From source file:org.apache.bval.jsr.util.PathNavigation.java

private static String parseQuotedString(CharSequence path, PathPosition pos) throws Exception {
    int len = path.length();
    int start = pos.getIndex();
    if (start < len) {
        char quote = path.charAt(start);
        pos.next();/*from www . j  av  a2s  .  com*/
        StringWriter w = new StringWriter();
        while (pos.getIndex() < len) {
            int here = pos.getIndex();
            // look for matching quote
            if (path.charAt(here) == quote) {
                pos.next();
                return w.toString();
            }
            int codePoints = StringEscapeUtils.UNESCAPE_JAVA.translate(path, here, w);
            if (codePoints == 0) {
                w.write(Character.toChars(Character.codePointAt(path, here)));
                pos.next();
            } else {
                for (int i = 0; i < codePoints; i++) {
                    pos.plus(Character.charCount(Character.codePointAt(path, pos.getIndex())));
                }
            }
        }
        // if reached, reset due to no ending quote found
        pos.setIndex(start);
