      • getIntGroups

        public static int[] getIntGroups​(java.util.regex.Matcher matcher)
        Returns an array of integer versions from the available groups of the given matcher. null groups will be counted as zero. That is, if a matcher contains groups "2", "3", and "null", the array {2, 3, 0} will be returned.
        Parameters:
        matcher - The matcher for which an integer array of group values should be returned.
        Returns:
        An array of integers representing the integer values of the matcher groups.
        Throws:
        java.lang.IllegalArgumentException - if one of the matcher's groups is not null and cannot be parsed as an integer.

        public static int[] getIntGroups​(java.util.regex.Matcher matcher,
                                 int beginGroupNumber)
