Description

An object-oriented representation of a PCRE regular expression is created from class CL_ABAP_REGEX. 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 handler. When the regular expression is matched, the interface method CALLOUT is called for each callout position and can access the passed parameter.
