| <section name="Description"> |
| <p> |
| This tag creates a <code>FileScanner</code> object so that you can loop over the contents of an Ant |
| <a href="http://ant.apache.org/manual/CoreTypes/fileset.html">fileset</a>. |
| </p> |
| <p> |
| The <code>FileScanner</code> object has the following useful methods: |
| <ul> |
| <li><code>Iterator iterator()</code>: returns an iterator of the files in the nested filesets.</li> |
| <li><code>Iterator directories()</code>: returns an iterator of the directories in the nested filesets.</li> |
| <li><code>boolean hasFiles()</code>: returns true if there are files in the nested filesets..</li> |
| </ul> |
