extract method

@override List extract(dynamic input)

Process input and extract necessary data.

• Note: the output is usually passed to the next extractor in the chain.

Implementation

@override
List extract(input) {
  final inputSource = RegexExtractor.prepareInputSource(input);

  if (inputSource == null) {
    return [];
  } else {
    final hasMatch = _regExpList.where((regExp) => regExp.hasMatch(inputSource)).isNotEmpty;
    return hasMatch ? [inputSource] : [];
  }
}
