applyRule method

  1. @override
Delta applyRule(
  1. Document document,
  2. int index, {
  3. int? len,
  4. Object? data,
  5. Attribute? attribute,
})
override

Applies heuristic rule to an operation on a document and returns resulting Delta.

Implementation

@override
Delta applyRule(
  Document document,
  int index, {
  int? len,
  Object? data,
  Attribute? attribute,
}) {
  final itr = DeltaIterator(document.toDelta())..skip(index + len!);

  return Delta()
    ..retain(index)
    ..delete(itr.hasNext ? len : len - 1);
}
