/**
 * 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>
 * <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>
 * <p>
 * For example:
 * </p>
 * <h2>Using Classic IO</h2>
 * <pre>
 * File dir = new File(".");
 * FileFilter fileFilter = new WildcardFilter("*test*.java~*~");
 * File[] files = dir.listFiles(fileFilter);
 * for (String file : files) {
 *     System.out.println(file);
 * }
 * </pre>
 *
 * <h2>Using NIO</h2>
 * <pre>
 * final Path dir = Paths.get("");
 * final AccumulatorPathVisitor visitor = AccumulatorPathVisitor.withLongCounters(new WildcardFilter("*test*.java~*~"));
 * //
 * // Walk one dir
 * Files.<b>walkFileTree</b>(dir, Collections.emptySet(), 1, visitor);
 * System.out.println(visitor.getPathCounters());
 * System.out.println(visitor.getFileList());
 * //
 * visitor.getPathCounters().reset();
 * //
 * // Walk dir tree
 * Files.<b>walkFileTree</b>(dir, visitor);
 * System.out.println(visitor.getPathCounters());
 * System.out.println(visitor.getDirList());
 * System.out.println(visitor.getFileList());
 * </pre>
 *
 * @since 1.1
 * @deprecated Use WildcardFileFilter. Deprecated as this class performs directory
 * filtering which it shouldn't do, but that can't be removed due to compatibility.
