Suggestion made in subsequent push; thanks.

It can be done with a snippet region like this:


     *  // @link region substring="Pattern.matches" target ="java.util.regex.Pattern#matches"
     *  if (Pattern.matches(fpRegex, myString))
     *      Double.valueOf(myString); // Will not throw NumberFormatException
     * // @end
