Examples of java.util.regex.Matcher.reset()

java.util.regex.Matcher.reset()
Resets this matcher.
Resetting a matcher discards all of its explicit state information and sets its append position to zero. The matcher's region is set to the default region, which is its entire character sequence. The anchoring and transparency of this matcher's region boundaries are unaffected. @return This matcher

        Matcher matcher = null;
        for (String appPath : unfilteredAppPaths) {
            if (matcher == null) {
                matcher = filter.matcher(appPath);

                matcher.reset(appPath);
