This evaluator supports building and traversing NFA's based on Regular Expressions that support the following actions:
a + b
(union)ab
(concatenation)a*
(Kleene star)// NFA representing the RE: ((a + b)c)*
Nfa* a = Nfa::simple("a");
Nfa* b = Nfa::simple("b");
Nfa* c = Nfa::simple("c");
a->unite(b);
a->concatenate(c);
a->star();
// Run strings on the Nfa
a->isValidString("acbc", false); // returns true
a->isValidString("acacacac", false); // returns true
a->isValidString("xyz", false); // returns false
The booleans being passed into isValidString
determine whether the evaluation should occur in parallel or not.
NOTE: Parallel evaluation is currently broken
