<h2>Description</h2>
<div class="description">
<p>An implementation of <a href="Poco.Util.AbstractConfiguration.html" title="class Poco::Util::AbstractConfiguration">AbstractConfiguration</a> that stores configuration data in a directory hierarchy in the filesystem. </p>
<p>Every period-separated part of a property name is represented as a directory in the filesystem, relative to the base directory. Values are stored in files named &quot;data&quot;. </p>
<p>All changes to properties are immediately persisted in the filesystem. </p>
<p>For example, a configuration consisting of the properties </p>
<p></p>
<pre>logging.loggers.root.channel.class = ConsoleChannel
logging.loggers.app.name = Application
logging.loggers.app.channel = c1
logging.formatters.f1.class = PatternFormatter
logging.formatters.f1.pattern = [%p] %t
</pre>
<p>is stored in the filesystem as follows: </p>
