* <h3>2. Filter Example</h3>
*
* Choosing which directories and files to process can be a key aspect
* This is much simpler than the previous example, and is why it is the preferred
* option for filtering.

* <h3>3. Cancellation</h3>
*
* The DirectoryWalker contains some of the logic required for cancel processing.
* <p>
* Two possible scenarios are envisaged for cancellation:
* <ul>
- * <li><a href="#external">3.1 External / Multi-threaded</a> - cancellation being
+ * <li><a href="#DirectoryWalker_external">3.1 External / Multi-threaded</a> - cancellation being
* decided/initiated by an external process.</li>
- * <li><a href="#internal">3.2 Internal</a> - cancellation being decided/initiated
+ * <li><a href="#DirectoryWalker_internal">3.2 Internal</a> - cancellation being decided/initiated
* from within a DirectoryWalker implementation.</li>
* </ul>
* <p>
* The following sections provide example implementations for these two different
* scenarios.
*
- * <a name="external"></a>
+ * <a id="DirectoryWalker_external"></a>
* <h4>3.1 External / Multi-threaded</h4>
*
* This example provides a public <code>cancel()</code> method that can be
* }
* </pre>
*
- * <a name="internal"></a>
+ * <a id="DirectoryWalker_internal"></a>
* <h4>3.2 Internal</h4>
*
* This shows an example of how internal cancellation processing could be implemented.
