<a href="../../../../../org/apache/commons/io/monitor/FileEntry.html#newChildInstance-java.io.File-"><code>newChildInstance(File)</code></a> to return a new instance of the appropriate type.
You may also want to override the <a href="../../../../../org/apache/commons/io/monitor/FileEntry.html#refresh-java.io.File-"><code>refresh(File)</code></a> method.
