ComponentClass::class_empty should only be used on finalized classes to determine whether a given class contains any elements; it should not take the cr_ucp or cps_ucp into account, as they have been folden in by the finalize call. Fixes our failure to identify that the pattern /[^\D\d]/8W can never match.
Hyperscan
Hyperscan is a high-performance multiple regex matching library. It follows the regular expression syntax of the commonly-used libpcre library, but is a standalone library with its own C API.
Hyperscan uses hybrid automata techniques to allow simultaneous matching of large numbers (up to tens of thousands) of regular expressions and for the matching of regular expressions across streams of data.
Hyperscan is typically used in a DPI library stack.
Documentation
Information on building the Hyperscan library and using its API is available in the Developer Reference Guide.
