@override bool evaluate(String input)

Implementation

@override
bool evaluate(String input) {
  if (!hasValidInput(input)) return false;
  final eClosure = epsilonClosure(initialState);
  final states = eClosure
      .map((closureState) => extendedTransition(closureState, input))
      .reduce((a, b) => {...a, ...b});
  return states.any(finalStates.contains);
}
