/**
* 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.
