parseOn method

  1. @override
Result<R> parseOn(
  1. Context context
)
override

Parses the given context.

Overridden in concrete subclasses to implement the parser-specific logic. Takes a parse context and returns the resulting context, which is either a Success or Failure context.

Implementation

@override
Result<R> parseOn(Context context) {
  final result = delegate.parseOn(context);
  if (result is Success<R> && !predicate(result.value)) {
    return factory(context, result);
  }
  return result;
}
