+ <p>
+ In its default mode of operation Commons Configuration supports retrieving and storing
+ configuration files either on a local file system or via http. However, Commons
+ Configuration provides support for allowing other File System adapters. All file
+ access is accomplished through the <code>FileSystem</code> interface so accessing files
+ using other mechanisms is possible.
+ </p>
+ <p>
+ Commons Configuration also provides a second FileSystem which allows retrieval using
+ <a href="http://commons.apache.org/vfs">Apache Commons VFS</a>. As of this writing
+ Commons VFS supports 18 protocols for manipulating files.
+ </p>
+ <subsection name="Configuration">
+ <p>
+ The FileSystem used by Commons Configuration can be set in one of several ways:
+ <ol>
+ <li>A system property named "org.apache.commons.configuration.filesystem" can be defined
+ with the full class name of the desired <code>FileSystem</code> implementation to set the
+ default <code>FileSystem</code>.</li>
+ <li><code>FileSystem.setDefaultFilesystem()</code> can be called to directly set the
+ default <code>FileSystem</code> implementation.</li>
+ <li><code>DefaultConfigurationBuilder.setFileSystem()</code> can be called to set the
+ FileSystem implementation. <code>DefaultConfiguratonBuilder</code> will use this for each
+ configuration it creates</li>
+ <li><code>DefaultConfigurationBuilder</code> can be configured with the <code>FileSystem</code>
+ to be used when creating each of the configurations.</li>
+ <li>Each Configuration referenced in <code>DefaultConfigurationBuilder's</code>
+ configuration can be configured with the <code>FileSystem</code> to use for that
+ configuration.</li>
+ <li>Call setFileSystem() directly on any Configuration that implements <code>FileSystemBased.</code>
+ Both <code>AbstractFileConfiguration</code> and <code>AbstractHierarchicalFileConfiguration</code>
+ implement <code>FileSystemBased</code></li>
+ </ol>
+ </p>
+ <p>
+ The example that follows shows how to add <code>FileSystem</code> configuration to
+ <code>DefaultConfigurationBuilder</code>.

+ </subsection>
+ <subsection name="File Options Provider">
+ <p>
+ Commons VFS allows options to the underlying file systems being used. Commons Configuration
+ allows applications to provide these by implementing the <code>FileOptionsProvider</code> interface
+ and registering the provider with the <code>FileSystem</code>. <code>FileOptionsProvider</code>
+ has a single method that must be implemented, <code>getOptions</code>, which returns a Map
+ containing the keys and values that the <code>FileSystem</code> might use. The getOptions
+ method is called as each configuration uses VFS to create a <code>FileOjbect</code> to
+ access the file. The map returned does not have to contain the same keys and/or values
+ each time it is called. For example, the value of the <code>currentUser</code> key can be
+ set to the id of the currently logged in user to allow a WebDAV save to record the userid
+ as a file attribute.
+ </p>
+ </subsection>
+ <subsection name="File Reloading Strategy">
+ <p>
+ The <code><a href="../apidocs/org/apache/commons/configuration/reloading/VFSFileMonitorReloadingStrategy.html">VFSFileMonitorReloadingStrategy</a></code>
+ can be used to cause Configurations accessed via the <code>VFSFileSystem</code> to be
+ monitored and reloaded when the files are modified. The example below shows how
+ <code>DefaultConfigurationBuilder</code> can be configured to use
+ <code>VFSFileMonitorReloadingStrategy</code>. While each declaration will result in
+ a new reloading strategy object, each instance will share a common <code>FileMonitor</code>.
+ The delay setting controls how often the <code>FileMonitor</code> checks for changes
+ and since there is only a single <code>FileMonitor</code>, only the largest value
+ specified on any <code>VFSFileMonitorReloadingStrategy</code> is used.
+ In the example below both test.properties and settings.xml would be checked for changes
+ once per minute.
