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 class="el" href="classlog4cxx_1_1_hierarchy.html#8afdd945a1581f8531c268e480ab0d86">getLogger</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.

Reset all values contained in this hierarchy instance to their default.
<p>
This removes all appenders from all categories, sets the level of all non-root categories to <code>null</code>, sets their additivity flag to <code>true</code> and sets the level of the root logger to DEBUG. Moreover, message disabling is set its default "off" value.<p>
Existing categories are not removed. They are just reset.<p>
This method should be used sparingly and with care as it will block all logging until it is completed.

<p>
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 class="el" href="classlog4cxx_1_1net_1_1_socket_appender.html">SocketAppender</a> and <a class="el" href="classlog4cxx_1_1_async_appender.html">AsyncAppender</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.
