-Dregex is a Java library that implements a regular expression engine using deterministic finite automata (DFA). It supports some Perl-style features and yet retains linear matching time. It can, additionally, do set operations (union, intersection, and difference).

-For cases when advanced Perl-style features are not needed, and predictable performance is desired, using DFA-based matching is usually a compelling alternative, unfortunately made difficult by the scarcity of proper implementations in most languages. Dregex offers an alternative for the Java ecosystem.
