Finite state automata to regex archive#
This package supports operations such as complement (the operator) and. This means: The notion of 'regular expressions' used here has exactly the expressiveness of good old regular languages. View the online javadoc API specifications. This package uses deterministic finite-state automata (DFA), unlike most other regexp-packages that are based on nondeterministic automata (NFA).The full source code and documentation is available under the It uses a symbolic representationīased on intervals of Unicode characters. In contrast to many other automaton/regexp packages, this package isįast, compact, and implements real, unrestricted Non-standard ones (intersection, complement, etc.) It turns out that for any regular expression, a deterministic finite automaton (DFA) can be constructed that recognizes any string that the regular. Operations (concatenation, union, Kleene star) and a number of
Finite state automata to regex how to#
This video shows you how to convert a simple regular expression to a finite-state automaton (FSA). This Java package contains a DFA/NFA (finite-state automata) implementation with UnicodeĪlphabet (UTF16) and support for the standard regular expression Finite-state automatons are also called finite-state machi.
