The regular expression contains the special characters (?C...) for callouts. The first three callouts pass numerical data, the other two pass string data. A local class ‘handle_regex’ implements the interface IF_ABAP_MATCHER_CALLOUT and an instance of that class is set as the callout ...
IsMatch(String, String, RegexOptions)Indicates whether the regular expression finds a match in the input string, using the regular expression specified in the pattern parameter and the matching options supplied in the options parameter.
