy will <em>safely</em> close and remove
all appenders in all categories including the root logger.
<p>Some appenders such as <A HREF="../../../org/apache/log4j/net/SocketAppender.html" title="class in org.apache.log4j.net"><CODE>SocketAppender</CODE></A>
and <A HREF="../../../org/apache/log4j/AsyncAppender.html" title="class in org.apache.log4j"><CODE>AsyncAppender</CODE></A> need to be closed before the
application exists. Otherwise, pending logging events might be
lost.
<p>The <code>shutdown</code> method is careful to close nested
appenders before closing regular appenders. This is allows
configurations where a regular appender is attached to a logger
and again to a nested appender.
