  /**
   * Filters files using the supplied wildcards.
   * <p>
   * This filter selects files, but not directories, based on one or more wildcards
   * and using case-sensitive comparison.
   * <p>
   * The wildcard matcher uses the characters '?' and '*' to represent a
   * single or multiple wildcard characters.
   * This is the same as often found on Dos/Unix command lines.
   * The extension check is case-sensitive.
   * See {@link FilenameUtils#wildcardMatch(String, String)} for more information.
   * <p>
   * For example:
   * <pre>
   * File dir = new File(".");
   * FileFilter fileFilter = new WildcardFilter("*test*.java~*~");
   * File[] files = dir.listFiles(fileFilter);
   * for (int i = 0; i < files.length; i++) {
   *   System.out.println(files[i]);
   * }
   * </pre>

   * @deprecated Use WilcardFileFilter. Deprecated as this class performs directory
   * filtering which it shouldn't do, but that can't be removed due to compatability.
